Great monitor. Have driver. It won’t change your performance any, but it does add color profiles for printers and such. Zip is 500KB, too large to post. PM me. for it. Does iiyama no longer offer the driver? http://www.iiyama.com/
This monitor sold for about $1100 USD when it first came out. It still compares well to the newer models for image quality, and exceeds all it’s specs. Fine for games and movies too. It originally also came with “Pivot” software that allows pivoting the screen to portrait mode, but it consumed huge amounts of CPU time.
