This monitor from AOC is excellent for editing, movie viewing, and some gaming. It is the best 4K monitor with a 10-bit panel that has a screen size of 27-inches. The frameless design makes it a good-looking monitor that can be used for multi-screen setups with ease. See how it stacks up against the best computer monitors.

In terms of performance, this 27-inch, high-end frameless monitor from AOC offers a 4K UHD IPS panel that has a refresh rate of 60 hertz, and a 5 millisecond response time. Although it lacks AMD FreeSync or Nvidia G Sync support, it makes up with features such as a high dynamic contrast ratio, and 1 billion color support.

This is a great looking monitor thanks to the ultra-slim bezels on three sides. You can easily set up a multi-monitor workspace using this monitor thanks to the design. The included stand is tilt adjustable for added comfort, and can be swapped for a wall mount as it supports VESA mount. As for connectivity, the AOC monitor comes with a DisplayPort, dual HDMI inputs, and a 3.5mm audio in/out jack. The ViewSonic VX2776-4K-MHD UHD 4K monitor also has a good design.


The AOC 27-inch desktop monitor is decent value for money. It has a great 4K UHD IPS panel that offers 5ms fast response time and 60Hz refresh rate. The panel also comes with Flicker Free and AOC LowBlue Mode Technology to reduce eye strain. With support for 10-bit extended color depth, you can enjoy all your movies with better color and details. However, this will require graphics cards that support 10-bit. The monitor also comes with an HDMI cable, and a DisplayPort cable in the box. The LG 27UK850-W IPS LED 4K monitor is also good value for money.
