--- Comment #3 from NW <nw9165-jjnfov5...@yahoo.com> --- Hi, Thanks a lot for the fast reply and for setting this to confirmed and for considering this. Apparently the title was renamed from "Unable to configure HDMI Content Type bit" to "Set the HDMI Content Type bit to "PC mode"". Changing it back to "Unable to configure HDMI Content Type bit" , because: (In reply to Zamundaaa from comment #1) > I don't think we need an option for this, we should just set the correct > content type bit to put the TV into "PC Mode".

Hardcoding it would not be ideal. Because some users might use a KDE Plasma computer as a HTPC for example, i.e. might want the connected TV to be in Movie Mode instead. In PC Mode, most of the TVs built-in image processing is being disabled, which is beneficial for computer content, but is not necessarily beneficial for video content. Also, some users in some cases might not want to specify any HDMI content type, so that the video modes and picture settings on the TV can be controlled manually by the user via the TVs built-in OSD menu, without the graphics driver interfering. For those reasons, the HDMI content type probably should not be specified by default. A user configurable option would be preferrable. It could be added to "System Settings -> Display and Monitor -> Display Configuration", via an additional drop-down, similar to the already existing "RGB Range" drop-down. > Which content type are you setting on Windows, to enable "PC Mode"?

It can only be set to "Enabled" or "Disabled". Therefore it's not clear which specific HDMI content type is being used there. According to https://patchwork.freedesktop.org/series/41876 , the HDMI content type apparently could be one of the following: * No Data (probably means no content type specified) * Graphics * Photo * Cinema * Game On MS Windows, when setting "IT Content = Disabled", it is probably using "HDMI Content Type = No Data". On MS Windows, when setting "IT Content = Enabled", it is probably using "HDMI Content Type = Graphics". But this is an assumption. It's probably not "Game" for the latter. Because many TVs also have a Game Mode, which is not necessarily the same as PC Mode. (In reply to Zamundaaa from comment #1) > Currently we're setting it to "Graphics", > unless a fullscreen application with a different content type is open How is it being determined which HDMI content type should be used for some fullscreen apps? Is the HDMI content type being specified by the fullscreen app? Or is some logic built into KDE Plasma which decides which HDMI content type to use for certain fullscreen apps? By default, KDE Plasma probably should not specify the HDMI content type. A user configurable option would be preferrable. It could be added to "System Settings -> Display and Monitor -> Display Configuration", via an additional drop-down, similar to the already existing "RGB Range" drop-down.
