My 2K monitors work in 4K. Is it safe to leave it at 4K

I have 2 x Philips 328P6AUBREB/75 monitors that are supposed to be 1440p monitors @ HDR 400.

I just moved my PC back upstairs where it lives in winter and I was looking at the display settings and noticed 3840x216op was listed as a resolution. I figured I would try it expecting a "frequency out of range" error, but it works fine.

Checked the monitor settings, and the model # is definitely correct.

I thought maybe it was down scaling but the UHD image is definitely a lot smaller than the QHD image.

Is it safe to run them at UHD when it's specs say QHD? Am I likely to burn them out or cause other problems?

My GPU is an ASUS RTX 3080 Ti 12GB connected via display port cables.

I do recall I had problems with my original purchases (edge bleeding), and these are warranty replacements, but the model numbers are the same...

Why wouldn't it??

The model specs say 2560 x 1440 display panel.

Looks like they replaced the panel with 3840 x 2160.

You could increase the scaling a bit if things are too small.

Those are physical pixels of the screen so there will be no problems.

Awesome! Free upgrade from QHD to UHD.
Only thing I noticed in UHD was max freq is 60hz. In QHD it's 75hz.
