The card worked fine until after a Windows Update last year.I don't know which one it was.
When I went to the support page I only found ATI Radeon HD 4850 X2 drivers. I installed them and I when I attempt to stream to my TV by HDMI the image is great, but there is no sound.
Windows Trouble Shooter didn't help. When I test the connection I receive an error message.I have attached a screen shot.
I have Windows 10 Pro 64 bit on a desktop PC.
use the AMD Legacy Driver from driver page!
I tried that driver and the HDMI port didn't work. In early 2018 my drivers
worked perfect.
I might try System Restore or a back up.
well, your card is pretty old and MS did change some stuff in win10
try linux to find out if hdmi is damaged or if its a driver problem
Actually the legacy driver doesn't support Windows 10. The driver you need is the one included in Windows. AMD no longer supports that card, but the driver that comes with Windows works fine. If not talk to MS about the driver or buy a new card.
Thanks for the response.
