My pleasure - glad to help out!

Thanks for sharing this. I don't use mine for your application regularly, but I did test it without issue. That said, cables are notorious for not meeting their advertised specs which I believe has alot to do with all the HDMI handshake issues everyone experiences. LTT did a video on this where they purchased far more cables than any of us could afford and then tested them with a cable tester. I was disappointed, but not really surprised at how many cables failed to meet spec, notably when pushed to the upper bandwidth requirements (even this was only short term testing). I've had cables "go bad" after working for a while - sometimes I was able to trace the issue back to rfi/emi and occasionally adding ferrite cores helped. Not sure if your issue is related to cables or interference, but it is worth checking out... High spec cables have let me down before.

I think it’s ultimately a compatibility problem. The Roku does the same job without error, and the UHD Blu Ray player also does the job as long as I bypass the EZcoo (it has 2 HDMI outputs). By the way, I really like your videos so far. You happen to occupy a very specific niche that interests me, being the crossover of older video game consoles and DIY audio/video production. I also like that your videos are generally pretty succinct. It makes them more easily digestible…a nice low price of entry!

Much appreciated - I keep working to improve my reviews and tutorials (hope each one gets a little better). Thanks again for sharing the details on your setup and use case - really helpful for the community!

Sir, I have a multipart follow-up question for you, since you’ve used two of these and you also speak English. Have you successfully utilized the optical out, and have you successfully changed the EDID settings by interfacing with a PC? My receiver ended up dying yesterday so I’m now trying to use this matrix to split the audio off via the optical out to an older receiver. The problem is, it doesn’t seem to be sending an optical signal out (I’ve tested other optical devices on the receiver so I can verify it’s a problem with the EZCOO.) The manual pamphlet is poorly written, but it seems I can turn the optical output on and off using EDID functionality through interfacing with a PC. But the interface is reminiscent of 1995 Windows functionality and the English description is apparently beyond my comprehension. What’s your experience been with this?

Great question! Yes, I have used the optical out with PC, PS4, the Portta Component to HDMI Converter, and Blu-ray HDMI sources. Depending on what source(s) you are using, ensure they are setup to send audio over HDMI after you have connected them to the matrix (the setting on your source can sometimes change after connecting it to the matrix depending on what monitors you have connected to the matrix). Your source reads information about video and audio modes (among other info) using EDID based upon the HDMI monitors you have connected to the matrix. First try using the DIP switch set to Test Mode (1-on, 2-4 off) and see if you get sound. If you still don't have sound, continue on to the steps below. If your receiver doesn't support the mode your source is reading from your monitor(s), the receiver will not produce audio. This is where the matrix allows you to configure specific EDID information to be shared with your source(s). The problem you are having often occurs when your receiver is pre-4K and you are using 4K monitors on the matrix HDMI outputs. In this case, the default EDID information could be unrecognizable by your receiver and no sound will be heard. In addition to the common EDID audio settings that can be configured using the dip switches, the EZCOO matrix allows you to select from among 16 specific Audio/Video modes. These are the available modes: 1-1080P60Hz_2CH(PCM)_HDR 2-1080P60Hz_6CH_HDR 3-1080P60Hz_8CH_HDR 4-1080P_3D_2CH(PCM)_HDR 5-1080P_3D_6CH_HDR 6-1080P_3D_8CH_HDR 7-4K30Hz_3D_2CH(PCM)_HDR 8-4K30Hz_3D_6CH_HDR 9-4K30Hz_3D_8CH_HDR 10-4K60Hz(Y420)_3D_2CH(PCM)_HDR 11-4K60Hz(Y420)_3D_6CH_HDR 12-4K60Hz(Y420)_3D_8CH_HDR 13-4K60Hz(Y444)_3D_2CH(PCM)_HDR 14-4K60Hz(Y444)_3D_6CH_HDR 15-4K60Hz(Y444)_3D_8CH_HDR 16- USER EDID Find a mode that is compatible with your receiver. You can then use the control/update tool available from the EZCOO website easycoolav.com/tmp/madeimg/MX42PRO%20Update%20and%20setting%20kit.rar to set the specific EDID mode for the matrix audio output. It downloads as a rar file that will need to be extracted using a tool such as 7-zip. Connect the matrix to your PC first, and then run the tool. At the bottom of the tool window you need to enter: EZS IN0 EDID# (where # is replaced with the mode you need 1-16) and then click send. This will set the EDID for all inputs to tell your source what kind of digital audio to send. If you are unsure of the modes supported by your receiver, you can repeat this step sending a new mode command. The matrix supports sending a wide range of audio/video modes via EDID 2-channel (stereo), 6 channel (5.1), and 8 channel (7.1). Hope this helps out!

