Reducing display lag. ( 4K! )

[Evil Ninetales]

Ok first things first. My hardware.

CPU : AMD FX : 4300 quad core @ 4.50GHz
GPU : MSI Radeon R9 270X Gaming Edition OC 4096MB GDDR5
Monitor : Samsung U28D590 ( 4K ) display. ( Using Display port cable 3840 x 2160 @ 60Hz )
RAM : 16GB DDR3

The problem

Ok so the problem I have is my new 4K display ( which claims to be a gaming monitor ) Has horrible input lag. By horrible I mean it takes almost an 8th of a second to respond, this may seem like nothing but it's devastating for FPS gaming. I can't aim with it and I get seen by enemies before I see them.

This is the monitor and the place at which I bought it.

Outside gaming it's beautiful display and the extra space works wonders for source filmmaker or artrage.

I have tried everything I can to fix this and am close to tears of frustration with it. Games look stunning on this but are impossible to play. I have updated my gpu drivers, Installed the monitor drivers direct from samsung website and have tried other monitors ( None of which have any display lag. )

I don't know what could be the cause. Is it possible the display port cable could be the problem? I don't want to go out on a limb and buy a new cable if it's impossible that it could be the fault.

Any help on this would be absolutely amazing. Thank you in advance.


I think the most frustrating part is that I can't find anyone else who is having this problem.

Do you even realize how much more your graphics card and CPU needs to work pushing 4K resolution compared to 1080p.

3840x2160 = 8.29 million pixels
1920x1080 = 2 million pixels

4k is basicly four 1080p monitors.

You have medium range graphics card and below medium range CPU with weak cores, stick with 1080p.

During gameplay GPU temp is 57, GPU usage is average 85, Frametime keeps jumping between 80 and 130.

Honestly!? You didn't read any of my previous comments did you?

Firstly I know what 4K is, Secondly as I have said NUMEROUS times previously I have way over 60fps in "THE GAMES I PLAY", I don't play top of the line games. Thirdly this problem happens still when I set monitor to 1080p too so stop blaming my GPU's capabilities please.

I don't know much about frametime, can't find much info about it. I read that it is like the time it takes to render and display a frame, or something like that. Yours seems super high. Mine jumps between 2 and 8. Not sure what causes it, or how to fix it, since i never had any trouble with it.

I also read that normally for a 60hz monitor, frametime should be around 16.

Well I will look it up and see if I can find a reason for it. Thank you very much for taking the time to reply to me, it's very much appreciated.

are you using a hard disk drive with 5400rpm to 5900rpm?

I'm using two 128GB SSD's

1x Samsung SSD 840
1x OCZ-Agility3 SSD

from your screenshot, it appears you have a ping of 64ms so basically no internet lag...
i wonder though what is the reason behind the 'blurring' of the ping value with something else.

what is the latency of your 16gb memory modules?

it could be the monitor/tv
put it to gaming mode or disable any frame blending effects on it

We were disappointed by the high lag of this screen as well, as although response times were pretty decent, this could be a bit of an issue for competitive gaming.

Found in conclusion.

I guess I'd better stick to my old monitor for gaming then

Evil... It really was frustrating just reading this thread and the fact that nobody understood you despite your rather lucid explanations: Blaming your card, and various effects settings... sheesh, Rumple was particularly unhelpful, I thought.

I know they were just trying to be helpful, but it does more harm than good to offer opinions backed up with apparent confidence on things one has only a passing knowledge of. I purchased a Philips "gaming 4k" monitor with horrific Input Lag. The shop claimed 1ms and at first refused to replace it until I got permission from Philips directly. I replaced it for the Asus 28 which has only 11ms of delay... I can now destroy anything in Elite Dangerous @3840x2160 res.

Once you try 4k gaming, it's hard to go back... It really is GORGEOUS!
