Any known alternatives to SwitchResX for disabling the imac screen?

[W1MRK]

Hello everyone. I have a mid 2010 imac 21.5 (OS 10.8.2) with the annoying yellow screen issue. I am currently using a 32" 720p tv as a monitor (with displayport adapter) and it is working well. The software I found to kill the imac display is called SwitchResX version 4.

Before I upgrade from the trial can anyone tell me if there are other alternatives to disabling the video feed to the imac screen. I am not overly concerned about whether or not the screen is completely off led wise, I just want to make sure the 5670 video card is only sending to one screen (external monitor) and not being overtaxed during gaming.

Thanks in advance.

Have you tried getting the screen replaced? Apple is known to sometimes fix such issues even after the warranty has expired... even if you haven't purchased AppleCare.

I have not looked into that yet. Might be worthwhile. It is sad that the monitor went bad within 2 years of purchase.
