4:48 YOU HAD ONE JOB MR VIDEO EDITOR!!

For those that don't quite understand the relationship that Linus mentioned between the case fans and the back light, PWN is Pulse Width Modulation. On cooler fans the fan controler turns on and off the full voltage very very fast, resulting in the fan spinning at a constant speed that is dependent on the length of time between voltage "on" cycles. So with the backlights it's the same thing but instead the fan spinning, it makes the light appear to be a less bright as the time between "on" cycles increases. The DC fan control is when the fan control simply reduces the voltage being put out to the fan which makes it spin slower the more the voltage is reduced. With the backlight it makes it dimmer the more voltage is reduced. The DC method is much better for people with Epilepsy or sensitivity to flashing lights or that get migraines easily as the on and off cycles of a PWM backlight may not appear visible to most people, even most that have any of the above conditions, but the eyeball and brain can still partly sense it causing the brain to freak out or get confused, witch can trigger a splitting migraine at the least.

speaking of terrible jokes, our sponsor, audible.com lol

One day, all Linuses in all TechQuickie videos will all be the same color. Orange Linus is funny, green Linus is okay, but I prefer Linus Linus, with authentic Linus reproduction.

Thank you for bringing up the PWM backlighting. I had to return a new laptop due to this as I didn't know why it was giving me horrible headaches whereas my old one didn't. I found a new laptop without PWM and I'm having no problems with it. Another technology for projectors is "single chip" DLP. They display multiple monochrome images every second, and depends on your brain to assemble the color image. I see the rainbows horribly (even on the newest ones) and if I look at one for more than 10 minutes, I have a full-on migraine that puts me down the rest of the day. 3-Chip DLP projectors in theatres obviously don't have this problem, just the single-chip spinning color crap does. I get disillusioned when I see DLP used in public venues such as presentations, etc. I look down at the floor the whole time. It is amazing how many people I hear complaining of eye strain and headaches. LCD technology should be mandatory in a public venue like this; but like some comments I see here; people are either not aware, ignorant, or are not affected by these flashing images; but should have respect to those who have debilitating side-effects from these.

I'm from the year 2030. I'll stick to my MicroLED 8K HDR 240hz 1ms display with no backlight, no screen burn-in and no issues with lifespan/longevity like OLED.

Educational, entertaining and fast. Great content!

Please make a 2021/2022 version of this video? It is an interessting topic!

This is a surprisingly informative video. Nicely done!

Actually needed to pause my viewing so to commend this masterclass of a 'what to know' briefing for the ever increasing number of informed consuming customers. Impeccable.

Techquickie is the best tech learning channel EVERRRRRR!!!

Now I understand the reasoning behind the yellow phosphorous breaking down on my cheap 2 year old vizio now leaving me with a blue/purplish looking screen. I watched videos that explained it was the led's causing the issue, but didn't know about the led design. Thanks Linus

"LCD Display" Liquid Crystal Display display, common Linus!

I'm really thankful for your explanation ...

honestly, I wish you would have covered more display types as this was super interesting. kind of felt like it ended abruptly, but hey I guess it is techquickie.

Linus, you're looking a little green in this vid mate.

Thank you for finally mentioning OLEDS longevity concerns. I've been waiting for someone to finally say something. Of course OLED should improve over time. But back in the Galaxy S3 days well....you can find dozens of forum posts about it. Of course I lost the link when I lost my old bookmarks. :c

I think you forgot to mention Plasma... Although I guess the days of the plasma screens are over.

really answered my question. thank you man

if you want to know what kind of backlight your monitor uses, load up a white screen and wave your finger quickly in front of it, if the blur is smooth, your display is flicker free, if you see multiple copies of your finger in the blur, your screen flickers

Very nice information n useful video.

Back when I bought my first LCD monitor, I did way more research than the average person would. I eventually became fairly disheartened and disappointed, as LCDs definitely do not out-perform CRT monitors in terms of image quality. LCDs may have recently became more powerful in terms of specs, but still arent as versatile in terms of scaling and image quality like the CRTs were. I was also very annoyed to learn that almost every LCD LED-backlit screen contained blue LEDs instead of white or RGB. This makes a considerable difference in quality and also affects eye-health. Too much blue-light = bad, especially if you're about to go to bed. Blue-light filter programs/settings help, but doesnt solve the other problems, and can easily be forgotten about. The part that disappointed me most is how painfully slow the market has been at adopting new technologies that I care about. Higher resolution is not my main priority whatsoever. Color gamut, black-levels, contrast(one of the only things that has improved), viewing-angles and high-hz are what I care about more, and those features have been extremely sparse in the lower-mid end LCD market(and possibly even in the higher-end), and you're almost never going to be able to decently achieve all of them. If more consumers knew the information that Linus shared here in this video, the market would have to adapt to the people requesting/demanding and buying products with those features. I'm sure ill be waiting another 5-10 years since i bought my first LCD before I feel the need to buy my next one. I cant even expect there to be much difference in that amount of time, but I certainly hope there is! I, for one, am tired of LCDs(and especially bluelight LEDs)!

