LCD Monitors & DVI Vs VGA

[mr. nails]

Oh yea and I hear connecting ur monitor via DVI is faster and creates lest ghosting than VGA because it doen't have to go through digital to analog to digital its just digital strait to digital - so less ghosting. Not sure if ne one stated that yet...

no one has stated that yet, but knew of it in some way or another.

also, could u elaberate on grey to grey? what is the other option? i mean, usually lcds mention 8ms response rate and that's it. it doesn't state 8ms grey to grey or whatever. but i have seen it say grey to grey be4. lol, if any of that makes sense.

Why grey to grey?

LCD pixels can be off (black) on (white) or somewhere in between (grey). This is achieved by varying the voltage supplied to the pixel. In order to switch from black to white you can apply a voltage higher than the maximum needed to achieve white, and the higher the voltage the quicker it switches. This is exactly what they do, it is called overvolting. For rapid white to black the voltages are simply reversed.

To change from grey to grey you can't apply overvolting (but see below) or you will end up going too far and end up with a white (or black if going to darker grey) pixel. Consequently it takes longer to switch from grey to grey.

Since most changes are grey to grey it should be more meaningful to give a grey to grey timing. Unfortunately there is no standard for measuring the levels of grey or at what point the change is determined to have been achieved. This means that it is impossible to give an accurate comparison between manufacturers' figures.

Viewsonic seem to have come up with a method of overvolting even with grey to grey changes, allowing them to quote some very low response times - 2 to 3 ms!!!
