I bought this monitor for playing first person shooters on a console semi-competitively (Game Battles, MLG gametypes, scrimages, sweats, etc.). Halo, Call of Duty, Battlefield, and mainly Destiny. From what I understand, this is a sub-par monitor for PC gaming, as high-end PC gaming monitors go upwards of 144Hz and beyond. But for a console, with all games being kept at 60FPS or less, I figured this was a good buy based on the specs. Good size, under $200, and low input lag.
Before this, I gamed on my family's 72" Samsung TV. I did a bit of research and I believe the input lag was something around 78.9ms. This is around 7-9ms (it's advertised as 1ms, but you have to consider actual lag from the console to the monitor). I pulled it out of the box and it took maybe 30 minutes for me to figure out all the settings and get the brightness and balancing and things set up. I plugged in my Xbox 360 (yes, 360, screw the Xbox One), and started playing. I didn't notice a difference from the TV I was used to. I played quite a bit, and more of my shots started to hit and my movement felt a little better, but I chalked that up to a placebo effect.
Then, I went back home for the holidays, taking my 360 with me and plugging it back into the 72" Samsung I mentioned earlier. GOOD LORD. It was unplayable. I noticed the input lag as soon as I was at the main menu of Destiny. I played two doubles matches with a friend on Destiny and could barely move or shoot accurately. It felt like I was moving through jell-o. I gave up playing over break after that.
I go back to college on my ASUS, and low and behold, everything was perfect. Unnoticeable input lag, and movement and shooting was back to being crisp and precise. It was then that I noticed just how much of a difference this monitor makes. After that, I played lots of competitive matches and worked to improve as much as I could. When playing sweats on Destiny, I was making plays and hitting shots that wouldn't have been possible in a million years on a 72". I went from an above-average player to one of the top current ranked Destiny players in the world (currently fluctuating between #1 and #2, thanks to clanmates).
Is this monitor magical? No. If you're a bad player, you're not going to magically get better with this monitor. But if you're like me, play on a semi-competitive level, you're a well above-average player, and want a good gaming monitor to maximize your performance, go with this. I know BenQ and ASUS are both very good for competitive FPS monitors, and to be honest, I'm not an expert on monitors so I can't say which is better. But I can say that I am more than pleased with this monitor.
TL;DR: No problems, beautiful picture quality, near non-existent input lag, and simple user interface make this, in my opinion, one of the best gaming monitors you can get for under $200. I have absolutely no complaints thus far (three months into owning it; I will update if any problems arise). HIGHLY recommend.
