For gaming, the best experience I have had all these years with PC monitors are from Asus. I dislike LG and Dell.
Then again, the best LG is better than the cheapest Asus. It's really what you are looking for. I never buy monitors online, I usually go to a store myself and compare. Whenever this happens, I usually go home with an Asus. They really focus on the gaming community nowadays.
One thing, NEVER buy a television monitor and use it for PC gaming! It's not made for it and just looks very bad.
