You can turn it on without a remote and change input. The button is behind the light bar on the bottom center ofthe TV.

Did this today on my TCL 40". Used your video as a how to guide. Worked great. Thank you.

Thank you. I was looking for a way for the tv to go straight to the computer and you provided the way!

A big benefit of using a big 4k TV as a monitor is, at 100% resolution you have the equivalent of four 1080P monitors. If you scale it up to 150%, you lose 25% of your 4K screen real estate compared to 100% scaling. To keep all of your screen real estate, you have to go bigger. 55" or 60" is the sweet spot IMHO. I understand the desire to go with a 43" like you did, because a 55" just SEEMS too big, but its not. If you imagine four 1080P monitors arranged in a four-monitor array, it should be about 55" or 60". Also, with a 55" 4K TV, the 100% resolution doesn't make the text too small like it does on a 43" television so you don't have to scale it. So if you're going to use a 4K television as a monitor, I recommend getting at least 50", but 55" or 60" is better. I have a 55" Samsung as my main monitor on my Linux desktop machine, and I use a 50" TCL as the main monitor for my Macbook Pro laptop, because I just so happened to already have it. I am going to have to spend two months working in Houston this spring, and am not taking my desktop or big televisions with me, so I am buying a 55" or 60" TCL to use a monitor with my two M2 Macbook Pros (one at a time), while I am there. When the two months are over I'll probably give the TCL away to someone before coming home. My sister lives in Houston so I'll probably give the TCL to one of her college aged kids. By the way I am a software architect / computer hacker, I use linux 75% of the time, MacOS 20% of the time and Windows about 5% of the time. I don't use my computers to play games AT ALL and am plenty happy with 60Hz native refresh rate, though I wouldn't kick 120Hz out of bed; so take my advice for what it cost ya'.

thank you sir. very good video

thank you brother very help full video thank you thank you thank you........................

Very informative. Wanted to buy 50 inch for home office but I think 43 will work right enough. Thanks

Hi there. Does it support 4:4:4? On 100% resolution scale at 4k, do texts looks crisp? Test with rtings image test.

I've been using 4k TVs for many years now. 4k monitors are ridiculously priced and modern TVs have as high response times as mid range monitors. Just today I bought the 55" TCL to replace my aging 50" Vizio P series as it's local dimming zones were starting to die. That TV cost me over $700 and this was far cheaper and supports 4:4:4 chroma. The only drawback to the TCL is no 120hz period where the Vizio supported 120hz at 1440 and below. Kinda sucks for gaming but 60hz is more than playable as long as there's no input lag. Just don't expect to be doing super competitive FPSs where high framerates are needed.

I have had this for a few years and still use it everyday. I like it for the most part but I have not been able to have it turn on and shut off with the computer signal (or absence of) even when set to computer in the menu. It drives me nuts to have to turn it on and off manually every time I use it with a computer.

Thanks for the great video. I like the 4 browser layout setup. Looks great! Wondering if my Chromebook support this TV as a 4K monitor. Would you happen to know? Thanks again.

Target just had a sale for the Android version of this TCL TV for $170. I ordered it and can't wait to replace my 34" monitor with this monster!

Can also turn on from TV without remote,there is a button under the TV in the center behind were it lights up but annoying to use

i have a 65s425 4k@60 1080p@60 but 1440p@30, it was working great since nov 2018, until HDMI start to make funny things, 4k via HDMI is DEAD, my GPU is DEAD too, TV still work 4k from streaming wifi, but not from HDMI. i dont know if TV killed the GPU or GPU killed the HDMI ports. besides HDMI still works "fine" at 1080p or inferior. im thinking replacing main motherboard is like $75 US.

thank you jan 6 2021

Have you had any issues with burn in? Can you make a video about what it’s been like since you started using it

I have a 32 inch my power switch is in back the bottom left of the tv, you just have to look for it

Is this tv good for doing work also? Typing, writing, etc.?

My 2070 super isn't seeing it as a 4k TV for some reason I had to manually set it to the 4k scaling, but it's annoying me and I wish I knew why it would auto see it.

So when you switch to the the hdmi input that the tower is connected to the keyboard works instead of remote?

is working with ms word or excel okay? Does it display clear texts? Monitors are made to work with small things on screen but TVs are not generally... But that may be an old story, so I am asking for your experience. Thanks for your posting

I just got a TCL 43S431 and connected it to my laptop. Windows claimed it had a max resolution of 1920 x 1080. I connected & disconnected it a few times, and eventually Windows (10) popped up a notice that the external display had a max res of 3840x2550 or whatever, but that currently-running applications would need to be restarted. I shut down all apps and started them again, with no effect. Then I turned the computer off, and it said it was updating Windows, for a long time. I turned it off when it was done, then turned it on. It went back to installing updates. Eventually the login appeared, but the keyboard wouldn't work anymore. I turned it off and on again. It installed more updates again. Then the keyboard worked, I logged in, and now Windows could use the TCL at its full resolution.

I'm having trouble getting my windows machine to recognize the TCL is 60hz capable, and it defaults to 30hz. Any suggestions? My computer is a pretty high-spec'd Dell 7540, using a WD19 docking station... I'd researched this months ago, and supposedly the DisplayPort to HDMI cable I specifically purchased for this was to provide the most bandwidth. Going to try a simple HDMI connection next. Thanks! Edit: I should have stated my goal is to display 4k60hz on this 55" TCL such that I can "tile" and see four HD screens simultaneously.

Nice How sharp is the text ?Is it comfort for many hours of work?

Do u need to connect it to the computer for it to show the Google and if so then what if the computer loses charge would the tv automatically disconnect

Do yoi game with it? If so, hows the input lag?

I have a few questions no one seems to be covering. Is there an advantage to having multiple monitors rather than one big one for Windows 10? Is it easy to divide the screen into sections and have different apps in different sections of the screen maximized? (Sometimes you also want to know how something will look on a standard screen.) What about screen sharing? Can you share only one portion of the screen or do you have to share the whole screen? The advantage of multiple monitors is that you can work on one screen and then move items into the shared screen only when needed. But if you are showing the whole screen you can't hide your work area. What about burn-in because of a static background picture? Thanks!

Can u do this with the android os instead of roku?

I have a TCL 6 series TV and I hooked it up to my PC by using a HDMI cable but it keeps saying no signal(is it on?)

My next investment

Is a 50-55" overkill?

fun fact: This tv is actually 60hz

I am thinking of doing this with my Aorus FV43U, but it feels too big for my setup, how far is the distance of your display to you when you are gaming

4K resolution at 120 hz?

Is the tv still good after using it as a computer monitor?

Has anyone tried tcl 65c815k 65-inch qled?? Will it handle 4k 60 Hz off a 3070? Cheers Dono much about tcl

Is this running at 60hz?

Dont be fololed by this false adverting. 120hz in a tv is actually 60 hz in pc terms. So if you think you will get 120hz, you are sadly mistaken.

whats ur hertz?

Is there a way to force the tv to display 1440p instead of 4k?

my computer is overscan but I can'tt figure out how to fix

Do you need a pc to do this or no?

how to fix tha lag on TV???

I do have a problem - it refuses to recognize my TV as having a framerate of 60fps. Instead, it locks it to 30fps. How can I raise the framerate?

Please help me for the love of god My R655 4k 144hz TCL tv using HDMI 2.1 ports my pc detects the tv as 1080p resolution's native (recommended)
