I have a Huawei laptop with Ryzen 5 and Radeon Vega 8 with HDMI but no VGA. When I try to connnect it with the old BENQ projector, using the adapter from HDMI to VGA, it says: "Analog RGB out of range". I tried to change the resolution even to the lowest possible mode but it is not changing anything. Whatever screen resolution I set up, the "analog rgb out of range" is still there. The problem disappears when I connect my laptop directly do the projectors that have HDMI. unfortunately, there are mostly old benq projectors with VGA at my workplace.
I will be grateful for any help.
