This is usually a problem with an AMD service called "AMD External Events Service." It polls for the addition of new HDMI devices but also causes problems when resuming from sleep or if the TV is shut down while the HTPC is left on. Unfortunately there really isn't a good solution other than rebooting or unplugging and replugging the HDMI cable. It might be possible to set up a task to disable the service after your system has booted up, but since I gave up on using AMD GPUs with my HTPC a while ago and went with the Intel iGPU, after encountering too many frustrations, I can't test the specifics of that.
Hello TastesLikeChicken (everyone),
Ive recently helped someone with a similar issue. The user kept getting a driver error message stating AMD External Events module stopped working. After a search I found an explanation and a way to disable this service (btw, its a process that is executed when the AMD External Events utility is started during boot-up, known as the ATI Hotkey Poller that comes with the driver according to the post,
the service is responsible for providing hotkey access to various ATI features. It is therefore recommended to disable the service if hotkeys are not used to manage ATI features).That said, the following steps will help you disable the service:
- Click on the Start Button, and type Service in the search form (where is says Search programs and files (or go to your Control Panel -> Administrative Tools -> Service (Local))
- Press enter to launch the Services tool (once launched, you should be in the Extended page)
- Look for AMD External Event Utility and right-click on it
- Select Properties, and in the Startup Type pull down menu select Disable, then click OK.
I hope the above helps you solve the problem youve described, and avoid having to reboot your PC; give it a try and let me know how it goes.
