Hello everyone,

I made a post earlier about the display issue i was having so i will just paste that same text in here:
"Lately i just bought a new mac pro. recently i have been doing some video projects in final cut pro 7 (i know its outdated lol) in the video preview it seems that the video has some distortion to it, meaning the the video has a skewed effect to it of some sort. I upgraded from a 2009 iMac which i have never noticed this issue before! I don't think that it would be a hardware issue.. heres my specs:

3.33GHz 6-core
12 gigs of ram
ATI radeon 5770 1gb ram
Monitor: Samsung SyncMaster SA300

I think that it may be the monitor.. as i soon plan on upgrading to a cinema display."

I was thinking of what may be a solution to this.. when i migrated everything over from my iMac to my new mac pro i started getting the same update drivers dialogue on the mac pro that i previously got on the imac. My imac used an nvidia graphics card where as the mac pro uses an ATI graphics card. i have a feeling that the drivers from the nvidia card are now loaded on my mac pro that may be causing this display issue. how do i go about removing the nvidia presences off of my mac pro?

Thanks in advance!

The kexts are located at /System/Library/Extensions/.

Go there and search for "nvidia". Make sure you really only select graphics cards drivers (post a screen shot of the search results here; cmd-shift-4 – let go – hit space bar – click the window).

Then move those kexts out of the extensions folder. Don't delete them right away.

The NVIDIA drivers will do absolutely nothing if there isn't an NVIDIA device in the system.

Sorry to change the topic. Overall how do you like your Mac Pro compared to iMac?

I'm up in the air if should switch to a 3.3 Mac Pro from my current 3.4 27" iMac, Thunderbolt is no big deal since my raid device is esata.

Thanks.

Thanks for your guys replies!

flatfoot, i went there and did not find anything pertaining to the nvidia drivers. i included the picture:

Asgorath, i am just trying to troubleshoot ideas that may be the case even if that is not. however, it would still be nice to delete from popping up on boot-up every tim.

dmax35, I love my new mac pro! i came from 3.06ghz core 2 duo in my imac. so the 6 core xeon is really a huge difference in speed. especially if you do a lot of video work you will truly notice the increase in speed.

dude, stop now

if you can't find your way to S/L/E then you REALLY shouldn't go in there and start deleting things on a whim. You are just going to make a mess.

Besides, it looks like what you are talking about is the CUDA drivers, which are separate from the regular Nvidia drivers.

I am not going to be touching anything. as im way to paranoid to start snooping through files i dont even know exist or what they even do. I have conducted some test and i believe my issue is just the refresh rate of my existing monitor. i just bought a 24inch cinema display. I should not notice this issue anymore after it arrives.

if it is not the refresh rate, do you think that the CUDA drivers may be interfering with anything on my graphics card to account for my issue?

Thanks for your word of caution MacVidCards