I met him back in 2017. His role as "the captain" has afforded him the opportunity to speak with some fascinating (sorry, bad Spock pun) people and I found he had some very interesting insights as I spoke with him. Glad he had the chance to make it into space...

Hello and thanks! I found this works well straight out of the box and haven’t needed to update firmware.

@@askdrtk ahhh ok awesome ! thank you very much for your feedback !!

Glad to help out! I have have been using two of these for almost two years now and they have proved to be very reliable. I still think they are some of the best value available for an HDMI matrix. That said, as we move into the HDMI 2.1 era, I am starting to see some more "affordable" options becoming available. About six months ago, a 4x2 matrix like the ezcoo but with HDMI 2.1 support (120Hz, 8K, VRR, etc.) were well over $1000 USD. There is now a $200 USD range option available (still 3x the price of the ezcoo). I haven't tested it out yet, but here is a link if you are interested: amzn.to/3Saq1Mo That said, if you are good with HDMI 2.0, I definitely recommend the ezcoo matrix and have no plans to retire mine any time soon.

@@askdrtk that one you linked doesn't actually allow 2 sources to both out 4k120 at the same time. sadly it seems only the $1000 options are truly capable of hdmi 2.1 matrix currently

The "affordable" option hasn't been available for the last few weeks, probably due to not meeting its specs... Yes, $1000 option only at this point, but I suspect that just as with the HDMI 2.0 release, prices will come down soon. The best HDMI 2.1 device I have tested that can switch/split (not matrix, but a choice from 1 or 2 inputs 4k120 mirrored to 2 outputs 4k120) is the OREI BK-22. It has been sold out for a while however OREI informs me we are a few weeks away from new stock availability.

Thanks! This matrix is limited to HDMI 2.0 only (no DisplayPort) and will limit refresh to 60Hz. Combination HDMI and DisplayPort matrix switchers are rare and expensive. If your monitor supports 120Hz over HDMI (an HDMI 2.1 monitor) then there are a few options starting to become available. If this is the case you could use one HDMI cable and one DisplayPort 1.4 to HDMI 2.1 adapter from you video card to this 4x2 HDMI 2.1 matrix: amzn.to/3Saq1Mo to provide both 60Hz and 120Hz HDMI signals to your monitors. Again, this will only work if your monitor supports 120Hz over HDMI. With this configuration, you will be able to switch up to 8K60 or 4K120 (including VRR) - really nice for future considerations... The HDMI 2.1 matrix I linked is currently selling for around $220usd, which is expensive, but considering the only option to do this six months ago with well over $1K. I suspect that HDMI 2.1 gear will continue to come down in price this year. Hope this helps out!

Oh and do you maybe also know, if a hdmi to dp cable would work on the switch? Or could it cause some issues?

Glad to help out! There is no way I am aware of the setup outputs and inputs on this unit (it is not bi-directional mostly due to it processing the signal for scaling). I have used and hdmi to dp on an output (and dp to hdmi for input) and found both to work, although not all monitors may work well with hdmi to dp.

Hi - great question. Since making this video I have set one up with a 25m fibre optic cable sending 4k60 and it works flawlessly. I have found the matrix to have a strong signal amplifier - tested an 8m standard HDMI 2.0 cable and two 8m cables with a repeater in the middle, also without issues, although I prefer not to use any standard HDMI 2.0 cable over 5m as it can put strain on the output. Hope this helps out!

