Try the Samsung S34e790c.
That has the lowest input lag of all the 34in Ultrawides. Its a VA panel.

Well, going back to 60 Hz after being used to 144 Hz is not a good idea, this is one of those things from which you cannot go back. Both 34UC88 and UC98 have very low input lag measured, so this is not a problem, you are just experiencing negative effects of decreasing refresh rate, significantly decreasing, from 144 to 60, this results with this less responsiveness feeling. I don't know if you had adaptive sync in your 144 Hz monitor, but if you did, going from 144 Hz with adaptive sync to 60 Hz without it and with higher harder to run resolution is obviously bound to be a total disaster. Also 60 Hz or 75 Hz is not too slow for PC gaming, it is too slow if you are already used to 120/144 Hz, that much is obvious.

If you like 3440x1440 resolution and this aspect ratio then wait for some 144 Hz ones coming out, I believe there are some already rumored to release in Q4. Surely Samsung is going to make 144 Hz VA ones, so if you are able to sacrifice image quality for higher refresh rate then it should be something for you.

I think it is time to write it officially in main post, there are way more reports about frame skipping after any overclock on Nvidia cards than reports about successful overclocking. Looks like some people, including this youtuber randomfrankp, got some nasty placebo effect biggrin.gif

I just got this monitor 2 days ago and have been spending yesterday the whole day calibrating it using i1 Display Pro with i1Profiler and DisplayCAL.

Results are as follow. Unless otherwise stated, all tests are targeting white point of 6500k and gamma of 2.2.

Display CAL results (100cd/m²):


High quality calibration option selected
Measured luminance: 100.5 cd/m²
Measured whitepoint XYZ (normalized): 95.4 100.52 108.98 (94.91 100 108.41), CCT = 6488K
Measured black luminance: 0.1381 cd/m²
Contrast: 727.7:1

Manual adjustments:
  • Brightness: 22
  • Red: 50
  • Green: 34
  • Blue: 31
  • Everything else default

Display CAL results (120cd/m²):


High quality calibration option selected
Measured luminance: 119.4 cd/m²
Measured whitepoint XYZ (normalized): 113.34 119.4 130.3 (94.93 100 109.13), CCT = 6532K
Measured black luminance: 0.1673 cd/m²
Contrast: 713.6:1

Manual adjustments:
  • Brightness: 32
  • Red: 50
  • Green: 34
  • Blue: 31
  • Everything else default


i1Profiler results (100cd/m²):




Large patch option selected

Manual adjustments:
  • Brightness: 19
  • Red: 50
  • Green: 40
  • Blue: 36
  • Everything else default

i1Profiler results (120cd/m²):





Large patch option selected

Manual adjustments:
  • Brightness: 32
  • Red: 50
  • Green: 37
  • Blue: 34
  • Everything else default

DisplayCAL consistently measures higher black luminance thus resulting lower contrast.

Besides contrast, manual color adjustments are needed for my monitor, which is quite different from all other reviews around to have all 3 colors remain at 50.

Light bleed on my copy is minimal compared to my old one. Only lower left and right corners have light bleed observed.

ISO 200 / 17mm / F3.5 / Shutter: 1 second



ISO 200 / 17mm / F3.5 / Shutter: 1/4 second (which is the closest to what I see in person, in a dark room)



ISO 200 / 17mm / F3.5 / Shutter: 1/6 second


Overall I am extremely happy with this monitor. It would be great if someone can shed some light on if color adjustment is needed (just in case I missed something during calibration)

hey i just got the Monitor and i am happy so far, i purchased the new rx480 for freesync.
I modded the freesync range to 37-75 which seems to work fine, but in games like Dota2 and Overwatch i get some flickering in the loading screens only while freesync is enabled,ingame there is no flickering at all.In Witcher 3 everything is working fine, no flicker in the loading screens here.
Is this normal or can it be a hardware bug?
I also capped the framerate at 74fps with crimson.
I hope you guys can help me out.
Thanks alot in advance.

this looks like the perrfect monitor- pity its soo expensive. if it frops to 600 would goodd

If you are getting flickering only in some of loading screens then I wouldn't bother. FPS tends to jump all around the place during loading screens, maybe this is a cause of this. Or maybe you have 35ish FPS during those loading screens, near minimal range you set, so maybe it is not working perfect on 35-75, I heard reports that going to 40-75 is easy and flawless but going to 35-75 introduces some flickering. If you don't need range as now as 35 then set it at 40 and be safe. But first pump up your settings and resolution in few games to get 35-38 FPS and see if you get flickering, balancing on the edge of FreeSync range is the best way to test if your range is stable and etc.

Not completely flawless, but certainly the best 3440x1440 monitor on the market hands down no contest.

If you want cheaper one, 34UC88 is very similar and it is at around $700 right now. UC98 is very expensive, but UC88 is just killing 3440x1440 market with its price/quality ratio, you get one of two the best ultrawides on the market, almost no different than $1000 one, for $700. The newest panel, newest curve, bleed and glow managed to the point when it stops to be deal breaker, great design, build quality... For $700, which is less than average price for 3440x1440 monitors. Existence of other 3440x1440 monitors is almost pointless at the moment, they are similarly priced and light years behind UC88.

Thinking about buying an LG 34UC88. Any known issues? How's the backlight bleeding? I had an older LG 34" UltraWide but returned it due to nasty yellow BLB.

Bleed/glow is similar or the same as on UC98, you are not getting anything better with IPS for this kind of screen and size. Bleed/glow is significantly reduced. From curved 3440x1440 monitors those are only two IPS ones that are free from extreme bleed issues.

As for known issues... One potential issue, to UC88 and any other FreeSync monitor, is blacking out when FreeSync is enabled. This is not constant of course, just a random fault that can happen to your unit or not, very most of them are ok, but this is one and probably only major issue that you can encounter. Here is example: https://www.youtube.com/watch?v=xuA28lD0oWU

So far I heard about 3 examples. One is this video, one is user comment for UC98 on Amazon and also one guy from Sweden got it. He posted something about it here in this thread so you may want to look at it.

I am going to get AMD card today, I still don't know if my UC98 doesn't have this issue... I will post some info about FreeSync, FreeSync range hacking and etc later today or tomorrow, finally I will be able to test all of this myself.

Well so far I wasn't able to test anything because GPU I got seems faulty and is doing some strange things, something like micro breaks in operation which causes micro stuttering. I can hear that thanks to coil whine, it stops for micro sec every few seconds, so I guess this is indicating breaks in GPU operation. Or FreeSync in my monitor is fcuked up, I don't know, but this GPU is not acting properly even with FreeSync disabled, so most likely this is GPU related problem. I already returned it and I will test FreeSync soon with other GPU, most likely RX 480.

I tried to change FreeSync range for a bit and it was working great, 35-75, I wasn't able to tell the difference between 60 FPS non-FreeSync and 45 FPS FreeSync, but then I turned my PC off, gone to work, and when I got back it just wasn't working anymore. But like I said this is most likely GPU related because it cannot handle load properly even with FreeSync disabled. I will update info as soon as I get another GPU. I just hope that this is not monitor related problem, because RMA process usually takes ages. But I won't even RMA it, I will just demand refund from retailer because if FreeSync is faulty then it was faulty at the time of purchasing which gives me a right to demand refund, hopefully they respect the law because judicial proceeding takes even more ages than RMA.

Can someone try this monitor overclocked with freesync range 40-80?
This way you would have LFC and a slight overclock.