Could you do a Techquickie on IPS and whatever non-IPS would be? I obviously need to be enlightened.

Techquickie as fast as possible please!

I love you and your insane jokes, give my 65” q80r

My monitor has no backlight. It's called a CRT.

6:18 I like how you LED us to believe you were calling Audible a joke

Nice video on 2016. Linus and Techquickie were Far better than 2018.

Love your vids

could you make a video about different sd card classes?

Can u make a video for lan switching(layer 2 vs layer3)?

Explained perfectly

we take everything for granted...

Please do a dynamic vs basic disk as fast as possible!

I was wondering what are the differences between blade servers and rack mount servers I was also wondering if you can make a video for this topic

I remember those gameboy clip-on lights that had a square hole in the middle so you could see the screen.

"And speaking of terrible jokes, audible. com is NOT a terrible joke.." 😂 😂 😂 😂 😂 😂

Good video

God bless you. This review is Gospel.

Small comment on PWM vs DC: PWM dimmers can reach frequencies of up to a few megahertz, now way you can see that. Of course they can be ridiculous slow too. DC dimming comes with another problem: LEDs tend to slightly change their color depending on the current running through them, thus ever so slightly diminishing color reproduction. I'm not sure how noticable this effect is on LCD screens and how well it can be compensated for.

My phone has an OLED display and it is darn gorgeous... but I did notice my keyboard starting to burn into the screen after only a few months. I changed to a third party keyboard that is more subtle to try and patch the issue; This is making my monitor search even tougher.

Once you mentioned that edge-lit displays are found on cheaper screens, I looked at my laptop and noticed that the edge is quite a bit brighter than the middle. The diffuser isn't very good at it's job. Damn Emachines e-627 from 2005! (With Windows 10 and a 1.6GHz S1 CPU)

Thanks. I'm looking at new Dell Monitor. Professional series use LED backlight, Ultrasharp use the newer models LED edgelight, so I was wondering which was better. I think you've answered this.

Just a question, is the backlighting doing the color? Or is it just a white lighting and then the other part of the screen (frontlighting?) is doing all the color work?

Hi Linus, Is there a difference between an "as advertised", LED display and LED backlit LCD? are they the same? If they are not, which one is better.... thank you,, ive been an avid follower of your channels.

Can I swap out the CCFLs in my old LCD TV for LEDs?

linus, you LIGHT up my world ok I'll leave now :(

@2:37 what movie is that image from?

Do one on different types of enter / shift buttons

1:35 Dat cable management do, i want to have it the same way!

Can somebody help me? I need somebody to look up a picture of an Ohmeda 3760 pulse oximeter and tell me about that backlit? I seriously need to know about the backlight that is in this old pulse oximeter! It is a bright green lit display!!! but that's all I know and I need to learn more about this type of backlight! Thank you!

Or why your 2010 Bravia can still kick some 4K QLED butt. Refreshing to see old style Linus, when he still had time to shave. Today he looks like he's still in lockdown and stayin in house day after day.

There is a third type. It sectors off the monitor in 4x4 to 8x8 inch sectors. The edge of these sectors are LED lit.

which backlight technology is used in u series tvs ?

Hi Linus can you make a fast as possible about application such as the many different standalone and other type of software. :)

It’s not as fast as possible when the first half of the clip is a history lesson.

"Speaking of terrible jokes - Audible is not a terrible joke" - Best segway, Linus Sebastian 2016. Let me give you an alternative: "Speaking of dinosaurs with only one arm, that waves furiously at every human it passes - Tunnel Bear is not a dinosaur with only one arm, that waves furiously at every human it passes, it is a service that let's you tunnel from your region to any other...." :'D Man, that segway :D - I liked the video though :D

Looking at all those dots fucked my eyes up.

So what's the best type of Moniter? Is it oled dc or lcd or whatever which one is the best

I was searching for a moniter & came across the spec 'WLED'. So it is a direct, full array or only edge lit ? Because nothing else was mentioned in specs.

Yeah Yeah I saw the LIT, editors be blazing XD

Is it possible? A Tech quickie that communicates more information than what is possible to undestand as an 80 year old?

