I am here with the focusing issue; seeing glows around high contrasted elements and feeling as colors were turning metallic. At least on bad hw/sw.
For me mainly all the displays are bad that's produced after ~2017 when it comes to gaming monitors (tried only those), thus I'm forced to stick with some old dumb displays. Other PC HW stuff doesn't matter, nor SW-wise i.e. the kind of Windows builds, Linux, driver, etc.
As for games, there are AAA titles, where this strange kind of rendering is used and visuals are feeling like the above mentioned, again since the magic date of ~2017…
Interestingly then, business monitors/notebooks at my work are just working without any problem, no matter again the SW side, like OS, driver, whatnot.
As I mentioned in another thread before, the iphone 13 pro max is working for me flawlessly after turning down the white point in the accessibility options. Tried the same method for games with Reshade, so the final result in the rendering chain gets the white point reduction, but no luck.
Long story short (for my case at least); something happened around 2017 and noone knows/tells what.
This kind (or part?) of "technology" seems not to be present in business, only in entertainment & co. And it is well… hidden away(?)
