I am looking to get a new monitor, I play games on my computer everyday with a mixture of all e.g. fps, rpg etc, this monitor will also be connected to a game console; I do not do any picture editing etc. and just purely use my computer for web browsing, movies, games. Have been looking at the PA248Q because of its good colours, however I was wondering if getting a monitor with a higher refresh rate/lower input lag would have that much of an effect on my gaming experience.
Im not a pro gamer, however I do like to be quite competitive while playing, but would also like the most accurate colours.
Also what is better for gaming, 1920x1080 or 1920x1200?
Budget = under £400
