I recently received an LG 27UL650-W, the 2019 successor to the highly regarded 27UK650. Since the UK series is fairly popular among 4K gaming monitors, particularly when it comes to console usage, I thought I would provide a detailed review of the UL650 and how, if at all, it differs from the UK series. For reference, I previously owned the 27UK600 (same panel as the UK650). 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. 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.
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 Nice things like viewing angles, screen tearing, and even response times aren't really an issue anymore at all in even midrange displays. Information about the maximum horizontal viewing angle, within which the image on the screen is of acceptable quality. 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. 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.Do keep in mind that individual units of the same model can and will vary, so the values I provide from testing may not be representative of your specific unit, or of the average performance of the model overall. I performed all measurements using an i1 display pro colorimeter and DisplayCal calibration software. LG has released a new addition to their monitor lineup. The 27UK650-W is an interesting monitor, marrying a 27", 16:9 4K (3840 x 2160) IPS panel with HDR 10 support. The static contrast ratio of 1000:1 means the monitor has a dynamic contrast of 5,000,000:1 (not that that particular spec matters much). The maximum brightness, however, leaves much to be desired on a HDR-enabled monitor: the LG 27UK650-W only manage to deliver 350 cd/m² brightness, which is lower than even the lowest HDR standard AMD considers as being HDR capable (a minimum brightness of 400 cd/m² is required for that). The sRGB 99% Color Gamut coverage is good, however, if not that rare a feature nowadays. The percentage of the approximate area, taken by the active part of the screen, to the total front area. 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.
Both models have decent default gamma. Its close to 2.2 overall in Gamma Mode 2, though its lower (lighter) as the display approaches white. Not something that would be noticeable to an untrained eye though. The energy efficiency class/label provides general idea about the power consumption. There are different energy efficiency classes and each sets its own requirements regarding the power consumption. Some of the existent energy efficiency classes are A+++, A++, A+, A, B, C, D, E, F, G. 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. 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.
What stands out
Size class of the display as declared by the manufacturer. Often this is the rounded value of the actual size of the diagonal in inches.
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. While the LG 27UK650 is a decent 4K monitor for gaming and other use, the ASUS VG289Q simply offers better value for the price. Screen Size Sep 5th 2023 The New Philips 27E2F7901 Monitor Brings High-end Design Features to Content Creators (9) 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.
27UK650-W
What we NEED right now is significantly better color and contrast. There's nearly no performance hit, and excellent color reproduction can look just as good as going from 120 to 240 Hz. I really gotta say that I am fed up with how long it is taking for decent HDR monitors and Quantum-Dot/OLED to enter the market. I don't need a 240Hz monitor lol. Information about the brightness of the screen. It is measured in candela per square metre (cd/m²). 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.
Great Deal
