DisplayLink gamma control not working

[Mallwill]

Good morning,

I have 3x DisplayLink devices that I am having trouble with.

When I connect these devices via HDMI to my display - a 800 x 480 display - the colour palette is very washed out and incorrect. I am unable to correct with gamma / brightness control when connected.

When I connect via native HDMI on my PC, the issue is resolved and I do not see colour rendition problems and can adjust gamma successfully.

Please can you help with support.

Thanks
