Excellent Frames for the Dollar - If you are chasing frames and don’t care about 2k or 4k resolution this is a great option! The picture quality is very nice and even budget-friendly builds can crank out 280hz with this monitor. Honestly works great out of the box, comes with lots of features you can tweak for your preferences if you wanted. This product goes on sale often, catch it cheaper and get even more bang for your buck. Some people think 24” is on the small side, you won’t notice when you’re locked in anyways but you can get a 27” version of this for just as great a deal.

Great Monitor - Colors are vibrant and crisp. Refresh rate on it is also really nice. I don't do competitive gaming or anything, but the video's I use it to watch all look amazing and well detailed.
