This would be to select which signal is output on the VGA connector; the composite video input, the S-video input, or the PC input (presumably some models feature that). > My main reason for buying this device was to see my PAL C64 in color. > Unfortunately, using the composite cable, I didn't get color -- just > grayscale (a kind of dithered grayscale, actually -- more below).

It sounds like your V-Box does not support PAL. The "dithered greyscale" is what you get when connecting any PAL composite video signal to an NTSC-only monitor. A similar thing happens when you connect an NTSC signal to a PAL-only monitor. It may or may not be possible to modify your unit to properly decode PAL signals (and not NTSC). > And some colors, notably the PAL grayscale "colors", actually look > dithered, with every other pixel being a different color (for example, > the blinking cursor).

That would be expected. > Overall I think it's kind-of neat, and while I really wish I had color > PAL, the picture really is nice and it's nice to be able to use a 64 > with a VGA monitor -- I expect VGA monitors to be cheap and available long > after 1084s wear out.

In reading specs for several things like this (and PC TV tuner cards), they often state that a wide range of video standards are supported. However, this usually refers to the range of models which are available. Any given unit may only support one standard. So if you need a certain capability, like PAL compatibility and you live in a country which uses NTSC, be careful. It would be best to test the unit before buying if possible. -- Mark - This message was sent through the cbm-hackers mailing list. To unsubscribe: echo unsubscribe | mail email@example.com.
