HDMI RGB Colors Limited on Intel i7-10610U UHD Graphics

[rc1305b]

The color range is limited on my HDMI connected monitor, and there is NO option to address this in recent Intel Graphics Command Center update. This is so frustrating...

The option to switch my HDMI-connected monitor to using full color range actually hasn't existed for a while, but my work around was to switch to using YPbBr color instead of RGB, which seemed to restore the full color range. However, after a recent update, this YPbBr option is no longer available. So now my right-side monitor is grayish due to the limited HDMI color range, while my left side monitor has full colors, due to it being connected over a DisplayPort connection (albeit, a DisplayPort->HDMI adapter).

Full setup: Dell Latitude 5510 laptop, using a Dell D6000 Docking station, connected VIA USB-C, with two identical monitors, connected 1 with DisplayPort->HDMI adapter, and another just straight HDMI. The straight HDMI connected display does not have full color range, nor has the option to configure this in Intel Graphics Command Center.

PLEASE just add the option to output the full range of RGB color over HDMI connected screens. Why on earth anyone would want to limit the full color range is beyond me...
