VG248QE 144hz Problem

[chrisf98]

Whenever I try to raise my monitor from 60hz to anything higher, everything becomes choppy and very hard to read, then the Monitor will display a message that reads "Incorrect Cable. Please use a Dual Link DVI-D cable." This is the cable I am using now, I have checked the pins and checked the GPU to assure that it is in the correct slot. Is it possible I have yet another defective DVI-D cable or is there another fix to this? I also updated the Monitor's drivers today and restarted the PC with it at 120hz.

Here is the choppiness I am talking about, the first picture is 60hz and the second is anything above 60hz:

use displayport

I know this is a solution but I'd like to not spend even more money on another cable.

At the 144Hz range HDMI and DVI-D cables lack the bandwidth to run above 120Hz and lower if you have a longer cable. A Display Port 1.2 cable will get you up to the 144Hz range but do not use cable >10Ft as the line attenuation will cause monitor sync issues.

I had a problem with my AUSU ROG SWIFT (1440/144Hz/GSync) monitor using a 15Ft DP 1.2 Cable, switched to the 6ft cable provided with the monitor and no problems.

Try hdmi cables.

Are you using another cable beside the dual link dvi cable that came with it? I have that monitor and I'm sing the dual link dvi cable that was in the box.

The cable is 6FT so I figured I'd be able to reach 120hz, but anything about 60 is screwy, even 85hz. I have an HDMI cable, I've used it for the past 6 months on this monitor and it runs 60hz very well.

I guess I'll need to look into a nice Display Port cable, figure out if my GPU supports it first. Thanks!

Try hdmi cables.

He would need HDMI 2.0 and the monitor doesn't support it. The HDMI port on the moniotr will not support 1080p at 144hz. That monitor requires a displayport cable or dual link dvi cable for 120 and 144hz.

bignastyid: The cable that came with it is completely unusable, the monitor doesn't recognize it at all, I bought my current one a week ago and just got it today.

Sounds like they sent you either a single link cable or a defective one. Its also possible the dvi port on the monitor or video card has issues.

Alright, thank you a lot. I'll look into a Display Port cable and inform myself on that.

I've looked them up before and am confused. Which one is usable on my monitor and a R9 280x GPU? There seems to be Display Port Male-Male, Display Port -VGA, to DVI... all this so I'm a bit confused.

 

[bignastyid]

Which 280x do you have?

 

[chrisf98]

Asus 280x

(awful card and support by the way, wouldn't recommend)

 

[bignastyid]

You just need a male to male cable.
