I am using the club3d display port > hdmi 2.0 adaptor with my R9 290 so that I can display 3840×2160 @60hz. I am connecting to a Toshiba 43u6763db.
No issues with achieving the resolution. However, the blacks are crushed meaning that gaming is not really an option (colours look super saturated, text is harder to read and if you go in a even slightly dark area of a game, you can’t see a thing.
With the adaptor I am unable to change the pixel format because the option to do so is not available in the Radeon graphics control software when output is through display port.
I don’t know why the TV does not display colours correctly with rgb full as the TV should have full range hdmi capability as far as I am aware. I have the HDMI set to Enhanced and can’t see any other options that address the issue in the TV GUI.
I don’t know if there is a fix for this, whether it’s getting newer adaptor firmware/ setting a custom resolution (Please tell me how if this is the case) or whether i have just bought a bad tv.
Many thanks in advance! Any advice would be greatly appreciated.
