Can't play games - Display cuts out after res change

I can change the resolution and the refresh rate but when the monitor clicks (haha, I have a crt) the screen turns blue. I have to reboot and then my resolution/refresh rate are what I set them to

Ya, works just like it should in windows. Thanks, I will look into the EFI strings. I'll have to educate myself because I'm not sure what those are yet

Okay, well EFI studio solved my problem with the video ram being wrong but it's still doing the same thing:(

@newbmacDid you delete all the old drivers before doing EFI Studio?

Will the video work with just the efi strings or do I still need other drivers?

@oneshotHey, I had the same problem. Do you have 2 ports where you can plug your monitor cord into on your video card? If you do then try the other port. Good Luck!

I do but the other is a dvi.. The one I use is a vga. When I tried the adapter I got nothing. The monitor said no signal. Are both of yours dvi's? I will try again though, Thank you

@newbmacAll video will work great with just efi strings.

Hmm.. I tried just the efi strings on a fresh install with no drivers. The video was just as slow as it was without drivers. Maybe I'm doing it wrong? I selected my video card and then wrote to the com.apple.boot.plist. everything showed up in the system profiler except there was no quarts extreme support and I had no option to change the resolution. It was stuck on 1024x768. By the way, thanks for your help. I'll keep trying

thanks man, that fixed it. did you happen to notice it slow down just a hair?

Can you change the resolution inside the system ? Seems like your GFX isnt working properly after all.

Why don't you use EFI strings? It's easy to do especially with a tool like EFI Studio or something.

Also, just curious, does it work perfectly in Windoze? If not,you might try re-seating the card too
