Solving HDMI droupouts (ATI HD5650 in Acer’s Aspire 3820TG)
Posted in IT,Windows related stuff by fastcloud on January 11, 2012
After installing a new version of ATI/AMDs driver and Catalyst Center for the Radeon Mobile HD5650 (hybride) my external screen (connected via HDMI2DVI) would occassionally turn black for a second or less. At first, I blamed my screen. I connected another screen but the problem remained, I still observed short, sporadic dropouts.
The solution was getting rid of any ATI drivers on the system and reinstalling the following Acer driver: “VGA_AMD_8.752.0.0_W7x86x64_A”. I downloaded it from Acer’s support Web site.
The download is called: “VGA Driver (Radeon HD 5650 & Radeon HD 5470) AMD 8.752.0.0 195.3 MB 01/31/2011 “.
Then, I followed this steps to successfully reinstall the driver and get rid of the dropouts:
- Uninstalled all ATI related software (Catalyst & Co)
- Uninstalled the drivers of your VGA cards in the Device Manager
- Deleted all ATI folders on the disk
- Booted into safe mode and ran AMD Catalyst TwL Cleaner v3.9.2.cmd
- Rebooted and installed VGA_AMD_8.752.0.0_W7x86x64_A
