3000:1 vs 5000:1 contrast ratio, big difference?

post #1 of 22
Thread Starter 
Wondering for those who've had monitors with static contrast ratios in those figures, is there a noticeable difference between the two? I'd be coming from the "norm" 1000:1 so i know i'd see a big change anyway.

Much, much deeper blacks. 5000:1 approaches close to decent CRT levels, but remember CRT's don't have backlighting, so the contrast ratio of a CRT can't really be measured Overall, probably not as good as a CRT with a decent tube properly calibrated (which can give TRUE blacks) but deep. Some said that shadow mask CRT's could give up to 2000:1 contrast ratio (as measured on a 2000:1 LCD) , while a properly calibrated aperture grille CRT could exceed 10,000 (this is assuming you had an LCD of this type capable of it)

Contrast ratio is the single largest aspect of image quality. Take of that what you will.

Fully agreed and sig worthy.
Shows why a properly maintained CRT with a decent tube can't be matched by any current (at least consumer level or gaming) LCD.

But let me get a bit off topic and ask:
How do laser projectors fit in all this?
Don't they have infinite contrast ratio due to there not being a true color gamut and no backlighting? (the black level is based on the lighting and the projection layer (forgot what its called) used for the image?

Probably not.
https://en.wikipedia.org/wiki/Human_eye
"The retina has a static contrast ratio of around 100:1"

http://www.practical-home-theater-guide.com/contrast-ratio.html
"A higher contrast rating implies a device has greater ability to display black with a deeper shade of black instead of just dark gray with respect to its brightest whites. A home theater projector with a contrast ratio rating of 8,000:1 is more capable of showing a dark subject than one with an 800:1 contrast ratio. But the difference in performance between the two would only become apparent if projection takes place in a completely dark room, one in which is there no light other than that of the projected image.

Equally important is that the eye would not detect a 10 times improvement in contrast performance between these two projectors. Rather, the perceived difference in image performance between these two devices would be just marginal and detectable only if the room is in total darkness.

Marginal, because the eye contrast sensitivity is not linear. While a difference in a contrast ratio of between 10:1 and 20:1 will be definitely distinguishable and a difference between 100:1 and 200:1 as clearly visible, the eye would see the difference between say 400:1 and 800:1 as a minor change. And anything above 1000:1 may not be visible at all.

And it is detectable only in the total absences of ambient light because as we will see further in this article, complete absence of stray light in a room is critical when it comes to contrast performance. This is a rather rare situation in everyday life unless viewing takes place under a controlled environment, such as that of a dedicated home theater with black painted walls."

This fits my experience. I found IPS colors having more impact onto the picture quality than VA contrast, but I can imagine why it is subjective -- after all some people are color blind!

Whoever wrote that is smoking crack. Is this person writing like we are all viewing our screens in office spaces with mind blowing florescent lights bombarding us?

Most people watch movies or plays computer games in dark or dim rooms. Or those like me with bias lighting. It doesn't take a rocket scientist to know that you don't want ambient light shining on your display. 1000:1 contrast ratio is pathetic.

Now add on a horrendous black point, back light bleed and IPS glow, you can see why IPS would be among the last to pick for image quality. IPS is only suited for blasting bright images in a bright room, otherwise there are far better options.

So what is the best panel for the gamer that wants tight pixels and a beautiful display? 60hz is fine with me as long as there is minimal blur.
Watching movies from afar and gaming up close are terrible on my screen.

Sub $300 would be nice.

Those "expert" opinions ("contrast is the most important thing") really crank me up. According to them CRT TVs and plasma is the best thing since sliced bread. It is laughable how unsubstantiated those claim are. Consider CRT display or plasma TVs which is 10 years old. A notorious problem for such device is image retention. Therefore, 10 years old TV black screen is not really black, but renders some logo burned out over the years, and often this logo is visible even over normal picture (not just uniform black image). OK, there might be no distinguishable logo, but the screen would still suffer from burn as a whole.

Certainly, the image retention of 1 year old device might be not necessarily immediately obvious, but it is just 10 times smaller. What does it mean in the context of our discussion of contrast ratios 1000:1 and above? This means that you are looking onto square #1 at
http://www.lagom.nl/lcd-test/black.php
(If you don't distinguish it from the background, it is most likely room condition, and not your monitor). Imagine, that you have 1 year old plasma or CRT screen; sure you would be having troubles to see this square because of burn in!

To summarize, be aware that video world is not much different from audio, and audio world is filled in with audiophiles (often called audiofools). The last thing you want to listen to is an opinion of audiophile.

First time I've heard "audiofool."
So when you say "often called audiofools", well I don't believe you.

It's true that as you get highend there is a decrease in difference between quality but it doesn't mean there is no difference.
It's very easy to tell a cheap TN panel from a good IPS panel, just like it's very easy to tell a cheap pair of headphones from a good pair of Sennheisers.

You come off as very rude and insulting to those who take pride in the quality of their purchases.

Let me make my question more precise. When discussing merits of audio equipment (e.g. "do all amplifiers sound the same?"), whom do you believe: audio enthusiast or electrical engineer?
