I was wondering if there is a way to stress test a IPS monitor to check for dead/stuck pixels. I’m asking this because here in my country the return period for products is 7 days only.
Last week I bought an ASUS Proart monitor and after a couple of days found 3 stuck pixels. Given this return policy and manufacturers warranty for defective pixels, I consider myself lucky because if the problem occurred after 7 days, I would have been stuck with the monitor.
In the last 20 years I had about 6 monitors and never had this kind of problem and after reading some local forums a lot of models seem to have this issue, so there it is my motivation for asking the question.
So, is there a way to test for this kind of things? Is it a waste of time?
Thanks in advance for any insight/advice you guys might have
I’ve never heard of a “stress test” for such a thing. You can only really just check for dead/stuck pixels with solid black, white, green, blue, and red images.
If stuck pixels are present, then rarely a rapidly changing image placed at that spot may unstick them, but I wouldn’t hold your breath.
Yes. I had two monitors in 2022 getting stuck pixels in a matter of 48 to 72 hours after purchase. I tried Jscreenfix for hours and didn’t solve anything. Since you’re in the narrow return window is better to get a new one that’s not affected.
I thought that maybe the LCD panel industry could have some QC test or maybe leaving a white screen for hours could induce those faulty pixels to show up faster.
I’ve tried the Jscreenfix fix for hours on the ASUS and it didn’t work.
Yeah, I’ve already returned it. Going to try my luck next month. If those faulty pixels show up very early, on the next one I’ll try to leave the monitor on for 5-6 days and see if they show up before the return window.
While there are programs that switch between pixels, they’re more useful for trying to get rid of screen burn-in or stuck pixels than trying to jolt dead pixels into working. With the way desktop TN & IPS monitors have gotten larger, the odds of stuck or dead pixels goes up a fair amount past 24".
Generally you have to use the monitor about 2-3 days, I’ve had pixels get stuck at that point than out of the box. On a recent monitor I was able to massage two stuck pixels into working but that may have been more related to how the monitor was packed at the factory as it had a suction cup grip mark in the area.
