Take the time right now to confirm that your monitor is using the highest refresh rate that it can and a screen resolution that's comfortable for you.
I am perpetually amazed by walking up to a desktop somewhere – say, the catalog at the library for instance – and finding it set to 60hz and 640 x 480. Flickering and pixelated? What sadist set the defaults on this hardware?
I even offer to improve my co-workers' computers if I notice they've got a bad refresh rate. It's astonishing how many people will endure the headache and not realize all they have to do is go to their monitors setting and adjust up as high as their machine will tolerate. What a difference 90hz and up makes!
