[@thedanielchaniel]

"Infinite contrast" makes sense to me. The reason why some number divided by 0 is undefined is because as you approach 0 from the left (negative) side, the limit of some number / x is negative infinity; but, as you approach 0 from the right (positive) side, it's positive infinity. Because the limits aren't equal, it's undefined. But in the world of contrast ratios, aren't you really only approaching 0 from the positive side? You can't really have a negative brightness anyway. Hence, infinite contrast?

[@498fun]

Daniel Rockcastle Exactly what I was thinking dude. Believe this is true until we have panels that emit negative light. But that's just being black by default, so this logic probably always holds

[@marcospacheco6835]

Hmm?that makes absolute no fucking sense like your math is right and shit but your premise is wrong in order for your statement to be correct you would have to continuously and constantly approach 0 which in my very short research of infinite contrast monitors do not truly exist

[@Seegs108]

Linus, your description is incorrect. The 3000:1 or 1000:1 numbers you're quoting are called on/off or full field contrast numbers. The scene in which you discuss how the bright city lights compare to the dark background would be quantified by an ANSI contrast or intrascene contrast ratio, not on/off contrast. This is because, most of the time, you'll never actually reach the level of on/off contrast the screen is capable of when you have mixed content on screen. On/off contrast numbers are used by manufacturers because, more often than not, they're much larger than ANSI and intrascene contrast numbers. Bigger is better for marketing and is the same reason they quote screen sizes in diagonal measurements instead of width and response time in grey to grey instead of black to black. The numbers you quote in your video (3000:1 and 1000:1) are full field contrast numbers which are measured when the entire screen is at it's peak white output (white level) versus it's lowest output (black level). For dynamic contrast people should also know that in these dynamic contrast modes there is also something called dynamic gamma which occurs to compensate for brightness compression. If we simply lower the brightness of the light source the image will look dull and flat so manufacturers use some gamma adjustment to make the lighter highlights in the image brighter to compensate for the brightness loss.

[@jasonbrittain7110]

yours ago when LED was 1st coming out, I was actually told That each company had thier own set standard for what one unit of light Would-be. so the same panel test of the exact same way at 2 different companies would come-up with 2 different Contrast ratios.

[@ABaumstumpf]

you need roughly a contrast of 10 000 : 1 to really reproduce what a human can see, and over 1 000 000 : 1 to encompass scenarios like being in bright sunlight and then going into a pitch black room. And contrast alone doesn't tell the whole story cause it only says how much brighter the brightest colour is in comparison to the darkest black. But you also need to know how dark the black can become. Otherwise you get a screen that in black scenes is still looking grey but can burn out your eyes with its brightness.

[@lemmiix]

so what monitor do you recommend depending on the contrast ratio?

[@mastergx1]

I get the infinite contrast ratio on the OLEDs. If they can turn the pixel off completely, any number they give for the maximum brightness will be infinitely larger than zero.

[@JimClonk]

3:44 Isn't that sugar? It does have the cube shape salt usually has, but only partially.

[@allanjmcpherson]

Since light output is always nonnegative, there actually isn't a problem treating a ratio relative to zero light as infinite, though it still isn't particularly helpful because it's the same regardless of the maximum brightness of the OLEDs.

[@DETERMINOLOGY]

@ 1:40 this video is still valid. OLEDS look like the one on the left compare to LED/QLEDs that look on the right. Sure the one on the right is brighter by all means but the blooming / lack of contract kills it thus the picture on the left may be dimmer but the detail is perfect you dont lose any detail in the bright/dark areas and everything is balanced. Thus now a QLED isnt as bad as the one on the right but there is still blooming, Contrast is meh so they kinda represent each other in some type of way and with OLED having insane contrast it fits more with the picture on the left... Funny how old videos still relate as of today but the take away is i feel like contrast is what really makes the difference

[@harrysvensson2610]

the divide by 0 => undefined is because you get different results when approaching 1/0 from left and 1/0 from right. 1/(0.1) grows positively while 1/(-0.1) grows negatively => they will not move towards a single point at really small values of x => undefined. Because using smaller positive values approaches +infinite while going from left approaches -infinite. And those are two very different places. But... in this case... it would be +infinite (not -infinite, and not undefined) contrast ratio because you would only use positive numbers. Meaning that you wouldn't take into account the left hand side (the negative numbers).

[@JakeTraver]

Was wondering the same thing. I looked at "Top Gaming Monitors of 2021", and they are all between 2500:1 - 3000:1. None of the millions:1. Which is how I ended up here. I'm getting this Samsung gaming monitor that is 3000:1, and we'll see how it goes.

so how does oled work with contrast ratio? blackest black on oled is off, so a million times brighter than off is still off...?

[@Cade_Squirrel]

Meh... I have my eyes on a 4K LED HDR Sony Bravia, LCD technology is the tried and true technology that we know well and understand every aspect of it meaning we can get the most out of it, and LCD lasts for years, I'm always very wary of newer technology especially when it doesn't really add that much, LCD is just a trusted technology that I can be sure will serve me well, also low input lag and high Hz

[@iwontliveinfear]

Two points: First: No two manufacturers use the same unit of measure when determining contrast ratios, therefore one brand's 3000:1 could actually be lower than another's 1000:1 Second: OLED isn't really "there" yet, and LCD contrast ratios still suck compared to my plasma display. Which, thanks to pixel shift has worked flawlessly for 5 years without any image retention. So what if I can't run at 4K, further than a foot away you would need an 80 inch panel to really tell the difference between 4k and 1080p.

But OLED is still infinite, since the pixel goes down to completely zero black (turned off) then the difference between the black pixel and the on pixel is infinite. So what's with the 10M:1 contrast ratio? There shouldn't be a number to define it, It's ∞.

[@RoboticNerd]

Technically with oleds it is an infinite contrast ratio. A fully lit pixel is infinitely brighter than a totally black one. Infinity is weird. If you think about it, even 10 is infinitely bigger than 0 when you're thinking about it in this sense as 0 cannot be multiplied to equal anything but zero until you actually add something to it. So any number greater than zero is infinitely larger when comparing it in this way.

[@ssamDJ]

Robotic Nerd But to get a ratio you divide the highest brightnes with the lowest. That gives you x/0 wich is undefined.

[@RushilKasetty]

A Freaking Sandwich But if you use limits, it approaches infinity, which works well enough.

my tv is really old, and i calibrated it to make it look better. but in doing so i realised the calibration assumes a certain performance that my tv didnt have. so i made my own config where i pumped up the contrast and brought down the brightness. you lose a small ammount of detail in very dark scenes but overall it makes the tv look heaps better and ulitimately made me hold off on buying a new tv

I suppose if individual pixels can be turned off, then the contrast ratio is actually infinite, though of course that could tell us nothing. It would still be infinite even if the brightest bright was barely noticeable.

Are they just arbitrary numbers which only function is to let us compare between panel types, or is reality somehow involved?
