Seemed like a deal-breaker for some users back then, since the PS5 and Xbox Series X were expected to feature full 48 Gbps HDMI 2.1 support. Meanwhile, the Xbox Series X launched with bandwidth limited to 40 Gbps, and just recently, users discovered that the Sony PS5 HDMI 2.1 support is capped to only 32 Gbps. Turns out the LG CX owners are safe after all. Vincent Theo from HDTVTest demonstrates in his latest Youtube video how to check for the exact bandwidth of the HDMI 2.1 connection on the new PS5 consoles. Initially, users noticed that the PS5 video settings included a problematic description for the 4K HDR mode refresh frequencies, according to which the PS5 would lower the chroma resolution to YUV422 when outputting 120 Hz video signals. Theo went ahead and checked the Freesync hidden menu on his LG CX to verify these claims, and it turns out that the PS5 is using only a maximum bandwidth of 32 Gbps and it is indeed lowering the chroma resolution to 4:2:2 in 120 Hz mode due to the limited bandwidth. The Xbox Series X is clearly superior in this respect, as it manages to keep the chroma resolution to 4:4:4 thanks to the 40 Gbps bandwidth. Is the 4:2:2 chroma subsampling really a deal-breaker? Most movies only support 4:2:2 or even 4:2:0 and the HDR ones that support 4:4:4 run at 24 Hz, hence the skewed color info will solely affect HDR games running at 120 Hz, but there are just a handful of such games for PS5 currently. We cannot say for certain that this is a hardware limitation. It might be a software limitation that can be corrected through a future update, but Sony needs to clarify this as soon as possible."

Hello, I would like to submit a feature request. Settings > All Settings > Sound > Expert Settings > Digitial Output Audio Delay Requesting ability to set a unique value for use in game mode. I use my QN55Q90TAFXZA as a monitor on PC, but I also use it watch Netflix and Prime Video via the TV's builtin apps. (as this is the only way to get a 4k stream) I have a soundbar connected to the TV. The problem is that the 100ms delay is perfect for watching movies (when all the extra screen processing needs the audio delay to keep things in sync) but is NOT perfect when gaming. I would like to be able to configure the audio delay for 0ms for game mode ONLY. Currently, this setting is universal. Please allow us to configure unique audio options for game mode. Thanks.