Glad to help out! There aren't any presents to auto configure the inputs/outputs, you have choose which of the 4 inputs you want to display on either (or even both) monitors. All of the configurations you are looking for will work, but this matrix only has 4 inputs and it sounds like you need 6 (2 for each PC, 1 for the XBOX, and 1 for the PS5) so you will end up swapping cables. I 6x2 (6 inputs, 2 outputs) matrix would be a better choice. I would suggest the OREI HD-602. It is excellent quality and will cover every combination you are looking for with out needing to swap cables. It is HDMI 2.0, so you are limited to 60HX (no 120Hz / VRR for the consoles). Here is a link to the OREI matrix: www.orei.com/products/hd602-6-in-2-hdmi-matrix Hope this helps out!

@@askdrtk Fantastic, thanks again :) Do you happen to know if there's an HDMI matrix like this that also supports KVM functionality?

Yes, this one from TESmart is my favorite (until an HDMI 2.1 with vrr become available). It is a bit more expensive, but it will do exactly what you are looking for. www.tesmart.com/collections/dual-monitor/products/tesmart-hdmi-dual-monitor-kvm-switch4x2

I tested mine with my Yamaha and Denon receivers using Xbox and BluRay and it worked in 1080p and 4K but doesn’t support ARC or CEC. I had the dip switch set to pass EDID. If you let me know which AVR and config you are trying I will look into it further.

Hi and great question! I have tested 1440p working on both passthrough and downscaled to 1080p. You should be good to go with your setup.

This is not an external video card and so it will not not extend your display across two monitors. This matrix allows you to input up to four HDMI sources (could be PC’s, consoles, streaming boxes, etc.) and output them in any arrangement to two monitors or TV’s. You can have any one of the four inputs on either of the two outputs, or you can have the same input on both outputs. It will also downscale 4K to 1080p, but it doesn’t extend desktops. HDMI doesn’t typically allow you to use two monitors to extend desktop area with one cable other than if you are using a very expensive signal processor to make your PC see two monitors as one. Sorry this isn’t what you are looking for but I hope this helps out.

Yes, you can set the output of either HDMI port to "Pass" or "1080p" using the dip switches on the front. In "Pass" mode, the matrix will not process the input signal and send it directly to the output. For example, if you are gaming in 4k on your monitor and want to capture (stream or record) at 1080p, set output 1 to "pass" (connect to your monitor) and output 2 to "1080p" (connect to your capture card. This way you can use a capture card that only supports 1080p and still game at 4k with no lag. It also means your capture card doesn't need to have a passthrough. Hope this helps out and thanks for the question!

@@askdrtk thanks! My capture card is an elgato HD 60 Pro and has pass-through enabled by default. Glad I don't have to constantly change my HDMI cables every time I wanna switch my consoles now!

In my case, the flicker on camera is due to the shutter speed on my camera and not present when watching the screen directly. I do have a couple of suggestions that may help out. The first thing I would try is placing the EDID switch in “Copy” mode, set both DIP switches in the ip position, and connect the ultra idle to output 1. This generally improves compatibility with a variety of refresh rates and resolutions. If this doesn’t solve the issue, I would download the “Update and Setting” kit and perform the update. You will then have access to additional EDID options including User Defined. I don’t believe you will need to change settings from the software, but the option is there. If these solutions do not help, let me know the details of your monitor/graphics card and mode you are trying to use and I will look into the settings further. Hope this helps out!

I have inputs 1 and 2 connected from two of my PC outputs and route input 1 to output 1 and input 2 to output 2 on the matrix. This would be the standard configuration, which then leaves inputs 3 and 4 available to use other devices with either of your monitors. Hope this helps out!

If I am using audio over HDMI, I let the matrix take care of that. For analogue signals, I use a combination of my patchbay (48 port Samson S-Patch), Soundcraft EFX mixer, and routing through my Focusrite audio interface.

