Sometime last year I had bought a LG 27” Ultragear 27GX700-A that was 280hz and a great 1440 monitor but then I started experiencing issues after while where my games would no longer natively launch in 1440p but rather 4k and it caused me to lose a lot of my fps in games like marvel rivals, valorant or Genshin impact which would struggle to run smoothly. And the monitor seems to have dead spots too. I am personally really interested in Dual Mode monitors such as the 4k 240hz and 1080p 500hz which sounds perfect for watching movies or anime, then switching over to 1080p when I want to play my fps games but I’ve heard some of this monitor give a sort of blurry effect when downscaling to the lower resolution I am just not sure if it’s worth getting this type of dual mode feature or just sticking to getting a 1440p 500hz. Opinions are appreciated since I am probably going to spend anywhere from 500 to 1000 dollars.
