LG 34UM95 lagging

post #1 of 11
Thread Starter 
I currently have:
CPU: i5 2500k
MOBO: asrock p67 pro3 b3
8GB ddr3
GPU: gtx 570 1280MB

I have bought the 34" LG 3440 x 1440 monitor, and waiting a week until I get GTX 980Ti - the thing is that right now with my current setup the screen seems to be very laggy on the desktop in idle - moving a window with a mouse causes a lot of stuttering.

Also movies in 1080p on youtube seem to be worse quality than on my previous full hd screen.

I can return back my monitor during first 30 days. Is my GPU the cause of it? Will it get better with a better GPU?

Are you using the latest drivers from Nvidia for your GPU?
What is your resolution and refresh rate set to?
Have you reset the default settings on the monitor?
Connected through DP 1.2 or some other connection perhaps?
Did you install a driver for the monitor?
Was your previous monitor 120/144Hz?

Yeah, in windows 10 settings I have 30 Hz set as a monitor refresh rate. I can't change it, that's the only value in the select field. What's wrong?

This is what I suspected.

Are you connected via DP or HDMI? (You should really be using DP for that resolution / refresh rate).

I connect it via HDMI, with a DVI converter to the computer (mobo - asrock p67).

You could try CRU. All you have to do is add a custom resolution with your selected refresh rate and reboot.

HDMI might introduce some more interface lag, too.

This won't help. His connection is the issue.

3440 x 1440 @ 60Hz is too much for HDMI 1.4. to handle, hence why you are stuck as 30 Hz.
As I said before, DP 1.2. is the correct choice for such resolution.

His card doesn't have display port i don't think. Try 1080P for now until you get your 980ti. If it runs fine at 1080p, it should run great at 1440p over display port.
It's a better idea to have your system in order before you buy a monitor, so you can test the inputs you will be using and all it's features correctly before the return period.

Also hdmi to dvi converter isn't an optimal solution.

Yup, after connecting it do DisplayPort input everything works perfectly! I just had a plug put into my display port, I've never used it before.
