Title: Progressive Scan VGA Box Help
Post by: Concept on December 29, 2005, 04:00:24 PM

I'm looking to buy a VGA adaptor get games in progressive scan on my monitor. Ideally, I'd like something with a switch to avoid having to plug the monitor back into the computer every time. Looking around, I found two possible candidates, #1 and #2.

The second seems to mention progressive compatibility every other word while the second doesn't say a thing about it.

Does this mean that only the second one would work with progressive scan, or is it just implied that any VGA converter with component inputs can?

Also, does anyone have any experience with or recommendations for either one of these?

Thanks for your help!

If you're just talking about the 'Cube (Which I'm assuming you are) the key phrase you're looking for is 480p. The first link you have is more multi-purpose, so if you're looking to hook some other things up, check that one out.

The second one is if you just want progressive scan. In both cases, you'll have to get Nintendo component cables, which last I checked, are hard to come by. You'll most likely have to import them as well.

If you want to skip the middle man, check this option out. I can't vouch for these above devices personally, since I'm fortunate to have an HDTV

Hope this helps some.

I've been thinking about getting one of these so I can play my GC on my computer, but I don't really understand what 480p means.  Is 480p the same as 640x480 resolution on a computer monitor?  If I play on my monitor, will I be able to play at a native resolution?

okay there are 2 different 480's   480i which means 640x480 interlaced and 480p which is basically 640x480 progressive scan.

So then GC games with progressive mode support will play on a computer monitor set to 640x480 without the usual distortion that comes from playing low-res TV content on a monitor?  What about non-progressive games?  Do they still play at 640x480?  How would they look on a monitor?

There are 3 basic outcomes to using a VGA adapter with a current game system.
(the links are made-up screens which illustrate the result)

>> Possibility #1
Conditions:
- GameCube Component Video Cable.
- Progressive scan compatible game.
- VGA adapter with Component Video inputs and supports incoming p.scan signals.
Results:  The game looks the way it should.  Resolution and framerate are intact.

>> Possibility #2
Conditions:
- A game that isn't p.scan-compatible, OR you simply lack a GC Component Video Cable (using S-Video hookup instead, for example).
- VGA adapter *with* a [primitive] deinterlacing method.
Results:  The VGA adapter takes the interlaced signal, poorly deinterlaces it by discarding one field, collapses the scan lines, then upscales it back to its original resolution.  You're left with only half of the original vertical resolution, and 60fps games are cut down to 30fps.

>> Possibility #3
Conditions:
- Game isn't p.scan-compatible, or no component video cable.
- VGA adapter has *no* deinterlacing functions.
Results:  Games show up as mess of interlaced scanlines, or NO PICTURE shows up at all -- i.e. not practical or not worth trying.
