EYESTRAIN? TRY THIS... A number of readers replied to my Jan. 12 column on display technology, wondering why they developed headaches after a few minutes of using a new computer or monitor. The likeliest cause is screen flicker, and the cure involves increasing the ''vertical refresh rate,'' the speed at which your display adapter redraws your screen. Flicker is most often a problem at refresh rates below 75 hertz. Some Windows 95 video adapters let you set the refresh rate directly from the ''Settings'' page of the display control panel. Others try to pick the best speed for your monitor, but you can trick them by changing the monitor type. Either way, it may take some experimentation to get the settings right.
