(Sapphire R9 290 Vapor-X) No HDMI Signal

Hello everyone, thanks in advance for your help.

I'm trying to connect my computer to my TV via HDMI and it won't work.

There's image during the BIOS and up until the windows initialization animation finishes, then it just goes "No Signal".

I've tried uninstalling the drivers, and when using Windows default drivers, it works (though with 800x600 resolution). It's only after installing the proper drives that it stops working again.

The two DVI ports are working properly, my only issue is with the HDMI port.

My OS is Windows 7.

Best Regards,

Victor N.
