Backlight uniformity at 144Hz

I'm on my third 1080p 144Hz monitor in my hunt for something acceptable. The first 2 were Acer XB241Hs that had a weird curved deformity to the backlight. My current one is an ASUS MG248Q that is actually really good except for some lines 1/3 and 2/3 of the way up and some light on the edges. I can only notice them in really really dark games. The lightbleed is minor and acceptable to me.

Does this look acceptable or should I keep trying? I can just return it to the store, so it isn't a massive hassle.

144Hz, 25 brightness: 1 2

144Hz, 100 brightness: 1 2 (brightness didn't help at all)

60Hz, 25 brightness: 1 2 (looks excellent as far as TN goes)

It always seems like these things pass QA at 60Hz and then look off at 144Hz.

I also have a VG248QE as of Sunday with similar issues. So I guess I'm on my 4th monitor now that doesn't have perfect backlight at 144Hz but is perfect at 60Hz and almost perfect at 120Hz.

Would that mean that you think I could do better with the uniformity?

I looked at the AOC as an alternative to the Acer Predator before I got this ASUS. I kind of worried that the green bar might annoy me. I'm really not sure why they went with that design choice. I'd consider trying it out, though.

I had the PG248Q and it was much better, but not great.

I have the AOC G2460PG and so far, it's far better and I would *highly* recommend it.
I have the same aoc monitor it is great i two give it a thumbs up.

Edit but the amd freesync model, the g2640pf

If you want to get rid of the blacklight bleed problem, you need to go VA.

IPS will almost always have it, and TN will nearly always have it as well. Honestly would recomend not even picking up a TN if you could avoid it, hell I would even say that going for anything less than 1440p would be a mistake. But if you are going for 144hz for some quick FPS action, than by all means.

Really you are just going to have to demo units until you get one you are willing to stick with. I know they make VA panels that are 144hz 1080p in your price range, so I would check those out. VA is not as quick as TN, but they have gotten much better than they were years ago. VA has the best Blacks out of all monitor tech, so if you like good black levels (and I know I do) I would atleast think about it.

Yeah, my AOC G2460PG has great uniformity.

The green stripe only looks like it would be bright and distracting because the lights used for the product photos are extremely bright which make the stripe look like 100 times brighter than it really is. In reality, you never really see it unless you look directly at it.

In person, it looks great.

I'm aiming for 144Hz in most games, not just competitive FPS, even though that is a very large part of my gaming time. I can't achieve this with 1440p unless I sell my 1070 and get a 1080ti (which I admit is tempting).

It looks like all the VA 1080p monitors are 27in (uhh?). Seems like a strange decision unless it is a technology limitation.

I was playing most of my games at 90-160fps on a single 290 @ 1440p. 1070 can power through those games no problem. Honestoy 1440p is a big step up from 1080p in terms of desktop space. Honestly couldn't do without it. Actually just made the jump to 3440x1440 myself, 290 was still getting good frame rates for the most part, but just picked up the 1080 to bring up my min frame rates.

Not all TNs are bad, just shifting through all the crappy ones takes a lot of time.

I'm guessing you had to lower settings, which I don't want to do. A lot of modern games push the 1070 down to 70-80.

Naw I max games out other than AA. Which is not really needed at that res on most games.

Games like Overwatch was in the 90s+ for me, and that is maxed out at 1440. Same with BF1 (now if you start going past 100% res scale you will have problems).

Though Overwatch, BF1, and CSGO are the 3 online FPS games I really only play.

The new masseffect on the other hand takes more of a beating on the 290 at 3440x1440, 70% res scale is a must.

an overclocked 1070 will push most games in the 120+ FPS range even at 1440p.

I've just been going off benchmarks. My only personal experience right now with a game that actually pushes my card is For Honor which ran at like 100 fps maxed at 1080p. I don't want to imagine what it was at 1440p. My card is clocked at 1911 MHz, too.

Also remember that because 1080p is such a light res on Modern GPU's the CPU is going to play a big role in overall Frame rate. Along with high speed low latency RAM.

1080p today is like running 1280x1024 6-7 years ago. So CPU can make a 20fps difference real quick. On anything but the most GPU dependent games these days,

Also a Monitor in an investment. I know I use mine is used for more than a single GPU generation. Granted its been nearly 5 years since I used a 1080p monitor as my main gaming display. been using 1440p and now 3440x1440. Even my old 7950 was able to handle gaming at 1440p at a very playable level.

I think, no matter what, I'm getting a new monitor in a few years and end up selling whatever I buy now. I want IPS, but they don't make 1080p 144Hz IPS and 1440p 144Hz IPS is way more than I want to spend. IPS should go down in price over the next few years. Actually, I'd prefer to have OLED 120/144Hz, but they don't even make them yet.

I just want a monitor that looks good and will handle 100+ fps for games without lowering settings. Maybe I'll end up with this one since it looks fine in every game except super dark ones.

It's not that bad compared to mine.

144hz
1080p
24" Curved VA
