ATI Hotkey Poller (ati2evxx.exe) - Also called the ATI External Event Utility, this service is primarily needed if you use the ATI Hotkey settings available in the ATI Catalyst Control Center. However, before disabling this service note the following: If you use a third party overclocking utility, you must disable this service otherwise the utility may not work; if you have an XT, X1000 or newer graphics card, disabling this service can also disable the OverDrive section in the Control Center, and can also prevent correct clock speeds being applied in 3D mode; if you run a laptop with an ATI graphics card, you may need to keep this service enabled to allow your LCD screen to switch off properly when the laptop is closed; if you use Fast User Switching then disabling this service may also cause problems with that. If none of the conditions above apply to you, I recommend that you disable this service.
First question: Any idea what atibrtmon.exe actually is? I can't find much on it with any degree of certainty.
My second question would be: Does my graphics card fall into that newer category that's going to inhibit the performance of my card? I have a Studio XPS laptop with an ATI Mobility Radeon HD 3670 graphics card.
The last question: Am I able to disable the process and see if it changes how my laptop screen switches off without any detrimental effects (like my screen messing going blank and me not being able to turn it on)?
I know I'm asking a lot but I'm just curious as it seems to be eating up more resources than it should and I don't recall atibrtmon being there until just recently. I really appreciate any help you guys can spare.
