Just finished the 3rd major upgrade on my 2009 Mac Pro. This time I upgrade my 27" ACD to the Samsung 49" CHG90. It's a ultra wide monitor (32:9), effectively joining two 27" 1080P monitor together without any gap. Even though the resolution may be considered a bit low today, but it work flawlessly. Downgrade from 1440P to 1080P make everything looks larger on the screen. When I upgrade from the 24" ACD to 27" ACD few years ago, the very first thing I realised is that even the monitor is bigger, everything on the screen actually look smaller. And since 1440P is not "retina", if I use it to run 1080P HiDPI, everything will looks blurry. Eventually, I often lean forward to read the screen. This is not comfortable at all. But now I can sit back, relax, and still able to read everything clearly on the screen. It's a gaming monitor, 144Hz, so, mouse pointer movement or scrolling etc looks very smooth. And I like the back light very much as well.