Hi there - Yes you can. When you select an input to be routed to either of the two outputs, the audio from the selected video input is sent as well. (both audio and video are routed together) This allows you to select one of the four input's video/audio to be sent to either or both of the outputs. Thanks for the question and hope this helps out!

@@askdrtk Yes but I have this setup: TV 1 (pc signal). TV 2 (laptop signal). I can change the audio? alternate Audio A and Audio B?

OK - Audio and video are switched together, so you cannot have pc video with laptop audio or laptop video with pc audio on the same TV. TO accomplish this, you would need to extract the audio from each HDMI source, mute the original audio, and then combine the alternate extracted audio back into an HDMI source. I am not aware of a stand alone device that does this (would be great to find one), but it may be possible using a series of switches and extractors. I will look take a further look into this and let you know if I come up with anything. For anyone reading this looking for clarification, this matrix (an all others I am aware of) in this example allows you to route the pc signal (both audio and video) to either TV 1, TV 2, or both and the laptop signal (both audio and video) to either TV 1, TV 2, or both. Since there are 4 inputs, you could add 2 game consoles or other sources as well.

Extending is not possible with a single HDMI source. If your computer has two HDMI outputs, you could connect both to the matrix, setup extended desktop on your computer, and pass each though to an output on the matrix. This way you get extended desktop and can still switch your monitors between two additional sources. This is good if you use extended desktop on your computer but also want to share your monitors with other devices (consoles, etc.) Hope this helps out!

@@askdrtk but then it'll only be used for 2 computers. If both computers give out 2 HDMI each.. so its basically become a 2x2 matrix nvm switch.. right?.. Any suggestions on how I can achieve 4 computers on 2 monitors kvm switch solution but NOT duplicated displays.. want to have 2 separate monitors to work on

If you have 4 computers that you want to share dual monitors for extended desktop, you will need a 4 port dual monitor KVM switch. The two that I recommend are the TESmart HKS0802A1U here: www.tesmart.com/collections/dual-monitor/products/tesmart-hdmi-dual-monitor-kvm-switch4x2 or the CKL-942HUW-3 here: CKLcklkvm.com/products/4-port-usb-3-0-hdmi-kvm-switch-dual-monitor-4k-60hz .Both of these units will switch two monitors in extended mode across 4 computers and will also handle your usb switching for keyboard / mouse. Note that the TESmart switches usb 2.0 and the CKL switches usb 3.0. These are both more expensive vs an HDMI matrix such as the EZCOO, but they both provide a complete KWM solution. Hope this helps out.

Great question! I have tested 1080p at 120fps into two monitors at the same time and it works flawlessly. I haven't been able to test 144, however the bandwidth required fits within the specs and I have heard of others running 144. The main limitation with this matrix is 60 fps in 4K (bandwidth and downscaling limitation) - to get above that is $$$ Hope this helps out and thanks again for checking out my review!

Thanks for the question. I can confirm this matrix will display 4k on both outputs as long as the source is 4k and both displays support 4k. If one source is 1080p and the other 4k, each source is routed independently to the outputs and does not affect the resolution displayed for the other source It can be set to downscale 4k to 1080p on either or both outputs however it is not an upscaler, so 1080p sources will always be passed through at 1080p. This matrix will do what you are looking for with the Switch and PS5, however it is HDMI 2.0, not 2.1 so VRR will not be available and 4k will be limited to 60Hz. There are a few new HDMI 2.1 4x2 matrix devices starting to become available that do support 4k VRR, however as with all new standard adoptions they are very expensive. I believe the avpro is about $1250 usd... Hope this helps out!

@@askdrtk thanks i will order one.

Glad to help out!

@@askdrtk HDMI Matrix 4x2 4K 60Hz 4:4:4 HDR 10 Atmos Easy EDID 4K/2K/Scaler Switch - D-o-l-b-y Vision Atmos in Sync,17 EDID Mode,Set HDCP by PC, HDMI Down Scaler 4K 1080P Sync, RS232 IR Ext. Remote MX42HS. One last question what’s the difference between my link and yours. They look similar but cost is 50 bucks difference

The more expensive version includes audio extraction with optical output as well as more flexible onboard EDID configuration that does not require connection to a computer. Unless you require optical audio, I haven't found a need to upgrade.

