The ones I have are actually combo devices with an analog tuner and analog VGA/NTSC/Svideo/component inputs. They appear to resample even the VGA input, rather than just being a passthrough in VGA mode, which is very strange. The sampling can be selected to be up to WXGA resolution at VS=75Hz. But they were only $40 :)
If you've found one that produces a stable display from Apple II composite video, with good quality, I'd like a pointer. ;-) All the inexpensive ones that I've seen, or others have reported on, have had sampling artifacts that made them quite unusable for text (with "squirmy" verticals, in particular). These issues would not be a problem with an analog signal or some different dot clocks, but with an Apple II, they're murder. -michael ******** Note new website URL ******** NadaNet and AppleCrate II for Apple II parallel computing!
