Yeh, I have that problem at school, the monitors are CRTs all at 60hz, they drive me mad . But the company I work for in London has only TFT's, so no problems there.Sirrel Squirrel said:CRTs give me a headache because I notice the flickering, pretty sure its against health and safety that I have to work 12 hours a day and stare at a screen for at least 10 of those hours they should give me a TFT!
