I have an Acer Aspire 7551-7422 with ATI Mobility Radeon HD4250 graphics. Never had any problems with the laptop. Trying to plug into tv via HDMI, tried two different tvs, both newer flat screens, and used two different HDMI cables. Both cables and tv HDMI inputs work with blu-ray player. The laptop will not auto detect the tv in the control panel display settings, nor the AMD vision engine control.
Any ideas what I may be doing wrong or any suggestions?? I have updated drivers using both the AMD and Acer websites using autodetect and tried rolling back driver to no avail. I have tried restarting laptop with the HDMI cable plugged into both, still nothing on tv(no signal) nor laptop.
I have never used the HDMI before and under the device manager, the graphics card is being detected and working properly.
Thanks
