Information about whether there is a possibility for wall mounting according to the VESA Mounting Interface Standard (MIS). These specs, along with 4K UHDresolution, ensure a stunning image quality, and while the contrast ratio isn’t as high as that of the VA panel alternatives, you do get more accurate and consistent colors.

Response time and motion performance are identical to the UK600 from what I have seen. I would refer to the rtings review of the UK650 for specific values. Information about the brightness of the screen. It is measured in candela per square metre (cd/m²).For a good HDR viewing experience, we recommend a monitor that has at least VESA’s HDR600 certification though these displays are, naturally, also more expensive. Ergonomics Information about the ergonomic functions - height adjustment, swivel angles, tilt angles, etc. VESA mount The maximum number of colors, which the display is able to reproduce, depends on the type of the panel in use and color enhancing technologies like FRC. The UL series sees an upgrade to DisplayPort 1.4, vs the UK series which had 1.2. Other than that, the connectivity options are the same.

Information about the maximum vertical viewing angle, within which the image on the screen is of acceptable quality. Information about whether the stand can be dismounted. Usually, this is required for wall mounting.The ratio between the horizontal and the vertical side of the display. Some of the standard and widely used aspect ratios are 4:3, 5:4, 16:9 and 16:10. This technology removes all screen tearing and stuttering with minimal input lag penalty (~1ms) within the VRR range. The monitor has two VRR modes: Basic (48-60Hz range) and Extended (40-60Hz) range. Nice things like viewing angles, screen tearing, and even response times aren't really an issue anymore at all in even midrange displays. The operating temperature shows the safe temperature range (from minimum to maximum), within which the display will function flawlessly. Outside this range it might operate improperly and/or fail entirely.
