Godwin, That is brilliant, Thank you very, very much indeed. I would like to explain. I am a dyslexic, I'm sure you all have noticed it. I have tried in vain to explain to people that we need not only good resolutions, but just as importantly good screen refresh rates. I cannot understate that. In the UK where I live our domestic electricty supply comes @ 50Hz,which means our lighting, particularly flourescent pulses @ 50Hz, and for me anything less than a 70Hz screen refresh rate positively hurts me to watch for any length of time.The flicker which is of relatively minor irretation to some people, positively makes my head ache. I know that 70Hz is the minimum I need, so getting the refresh rate up to 75Hz is very important for me. I have now achieved that. It works. I don't care if it does stress the monitor, though I think this may not be the case, I have achieved 1600x1200 @ 75Hz in windblows (I think it's true, not just claimed, dyslexics tend to notice these things rather sharply) In anycase it's a cost I'm prepared to pay. I also want to thank you for the explanation which answered a lot of the questions I had wanted to ask for a long time.I'm going to keep a note of it.
