Before I drop some money on a 4K monitor, I thought I would ask what brands people have had success with. I realize there are duds with every brand, but I thought I would ask for advice before spending money on this. I'm looking to game with it. I know I would also have to upgrade my video card. I also realize that once you get to 1440 or 4K, you start buying G-Sync or Free Sync monitors for NVidia and AMD, respectively. Right now, I'm not deciding between NVidia or AMD. If people like the G-Sync monitor better, I can go with NVidia...if people like a Free Sync monitor better I can stick with AMD (what I have now). What sort of things do I look for in a good monitor? I think 5ms response time or less is good for gaming, but beyond that, I'm not sure. Thanks for any responses, guys. I really appreciate the help.
