ASUS PG27AQ 4K G-Sync Problem

Hi all,

I recently purchased one of these from overclockers. The first one that arrived had a backlight fault and was returned, but I've been sent a second which the backlight works perfectly.

I have a different issue however. Very occasionally perhaps once every hour or two hours, an artifact will appear on screen for one or two frames. It might be a block of multi-coloured pixels or a line of grey dots. I do not have time to get a screen shot and it is difficult to predict when it may occur.

Does anyone know what this might be?

I also have a similarly specced ACER XB280HK (TN instead of IPS) which does not have this problem on the same hardware.

No ideas?

It seems to do some sort of refresh or switch when it happens... which I know sounds very vague..

Problem is that this monitor is very new, with few owners as yet. I'd personally try another DP cable, see if it fixes it

Fair enough, I'll give that a try. Thanks.

I had some red artifacts on my monitor recently, thought the GPU was giving up, turns out it was the DVI cable i was using. Swapped it out and all was fine

So i'd say definitely give another cable a try.

Yup, never hurts to start with the basics

Thanks chaps. I have used a different displayport cable and it is still doing it occasionally, even when just on desktop.

It's a rectangular shape that appears for probably 1 frame and then disappears, or a few dots in a line. Does anyone else have this screen that could say whether they are getting it too?
