I have a ACER Aspire 5553G, with ATI Mobility Radeon HD 5650.
My computer automatically
installs (besides the card above) a HD 4270 driver
When I disable the 4270 driver and only use the real 5650, the screen goes nuts (Pixel-dancing and shapes everywhere) but the HDMI-out works.
However, if I disable my 5650 the screen is fine but the HDMI-out doesn't work.
I've tried to uninstall all my drivers
, used driver sweeper and started out fresh, but it doesn't work.
Any dear soul out there who have a clue?
