Alternatives to the LG 27GL850 with better contrast

Is there anything out there at the moment? Or maybe something down the line?

Weighting if i want to exchange this monitor with something else or keep it and sell it in the future if something better comes up. It has to be at least ABOVE 1000:1 since i don't think 800:1 and 1000:1 would be all that different (the VG27AQ measures 1060:1 or something like that but that monitor has messed up overdrive from what i hear, i don't think it's worth it). There's a new monitor by AOC that measures 1500:1 i'm wondering if this means IPS screens are going to improve in the future?

No there is no new IPS panels with better advertised contrast ratios for next year. Return the LG 27GL850 and Purchase the AOC that measures 1500:1. What monitor is the AOC that measures 1500:1?

i5 8600K OC 5.0GHz
Noctua NH-U14S
Motherboard Gigabyte Z370-HD3
G.SKILL Ripjaws v 16GB F4-3200C14D-16GVK XMP Speed 3200 14-14-14-34
EVGA GeForce RTX 2070 XC ULTRA GAMING
ASUS VG279Q 27" 1920x1080p 144Hz IPS panel G-Sync compatible

This one:

https://www.amazon.it/AOC-24G2U-BK-F...s%2C188&sr=8-1

24", no dice for me. I want 27, and i want 1440p. The 27" 1080p of this monitor has been reported to have lower contrast, which is disappointing. Seems only the 24" is the good one.

If there's no IPS panels i might as well keep the LG and try to sell it down the line. I don't think it's just the lower contrast it's the combination of that and the IPS glow coming right after trying a VA (which i hated for everything else that didn't involve contrast).

This monitor situation is really disappointing.

The only other choice you have is FI27Q. It has contrast of around 1100. That is if you want to stay with IPS.

Well, i've been doing some tests and experiments, and i think what bothers me is not the contrast, but the IPS glow. Now i'm not talking about the reflection that you get on corners which is what comes up when i google IPS glow, but this white sheen that seems to cover the entire image:


My question here would be, is this something that can vary based on "lottery"?

Because i have a 23" IPS panel that has it as bad as this LG one, and i found a review of the 23" which says the contrast is at 1160. So it can't be the contrast that's bothering me. You can see the difference here between the two:

The problem is that for a bit i had an LG 27GL650F and that one wasn't as bad as the 23" monitor.

Could it be that my actually issue with this 27GL850 is that i got one with excessive glow? Would it be worth it to attempt a replacement, in the hope i get a unit without this aggressive fog? Or is this a "fixture" of the panel type and there's nothing i can do?

Maybe i've been barking off the wrong tree here complaining about the contrast. Here's the screen at 10, 50 and 100% brightness respectively:

It can't be i'm the only person who is bothered by this, but if i google it everybody talks about either the off angle glow or the bright blacks, which is not the issue for me.

Another example. This is not my monitor but another person with the 27GL850F:

I just set the brightness to zero and it's still there. If i set the brightness to 50, which is usually what a lot of people do, it makes the game impossible to look at.

The new 1080p model with IGZO IPS.

Opus131: "White sheen" That's just contrast difference. Higher black level. Other than that it can also be caused by messed up gamma curves calibration, 16-235 vs 0-255 difference of output and expected input.
If you have some decent meter you can measure the black level and compare with data on web for those panels. But you really need a decent meter to measure accurate black level and thus contrast. Some reviews are thus quite skewed and inaccurate in black level and contrast measurement due to the meter they use.

It's always been like this, it is unlikely to change drastically.
TN <1000:1, fastest, awful viewing angles, dark glow
IPS ~1000-1200:1, fast, best viewing angles, brightest glow in corners
VA >2000:1, slowest, awful viewing angles, dark to bright glow circular all around

Dual layer exists a while but like everything else in the display market, they only implement and mass produce features that they can make a bank on. You may find great TVs with advanced panels, you may find great mobile displays on phones etc. yet monitor market stagnates on 10 year old tech.
There is dual layer with IPS, 1M:1 contrast, there is 8k 27" 120Hz, etc. It's all been done, problem is who's gonna "risk" and bring it to mass market.

IPS vs VA, as before there is tons in my thread, in the end you have to decide what pros and cons of each matter to you more. VA you get a little better contrast but often pay for it heavily in response times from blacks and viewing angles.
Display <1000:1 contrast is pretty abysmal though.

The selection is very limited no matter the LCD type and prices high for 100Hz+ for no reason other than some panels have high defect/return rate and when people spend that kind of money they won't tolerate defective panels.

Maybe your black level (= contrast for most part) is really high and then everything looks washed out and bright, which at 700-800:1 I wouldn't be surprised.

Measure your black level and check the gamma curves for each color. With a meter this should be easy but even without a meter you can check some of it.

Two new pics, one at 0% brightness, the other at 50%:

https://imgur.com/a/nHs73lE

I then set the brightness, contrast and black "stabilizer" all to 0%, and this is what i got:

https://imgur.com/a/63AFVTD

So now i'm trying to understand whether:

1) This is an issue with IPS glow or contrast.
2) It's an issue with this unit specifically and might improve if i get a replacement.

Sadly, i don't have any meter or tool but you said i can try to check it without one? How?

One more:


So just to be sure, this is a contrast issue, not anything concerning the backlight or glow.

Because when i look at very dark scene it feels like i'm getting blinded and i have to "rest" may eyes by moving towards a light source in the game, which is kinda of absurd. I'm starting to resent darkness.