The System shown at 1:35 is screaming 2007. With a Zalman CNPS 9700 LED, a possible Q6600 and a 8800 GTX

Backlight types and no one mention of Quantum Dots? Cmon LInus.

There are three basic types of displays: Emissive - OLED, Plasma, CRT, VFDs Transmissive - LCDs mainly Reflective - e-readers, calculators, watches

Damn Linus can sell any sponsor while speaking about any subject :p What is his secret?

Which one better 4k dimming or local dimming ?

do you know where I can get the color profile of the AW2720HF Alienware monitor ? because I couldn't fined it anywhere

Where can I find the addressable CCFL header on my motherboard?

I have an HPPavilion Ze2000 from ages ago that i have for android x86, and one thing you can do, is turn off the backlight with a button. What would happen is when you needed to close the laptop the screen would hit the backlight button. This was what we had to do in the age of XP laptops. I now see that a modern laptop will automatically turn the backlight off when it's been closed enough. How does that work? I'm sure it's obvious, but i dont know.... Another question I have like that is pretty dumb(i feel). How does a phone, for example, recognize the rotation? Just wanna learn, don't hate me!! :P Thanks!

"No backlighting" Chooses Gameboy Colour as bait Well chosen, Linus. Well chosen.

Linus, what button are you pressing on your hip all the time?

Linus - BEST. segway. EVAR!

me: cramming for exam linuz from 5+ years ago: I gotchu

Ur awesome!

dear Linus, Computers used to confuse me, but not anymore. Because now, I am one.

They say the same thing about Plasma that they saying now about OLED. Still using the same Plasma Panosonic 720p TV for almost 9 years and it still not burning out.

Can anybody tell me what does the gesture at 2:22 means

What are fpga processers

Hackintosh As Fast As Possible, Please!! Gotta know what all the cool cats are talking about.

my tv has backlighting and sharpness and contrast options setting all my past tv didn't have that option

CCFL is also notorious for deminishing brightness over time. I'm not a fan of led lighting. it doesn't seem to show accurate and full spectrum color. also with rgb (i believe) backlight it just seems as if you are looking at three colors blended together. don't really know how to explain this. with ccfl you will see the colors more as a natural smooth spectrum. I really hope one day there will be screens with individual pixels that consists of just one light emitting pixel that can emit all colors, not three or so next to each other. you will always see it, subconsciously. but most people won't notice until they see it with their own eyes.

This photo on led panel? where is it from? is it just art or there was a film like this?

I have a super cheap CCFL monitor hooked to my laptop. The problem being, the two monitors aren't the same color XD Well, maybe LCD panel type as fast as possible in the future?

there's something i want you to explain programming languages like how they make them ! the compilers and if you didn't understand how did they make android studio (for programming apps )

PWM per se is not the issue. The issue is the frequency of the PWM signal (different from the frequency of the screen). If the LED are driven by an high enough frequency they are not "turning on and off" they start behaving like a low pass filter and oscillate around a target brightness. The higher the frequency the lower the oscillations.

linus can you do a silent fan as fast as possible

i want to buy a monitor for ( movies games and photoshop editing ) which one is batter 4k or 3d .( asus PB287Q 4k or asus mg278q 3d)

do a video about blacklights

So, the way I take it, the most vibrant and less eye straining tv would be a RDG LED tv that has DC backlighting?

How about just small black and white OLED screens? Alot of devices, you have the option. Is it worth paying extra few bucks for the OLED one??

My old laptop had only one ccfl at the bottom, I upgraded it with an led screen.

Perhaps you guys could help me. Or someone else here. My eyes are soaring more and more the newer the technology gets. It feels as if I slowly lose my vision and the eyes are burning red in the mirror when trying new screens. Ive really held strong to my monitor for 7 years now which works terrific! The problem is that I cant seem to understand what Im looking for because I dont understand the technical stuff. The retailer label the hardware as: PNL,15.6HD BV WLED SVA 45%220neDP FL,SDC. Is there someone that knows where I can get the same technology or even suggest a monitor?

Did we already cover Sub-Pixels?

Soooo, since keyboards are also rgb backlit, why dont we have a small display on every mechanical key? Full customizable.

looking very green today linus. you feeling ok?

i still dont get the rgb backlight, because if you can control the color of the individual pixels on the screen, why cant it turn of the local leds when the picture is black? i dont get it why they all must be lit all the time ( i assume theres a reason)

loved that last joke. More puns please.

VR is going to be good for the development/cheapening of OLED though

Do u have any idea why my android phone screen goes on and off while i'm using it?. Sometimes i can use my phone for two hours straight without the screen blinking. Sometimes blinking is continuous and i have to wait for the screen to turn on again. So annoying
