Sometime early this year, thinking (wrongly) that I would never want greater resolution and going for low price, I bought a Samtron SC - 43IV standard VGA monitor. I've had very good luck with this monitor. It looks very nice (using a Paradise Basic VGA). Now I'm wondering if its possible to use this monitor with higher resolution cards? What's stopping me? Will the monitor simply not produce higher resolutions? Could I damage the monitor? Will it flicker? It is not (I don't think) a multisync.

Well, the particular model you mention does not ring a bell, but since you tell us that it is a "standard" VGA monitor, then yes, you are limited to using it with non-super VGA cards. You need a multisync monitor to go to 800X600 or 1024X768. What happens is that the video card sends out a signal that tells the monitor to slow its scan rate so that it can display more pixels. Standard VGA monitors wont know how to interpret this and will just try to go ahead and display the picture anyway. It will result in you seeing a lot of garbage on your screen.

It is not a multisync, and it will not work at above 640x480.

Let me give you a few facts (ignore what others have said, at least one of them is 180 degrees off course) and why don't you see if you can extrapolate from them. (the following is simplified for tutorial purposes. EGA/CGA emulation modes and 8514 interlaced type displays are not considered here) Computer displays work by displaying one dot at a time, very fast. They scan from left to right to make a line. Then they move down and paint another line. The number of dots per line is 640 in 640x480 mode and the number of lines is 480. A complete set of lines makes up a frame. A frame is usually displayed 60 times a second. You can't play with this too much in the slow direction or it flickers. Making it faster reduces flicker but there is a point of diminishing returns. Assume a fixed 60 Hz frame refresh. How are you going to put up more dots? What happens to the amount of time you get to display each line? -- Whatever happened to Global Warming? Could we have some Local Warming?
