hi, this may be a dumb question but I have a geforce 4200 and I was curious if leaving the nview mode set to clone as opposed to just a default single output would be hurting the video card's performance. I'm using the clone mode with video overlay so that playing videos outs to tv but I'd rather not have to change the nview settings every single time tho somewhere I think I once read that performance drops with dual output. Any thoughts? Thanks.
