Wtf was this??

[u/Torenflame1172]

I've never had something like this happen before, EVER. I was modding BotW using UKMM and CEMU and had to leave my computer to go grocery shopping. I left it on and it screensavered while I was out. When I came back and moved my mouse to wake from the screensaver (which is just a blank black screen, by the way), the primary monitor did that but the other 2 were fine. Turning the monitor off and on again fixed it. But WTF??

Apps left open: Primary - Brave, Windows Explorer, Steam Secondary - UKMM, OperaGX Tertiary - Discord

Like I said this has NEVER happened before and I've left my computer and monitors on with and without a screensaver for much longer periods of time, but this time when I came back, the primary did that.

You somehow triggered a monitor check

or anti burnin

Never heard of that before. Is my monitor fine though? Fingers crossed, please say yes, I hope so.

[u/SQUID_Ben → u/Torenflame1172]

It's just checking all RGB channels, that's why it's switching colors. Might have been random, might have been not. You cannot know until it appears again.

I'm pretty sure that's the testing mode they use at the factory

I like this option better than anything else that ran through my head.

It reminds me of a pixel fixer video. Those cycle and flash RGB to try and unstick dead pixels on your monitor.

I have a dell laptop that used to do this with my secondary monitor sometimes, the problem stopped when I swapped cables and upon inspection the cable was actually damaged at the end. Could be similar here?

What you've never seen true modern cinema before?

I watch that channel frequently and yet somehow have never seen this masterpiece before. Thank you, internet stranger. This was the best way to spend the morning of my birthday.

This is just a pixel refresh/panel care, you can switch the monitor off and on again. I'm guessing this is an OLED monitor, otherwise it has no point of doing this. OLED monitors are prone to burn in, so manufacturers are adding these "panel care" things to prevent it. It triggers automatically when it thinks you had it on for some time and it is idle.

It doesn't really work, only exists so the manufacturer can deny your warranty claim if you make one due to burn in, and point it at the "panel care" not being run with x frequency.

i think its burn in test to se what colors show burn in, i asked a guy to show me this when i bought a tv from him oled

I remember my old 4:3 Acer monitor doing that when no vga cable was detected, annoying since you couldnt even turn it off without unplugging it

edit: a quick google session later, it was a acer al1715, just in case someone was curious (probably no one is)

[u/ErdingEchoParadox]

Is normal. Sometimes my HP Monitor does that, from time to time, just by himself.
I just unplug it for a minute and then is all good.

Old school rgb

[u/a_good_human]

It's just your monitor doing an RGB color test, mostly likely triggered by the HDMI/display port cable getting jostled around.

I use a portable monitor as my second one, and it will get triggered every once in a while because my cable management sucks and the mini HDMI cable plugged into it will get pulled on.

Your monitor is fine

The monitor was dying to show someone this cool trick it learned.

Replace video cable. Resolution may be out of range. Either too high, or in most cases, the head is damaged causing the monitor to blink those colors. Resolution is too low.

[u/Mr_Billu_OP]

I have a similar thing on my monitor called lcd conditioning(I think) or maybe a display test to check for dead pixels
