WOW! Thanks all. The speed and amount of responces you get on here still amazes me!
Had a fiddle and atm its running at 1280x1024@85hz and seems much better, but still not quite right. Maybe I just need to adjust as I'm so used to my cheapo 22in TFT.
Is a Dell Ultrascan P991, didnt think to google the model number, sometimes I'm such a nub LOL!
Cheers for the input all
