I purchased a 17 inch Uperfect display in the past, since somebody here reported improvements when connected through USB-C. Unfortunately, it turned out my Win 11 desktop computer's USB-C port doesn't support display connections and I saw no improvement when connected through HDMI.
I also gave it a try with HDMI and a "safe" old Windows 7 laptop which usually doesn't give me any trouble otherwise, but it wasn't usable in that case for me either, so I had to return it.
