LE ACCORDING TO LGD, THE CAUSE IS THE OLED PANEL NOT THE OLED TV SET. 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. 根据LGD的说法就是当输出帧率不及120HZ情况下开启VRR，就会造成GAMMA偏移。但是问题来了，现在唯一的VRR游戏设备是XBOX ONE X，用的是HDMI2.0，输出上限就是4K 60HZ。但下一代主机用的是HDMI2.1，那主机在系统层面上输出的就是4K 120HZ，就算游戏是以30帧运行，设备输出依旧是4K 120HZ信号（游戏运行帧率与主机帧率无光，就好比PS4 PRO大部分游戏是4K 30帧，但是输出信号依旧是4K 60HZ。）。 在HDMI2.1的基础下，我并不认为PS5/XSX不会在LG C9/LG CX电视上碰到VRR GAMMA偏移的问题。当然这还是要根据PS5/XSX上市后，才能进步了解。VRR的机制并不是改变主机输出刷新率，XBX依旧是4K 60的输出
