I recently built my first PC and purchased 144Hz 1080p monitor with it for playing games, however the colour on it is not very good and I also do a lot of video editing and am looking for a 60Hz monitor that is 1440p and has very good colour accuracy. My GPU is a GTX 780 and I am not sure what is the highest colour bit accuracy that it can output I wouldn't want to get a 16 bit per channel monitor because I am sure that the GPU is simply not capable of outputting colour at that accuracy.
Does anybody have any suggestions for a suitable monitor as I am struggling to find one. (preferably something under £1,000 ~ $1,660)
