Video to VGA

This might be a dumb question, but, i've seen on ebay and other places this piece of hardware : Geniatech V2VPro Video to VGA Up-Scaling Converter/Switcher at a price of 41usd plus shipping (12usd to portugal) aprox 35 euros, and asking the manufacturer if i could connect a 15,75khz vga signal and would it convert it to the vga 31khz of my LCD, the response was that it woud work. If so why do whe need scandoublers?? Am i missing something?!?

This is the converter:

Hello there, a VGA Up-Scaling Converter / Switcher is in fact a scan doubler, as you have noted it takes a 15kHz signal and converts it to 31kHz (or more as the case maybe)

I will suggest caution though as some cheap units do not de-interlace (cure the flicker) from interlaced screen and you are left with a mess!

I would suggest the following to anyone.

I have one of these and its clearly awesome, I had a wonderfull stable picture from my amiga (in 1280x512x8 super hires laced) scaled nicely on my 42" Plasma in 16:9, also on my 19" AOC monitor in 1280x1024x32

its great

Humm, even cheaper! what do you use to conect your amiga to the video converter?

The one you sugested states it might not suport pal-b or pal-g (portugal standard), does this mean i could not conect it to my tv?.

the unit has 4 possible inputs

SVideo
VGA
RF
Composite

I have tried the RF / Composite and Svideo all are great, Svideo being almost indistinguishable from RGB, I am yet to try the VGA to see if it can handle 15kHz input.

Ops, the price is in British pounds, it's a bit more expensive than the v2pro, and both have the vga in, does the cable comes included or is it easy to buy one (vga in, seems a dim socket).

yes 13 pin dim, not all that uncommon, i think i have a couple i got free with graphics cards LOL.

I am unsure of the v2pro, i had considered this unit a while back but when instead with the link i put up... do you know if the v2pro de-interlaces the image and then scans them up ?

if it does then, well the argument is a mute point as they would both be doing the same thing.

@JLPedro
just reading up the specs of the unit you posted

so yes it does de-interlace the picture... this is a pretty good price for this type of unit... i will certainly consider one of these for my next project...

a good find indeed!

Yes you probably have those cables from gfx cards but they are 13 pin out to composite or svideo, what we need is vga out to 13 pin dim... and i don't think i've ever seen one of them...

you wud be hard pushed to find one, even on the web. sorry mate

Ok, i've brought one

for 50,94usb (34€), when it arrives i will test it and post the results here. Thanks for the help!

But returning to the original question, if it actualy (will have to wait and see) receives the 15,75khz vga signal and converts it to a vga 31khz or more with deinterlacing, why do whe keep seeng scandoublers on ebay seeling for $$$$? There must be some diferences for shure! anyone knows what they be?
