Bootsiuv and Husar, some people are more sensetive to LCDs according to my eyedoctor, I happen to be one of them. And as I was telling Husar on IRC before it booted me off, the modern LCDs aren't nearly as bad, the older ones were really, really miserable. I've tried fiddling with brightness, contrast, all the settings, even asked my eyedoc for advice, and nothing has really helped. I guess I did exaggerate a bit on how quickly it happens, with a really good high quality modern LCD panel, I can use it for a few hours, but after that I need to stop or I will start to get a progressively worse headache. Apparently more than a few people also are in the same way, so I wanted to caution our own dearest Caius before he drops some serious $$$ on a new monitor.
