MAG 273QP QD-OLED X24 - HDR Issues after running Panel Protect

[chrisgarso15bc02e9]

I've had the monitor two months and yesterday I got a prompt to run Panel Protect, I had seen this once before and this time I chose to run it. It completed after a few minutes but ever since then HDR does not appear to be applying correctly and looks closer to (and worse than) SDR.

HDR now looks a little washed out and black levels don't look correct. The issue is most noticeable when in Windows (presumably when it tries to adjust SDR content for my HDR display) where dark areas of images appear too bright as if the colour tone mapping(?) is wrong. Native HDR content doesn't present obvious issues at first, but it no longer looks much different than SDR and there is a bit of a bright haze over everything. I've noticed this on both my PC and Consoles. Turning down the peak brightness/paperwhite setting does not help as it just makes the image too dim without really improving anything. Currently my image looks a bit better with HDR off, but before this issue HDR looked great everywhere.

I've tried updating the firmware to v.120, proceeding to remove the power cable for a while, resetting the config in OSD, trying different cables etc, nothing has helped.

I'll submit a support ticket, hoping there's an easy fix but it's looking unlikely.

I've started the RMA process for this and wanted to add a little more info since I've linked this thread in the RMA form.

After the change in the HDR output occurred, I was questioning whether the Panel Protect process actually could have re-calibrated things and actually fixed an issue that was previously there. There's not an obvious issue in all cases, but after continued testing I still feel things are just not quite right - everything's just a little too bright.

Another reason I started second guessing if there was actually an issue is because HDR videos on youtube for example look fine, but I'm thinking that's because of the hard-coded tone mapping. So my suspicion is the monitor is no longer communicating correctly when it comes to more dynamic content, like the EDID/EOTF data or something on the monitor is not correct.

Here is an example of what's occurring (it's a bit exaggerated here due to using a phone to capture, but it gives an idea):

and here is the source image:

This image appeared completely fine in Windows before, and it also looks fine on my older HDR10 monitor, but the area between the rocks and other areas of the image now look overblown and low quality.

If anyone seeing this is also on a HDR display and see's issues with this image, please let me know . Thanks.
