Is there a way i can get rid of the floating "Out of sync" OSD window that my monitor displays when i go above 80hz?

the screen itself can display up to 115hz without skipping nor corruption (starts corrupting at 120hz-ish), but when i create a resolution above 80hz the damn window will pop up after 4 seconds and stay there, even if the image IS displaying properly (which it is, tested it and it doesn't even skip frames. almost as good as my good old 144hz gsync screen).

i'd be happy as a tree with 95hz. 80hz on the other hand, is a bit choppy for someone used to 144hz :\ i mean, it's far better than 75 already, it's actually okay. i won't die if i can't increase it further, but the more hz the merrier.


my screen is a lg 34um68 (2560x1080 ultrawide screen that's 75hz freesync from factory).

it's so frustrating to see it working at 100hz but not to be able to use it like that because of that stupid window blocking the center of the screen
so far i've only talked to people who are even more clueless than i am about this. here's hoping a wizard lives here and helps me out

ps: it's on display port 1.2. using a rx480

Any such option, if it exists, would probably be hidden in the service menu. But don't get your hopes up. Even if you knew the monitor button sequence to even get into the service menu, it might not do anything. You could try enabling "burn-in mode", but there's a 99% chance that wont stop the error. That might just cause the monitor to display some pretty RGB colors when a disconnected input source is chosen (on many monitors, this is HDMI).

That error is the monitor complaining about the timings.
The Benq Z series monitors do the same thing when you give it timings that the firmware doesn't like, but what the scalar can still actually display, so it "warns" you that the timings are improper, but doesn't completely lock you from use. For example, 1024x768@85hz, well, ANY 85hz display scaled refresh rate that is LOWER than native (meaning: not GPU scaled, and lower than 1920x1080) will show "Out of Range" even though you will still get the display. You can "get rid" of the error by pressing an OSD button to select the same input source you are currently using, which will cause the error to disappear after you select the input source currently active---then you can use the screen without any overlays covering it--until you press ANY osd button again. Then the error will reappear. Of course you're locked out of all OSD adjustments like this.

See if you can press a monitor button and select the same input source (DVI or displayport) and make the error go away.

Otherwise you'll have to bug LG's engineers for a "test" firmware that won't complain if the monitor can display an image. But you have a 0% chance of them even listening to you unless you are friends with the firmware engineers...
