Viewport USB to VGA adapter for Windows
This looks like it may be a better alternative to
Tritton's SEE2 USB 2.0 adapter that does the same thing —
provides a VGA/SVGA signal over USB so you can add a second monitor to a desktop or notebook. The Tritton is limited to
800 x 600 resolution at 32 bit color, but the Viewport for the same price ($99) will do 1280 x 768 (and will do 1280 x
1024 at 16 bit color). The Viewport offering is Windows only, but
Tritton also makes one of these for the Mac.

Any thoughts about how many of these can be added to a system? What would prevent you from putting together, say... 10 or 20 of these with a few USB hubs?

USB bandwidth for one...
jazzay @ Dec 19th 2005 1:24AM
why not just use up 2 or more USB ports and have something that can provide good resolution

Any figures on USB bus speeds (actual, not the 480 MBps USB2 speed) vs PCI bus speeds used for monitors?

i think i'll just go with a new graphics card, mabye they should make a firewire version of this?
saq @ Dec 19th 2005 1:24AM
wow so you mean i can spend 100.00 + on this instead of buying a $10.00 2nd graphics card?? where do i sign up?

Hrm... 1024x768x32x60 = 60 megabytes or 3840 megabits per second; I knew it. USB cant transfer THAT kind of data. They have to be compressing it SOMEHOW. It's very alluring to use the USB bus as another monitor plug, though.

I suppose this is only useful for laptops or other devices that don't have slots for additional video cards.

Well, it would be really great for Mac Minis if I'd support Macs :(
I do have a Mac Mini at work, but I'm only using it as a 2. computer, my primary one still being a 1.5ghz P4, because I need a 2. Monitor (Work-Wise) and I can't plug one in. (And Powermacs are a tad too expensive :) )

Don't most present day video cards come with two VGA outs or at least a VGA and DVI out? My GeForce2 that I bought 5 years ago had that functionality.

er... KirbyMeister - "60 megabytes or 3840 megabits per second;", wrong - unless somehow you managed to cram 64 bits into a byte. 60 megabytes = 480 megabits.

kirbymaster, your calculation assumes that the entire display content is sent each frame. clearly this would be the worst approach, since most of the time, there are few, if any, changes frame-to-frame.
so, these calculations are bogus.
