Rated 2 out of 5 by from It’s is a good monitor, but with issues After having this monitor for a few weeks, it was good until today it came with a black little dead pixel… Which is very unfortunate considering that this is a high end monitor and put in my good money and could’ve gone different ones. Don’t get me wrong this is amazing monitor and all, but honestly better options after having this situation and plus acting up with my pc even when I got dp 1.4, come on sony you guys are a goated company but I can not recommend this to anyone from some reviews I’m seeing. I’m just hoping that I’m the future of these monitors you solve these issues!!!

Rated 4 out of 5 by from Made for PS5 and remote work If you have a little extra money to spend and enjoy Sony products you cant go wrong. Works great for PS5 gaming and my remote work set up. Hoping sony improves the "scanning for signal" issue but it doesn't get in the way of my day to day needs. There are cheaper options but this was the way to go for me.

Rated 5 out of 5 by from Great Monitor! [This review was collected as part of a promotion.] "I had the opportunity to try out a 4K gaming monitor with G-Sync, and I have to say I was thoroughly impressed with the performance. The 27-inch display may be a bit smaller than some other options on the market, but the high resolution and fast refresh rate make for a stunning visual experience. One of the standout features of this monitor is the G-Sync technology, which helps to eliminate screen tearing and input lag. This is especially useful when playing fast-paced games or when using a high refresh rate, as it helps to keep the gameplay feeling smooth and responsive. In terms of connectivity, the monitor has a range of inputs including HDMI and DisplayPort, making it easy to connect to a variety of devices. The on-screen display is easy to navigate and allows for a range of adjustments to be made, including color calibration and the ability to turn on and off various features such as the G-Sync technology. Overall, I was extremely happy with the performance of this 4K gaming monitor with G-Sync and would highly recommend it to anyone looking for a high-quality display that delivers an immersive and smooth gaming experience. The smaller size makes it a great fit for any setup."
