4K 120 hz HDR low res text on OLED806?

Hi!

I have noticed recently that while 4k HDR and 4k 120 hz work well separately connected to my pc (via a Maxonar certified 2.1 cable into hdmi 1) if I go to 4k 120 hz and hdr enabled in windows 11, all the text becomes slightly lower resolution, almost as if anti aliasing isn’t turned on properly.

Is this a bandwidth limitation or a limitation with the panel, or is something wrong on my end?

thanks,
sen

It's because this tv does 4k 120hz at half vertical resolution if you have selected hdmi optimal (auto game). If you want full 4k resolution at 120hz you need to select "Optimal" but you will lose VRR (and ALLM).

The SoC isn't quick enough for Freesync/VRR at 120hz/4k so this is the workaround Philips/TP Vision chose. Sony TV's and others with the same SoC use similar workarounds. It's a silly thing honestly. Problems like this won't be solved by firmware updates and are just a problem with a 'new' technology.
