Dimming in and out??

Zeebedy · 8 May 2025 at 17:05

Hey guys,

I have noticed (unless im seeing things) that my monitor seems to get dimmer, then brighter, then repeat this.. its very subtle and wonder if its a setting or what not??

My monitor is the LG UltraGear OLED 32GS95UV-B.

Can't remember the terminology, but think OLEDs do this for burn-in protection. Certainly my LG OLED 42 TV does, one of the reasons I have stopped using it as a PC monitor.

I haven't noticed the 2 smaller MSI OLED monitors I replaced it with doing it so. (only 4 days or so use so far)

ahh, ok, makes sense..seems more noticeable (not by much) when loading google on the browser with all that bright, white real estate!

Might be worth reviewing settings, on the TV (C2) it needed the service menu to disable but think on later models it was handled differently.

On the MSI OLEDs there are a load of “Care” features, you may have something you can modify. I have all mine on I think, and they are unobtrusive other than the cycle it wants to do every 4 hours of use (which I am letting it do)

yeah, i will look into the settings.. not too fussed about it, least its doing its job..yeah, on my old OLED I sold here in the MM was wanting to do a "screen clean" every four hours.

probably one of the oled care features. Look for one called screen saver or something

Possibly it's the power saver feature.

yeah, I think its along those lines, the amount of faff the monitors that are OLED do to save themselves, unreal..

When I bought my LG OLED monitor some of the reviews said to turn off the power saving feature as it was just too aggressive.

Most OLED displays have an ABL (Auto Brightness Limiter) in their settings that is either possible to be disabled (but hidden really well or needs specific ways to access), or permanently on.

Typically speaking, it's most aggressive on HDR settings it is not native at. The AW3423DWF for example, can have full screen white no problem, the fan will kick in eventually, but it will be fine with HDR set at HDR400 True Black even with full screen white. But the moment you attempt it at HDR1000, the ABL will kick in really quickly and turn everything grey and washed out to prevent screen damage.

If you can't find the setting to turn off (as not all displays permit you to do so), you can try and locate the no ABL version of HDR on your display and swtich to that.

I dont think it is too intrusive as after a gaming session usually it needs to do its thing, so i leave it too it as i power down the PC.
