Great monitor
Style: FHD 240Hz, Size: 27-inch
Quality is great. Super bright. I did buy a different mount but the original mount is good as is. The curve is nice and immersive. My games look so much better than before.

Overall a good buy.
Style: FHD 240Hz, Size: 27-inch
Got this for $150 on sale. The screen appears good and no dead pixels. I will say the speakers are not great and sound muffled (reason behind 4 stars). It seems to be a solid built monitor though and so far has worked great for my uses. Comes with included HDMI cable as well, that always helps!

Dont walk, run! (To your cart with this)
Style: FHD 240Hz, Size: 27-inch
Got this for my son for Christmas and he loves it. Big screen! The sound capability is nice for those who don't have speakers, but he usually uses a headset. Being able to adjust the height and angle is great. Color is vibrant and crystal clear. Awesome for gaming and making sure he can see clear is important, quality is as good, if not better than expected and really no need to adjust brightness as it is perfect as is.

Great monitor great price
Style: FHD 240Hz, Size: 27-inch
Looks very clear and feels very sturdy. Bought two for work and looks amazing and clear. Connects very ez and quickly. Only issue and doesn’t have to do with the monitor, is that the power cable and HDMI included are but short for my liking think it’s like 3-4 ft
