Dell Inspiron 518
Version of Windows that is running:
Windows Vista (64-bit) UPGRADED to Windows 7 (64-bit)
Video Card make and model:
ATI Radeon™ HD 3400 Series (no longer have it) UPGRADED to Sapphire ATI Radeon HD 4650
Secondary Monitor: Philips LCD TV 42PFL7704D
Hello, my only annoying problem with my desktop computer is that I cannot detect my secondary monitor via HDMI to HDMI cable. My computer does detect both monitor before Windows boot up, but once Windows boots up my LCD HDTV loses the signal. I tried uninstalling and reinstalling my video card and monitor drivers, nothing! I updated both drivers to the latest update, nothing! My only guess is that this video card HDMI port is faulty. I can sometimes manage manually detecting my secondary monitor via Catalyst Control Center, but that is not useful since my computer detect it as a HDMI to DVI connection -___-. My HDTV should not be issue here because all four HDMI port on my TV works fine with my PS3, Xbox360, and Cable box. I even have many HDMI cables to chose. Please help me or give me a different approach in fixing this issue. My only solutions so far is to either buy a new video card or reinstall Windows, which I DO NOT want to do unless it would fix the problem. Any help would be great, thanks in advance.
