Often even a higher peak luminance can be achieved under certain conditions. For example, when a smaller area/APL of the display is used for showing a bright object, when a bright object is displayed for a short time, etc. There are various panel technologies. Each has its own specific features - viewing angles, color reproduction, response time, brightness/contrast, production cost, etc. The image quality depends directly on the type of the display panel used. 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. Overall, enabling HDR for compatible content might make some video games (mostly X1X and PS4 Pro console games) or movies look a bit better, but most of the time you will just get either oversaturated or washed out colors. Other than that, the LG 27UK650 performs quite well. It has low input lag of ~9ms which ensures no noticeable delay between your actions and the result on the screen. Features

bugNeah, HDR is about supporting a larger luminance range. You can't physically do that, if you're constrained to a limited color space to begin with. Nice things like viewing angles, screen tearing, and even response times aren't really an issue anymore at all in even midrange displays. The storage temperature shows the range from a minimum to a maximum temperature, within which storing of the display is considered to be safe. The operating humidity shows the acceptable level of humidity, in which the display will function flawlessly. It sets a lower and an upper humidity level for safe operation and is measured in percentage.

Approximate height of the display. If the manufacturer does not provide such information, the height is calculated from the diagonal and the aspect ratio. The percentage of the approximate area, taken by the active part of the screen, to the total front area. Just like most 4K IPS monitors at this price range, the LG 27UK650-W is based on an IPS panelwith 10-bit color depth (8-bit + FRC), 99% sRGB color gamut, a 1,000:1 static contrast ratio, and a 350-nit peak brightness. Moving on, theLG 27UK650 display supports AMD FreeSync,which provides a variable refresh rate (VRR) for compatible graphics cards. I think this is a good 4K monitor for console gaming, just don't expect much from the HDR. Having said that, if you can find the UK series for significantly cheaper, I would recommend that over the UL series since its basically a refresh.

Information about the maximum vertical viewing angle, within which the image on the screen is of acceptable quality. The dynamic contrast shows the ratio between the brightest and the darkest color, which the display can reproduce over time, for example, in the course of playing a video.

Oct 23rd 2023 Qualcomm Snapdragon Elite X SoC for Laptop Leaks: 12 Cores, LPDDR5X Memory, and WiFi7 (32) Information of the number of pixels in a unit of length. With the decrease of the display size and the increase of its resolution, the pixel density increases. Approximate diagonal size of the display. If the manufacturer does not provide such information, the diagonal is calculated from the width and height of the screen. For consistency, we've changed the swivel adjustment from N/A to 'No'. The score remains unchanged.
