I bought a Princeton Graphics Systems Ultrasync 16 monitor last fall. As it is a multisync monitor capable of displaying 1024x768 I assumed that it would handle that resolution in non-interlaced mode as well as interlaced. But in a recent PC BRAND ad it was mentioned as 1024x768i, where the 'i' would mean that it only could handle 1024x768 in interlaced mode. The question: WHICH IS CORRECT ? Thanks for any reply Henrik Vallgren f88hv@efd.lth.se

If the horizontal sync range upper limit is higher than 50khz, you are in good shape to get not only non-interlaceness but also decent refresh rate, the later is FARRRRRR more important then just non-interlaceness. I emphasis again, HIGH REFRESH RATE IS FAR FAR MORE IMPORTANT THEN NON-INTERLACENESS. To get it, you have to have broad horizontal sync range with upper limit well into 60 Khz or higher. Most monitors that I have experience of including some really pricy ones, always overkill in vertical sync range and vedio bandwidth, so you seldom need to worry the later two. GET ONE WITH BOARD HORIZONTAL SYNC RANGE WITH HIGH UPPER LIMIT <- KEY This is the only thing you should care most in shopping a monitor, other than that, it's hard to say, do-pitch? flat screen? price? distortion compansation? color quality? misconvergence? You can make some combos out of these, but please put horizontal sync range as the foremost one. Hope the info helps.