To show all four inputs on one screen you need a matrix or switch that supports multi-view or "multiplexing." Unfortunately the EZCOO does not have this feature. A very good option is the OREI UHD-401MV (up to 4K60). I haven't found an HDMI 2.1 option to support this as of yet.

Oh thank you very much I was pulling my hair out with this and though you could configure through network settings but you’re right it only does the 4 inputs with 4 outputs and no 4x1 on one screen. I brought a switch instead thank you so much for the explanation.

There is a known bug with surround sound compatibility from the Shield. Try disabling surround sound on the Shield and see if the noise goes away. Hope this helps out.

@@askdrtk Thanks for your help it worked. I changed the settings in sound and turned on night listening mode which turns off surround sound.

Latency is only introduced when using the matrix to downscale 4k to 1080p, on pass through there is none perceptible. I use this with PC, PS4, and other consoles for gaming on the pass through mode with no additional lag. Hope this helps out!

@@askdrtk awesome thank you for your reply. One other question if you don't mind. The power supply, does it allow 110V - 240V ? Can't find anywhere? Also Thoughts on the Orei BK-22? Thanks mate

No worries, glad to help! The power supply I received is auto switching between 110-240V. The Orei BK-22 is a great device. I found it to be top quality and perform very well. It isn't a matrix, so you cannot send different inputs to each outputs (both outputs are the same souce), but is handles variable refresh perfectly in my experience. I reviewed it here: kzfaq.info/get/bejne/d9ODd7aXr8zYdaM.html

@@askdrtk thanks heaps again mate. Think I may have found another way for my needs. I'm after a 1 in 2 out splitter that can handle 1440p at 120hz. Do you know of a good one? Please

At this point I would say the BK-22 is your best bet. I am not aware of a 1x2 splitter that will handle 120hz (I've been watching), it seems the first batch of splitters supporting 120Hz are coming as combo switch splitters. In your case you would only use one of the inputs and the both outputs will display the signal (a splitter). An advantage of going with the BK-22 is if you end up with another device you want to use with both displays, you are good to go + you are future proofed for awhile with 4k120. HDFury also makes a great 120Hz matrix, but it is $$$. As of now, the BK-22 is tough to beat in term of performance, quality, and overall value.

No , this one is HDMI 2.0. The 120 Hz (HDMI 2.1) matrix options have been very limited and expensive. So far, 4x2 matrix options for HDMI 2.1 are limited (AVPro Edge is $1200 USD), but just as with the early days of HDMI 2.0, I expect affordable options to start showing up soon. If you don't need a matrix function and can get away with switching between two inputs and mirroring on two screens (or screen and soundbar), the OREI BK-22 is the best affordable option I have tested so far for 120Hz, VRR, etc. I reviewed it here: kzfaq.info/get/bejne/d9ODd7aXr8zYdaM.html Hope this helps out.

Great question! It accepts either IR or control via RS232. To use a hotkey (and/or Stream Deck) for control you would need either an IR transmitter (blaster) connected to your PC or a usb to serial cable for a hard wired connection, but either way it can be done. Hope this helps out!

@@askdrtk Thank you for answer! But I think I made mistake... I have ezcoo EZ-SW41HA-KVM HDMI V2.0 KVM . But I can`t use hotkeys on my keyboard. I don`t understand what happens.

I don't have that specific switch, but I have found not all keyboards to be compatible with KVM hotkey switching. Does switching with your mouse work? If not, while it may seem obvious, make sure the mouse is plugged into usb 1 and the keyboard into usb 2 (I have gotten them reversed before). If you can, trying another keyboard may also be helpful in testing for compatibility,

I don`t use IR or control via RS232 in this case.. Am I right?

Yes, although you can use IR with your KVM, you shouldn't need to as the switch should pickup your key combinations or mouse actions.
