Andy_Moore Posted October 27, 2021 Share Posted October 27, 2021 Hi' All Have been running CCleaner on my SonyLaptop for years. I ran a driver updat on CCLeaner, which found drivers needed to be updated, so ran the program. After a reboot, I found that the external Display on the HDMI port not working. Shock, thought to check on WIn 10 display settings. It reports that no external device connected ? Yes, I tried the reverse driver update option in CCleaner. It failed to function at all. How to I get the HDMI port working again? AndyM. Link to comment Share on other sites More sharing options...
Moderators Nergal Posted October 27, 2021 Moderators Share Posted October 27, 2021 Moved to ccleaner driver updater board ADVICE FOR USING CCleaner'S REGISTRY INTEGRITY SECTION DON'T JUST CLEAN EVERYTHING THAT'S CHECKED OFF. Do your Registry Cleaning in small bits (at the very least Check-mark by Check-mark) ALWAYS BACKUP THE ENTRY, YOU NEVER KNOW WHAT YOU'LL BREAK IF YOU DON'T.
