LGE’s 48” OLED Attracting Game Monitor Buyers
Earlier this year, LG launched the first 48-inch OLED TV. The TVs have reportedly been in high demand since launch and sales were boosted by the general stay-at-home entertainment boom from the global coronavirus pandemic. LG reports unexpected demand from gamers. 48-inch OLEDs are not cheap but smaller LCD gaming monitors with similar features, and subpar picture quality, can often cost the same or more. 40+-inch LCD TVs typically lack advanced features to keep costs down. LG's 48-inch CX OLED TV on the other hand offers HDMI 2.1, HDMI VRR, AMD FreeSync, and Nvidia G-Sync Compatible. Sony also launched a 48-inch OLED TV, but it lacks many of the gaming features found in LG's model. Additional TV makers are expected to launch 48-inch OLED models later this year.
Forbes’ reported LGE’s 2019 and 2020 OLED TVs variable refresh rate (VRR) implementation sometimes causes the image to undergo a brightness/gamma shift that makes dark areas in games look greyer and more washed out than they do with VRR turned off. By toggling the AMD FreeSync feature in the LG OLED TVs menus on and off with the Gears 5 HDR calibration screen playing with the VRR feature on, the black floor is raised and, as a result, there’s less visible shading detail in the dark areas of the left side of the Gears 5 calibration image, which is noticeable when the TV’s instant game response feature is turned off and switched to a picture preset other than the Game. There are also reports of noticeable instability/flickering in some dark gaming image areas when using VRR on LGs 2019 OLEDs.
Gamma for OLED is optimized and fixed for 120Hz by establishing a fixed charging time for OLED sub-pixels. VRR is used when the frame rate is less than 120 Hz. When the OLED TV uses framerates less than 120Hz, the gamma curve is inconsistent with the frame rate. For example, a 40Hz frame rate is longer than 120Hz frame rate. Therefore, the lower frame rates results in sub pixels that are overcharged, causing flickering of dark gray images, which is noticeable for dark images rather than bright ones, because human eyes are more sensitive to low gray colors. LGD will likely solve this problem establishing multiple gamma curves optimized for lower frame rates.
