I posted a thread earlier on my projector and a line streaking problem. After some help from a user, and testing on a PC, I have determined that I really *really* need an external scaler.


But heres the thing. The projector is only 640X480 resolution, so an XGA quality scaler is a waste of time. What I am after, holwever, is a good quality VGA scaler - *cheaply* which performs nicely - cheaply as in I paid $800 Aud ($400 USD) for the projector, so I don't want to have to spend more than half of that again...


So - any suggestions for scalers that will accept either S-Video or component video for under $200 USD that do a very nice job?


I have some examples of what I have found so far - anyone care to comment on these?


Gamars V Box - Svideo and 640X480
http://www3.goldenshop.com.hk/AI-trad/pc/m_vgabox.htm


My preference-local supplier (I am in Australia), auto PAL NTSC switching etc - has Svideo (for DVD) and composite (for VCR/Telly) inputs, correct fixed resolution.



Copper Box - Key Digital Systems
http://www.copperbox.com/lite/popinf...neek=208916146


Okay (ish) no mention of Pal/NTSC, has component only (no good when I want to use with vcr or as TV.


**************** EDIT ***************************

This is not as it is being sold - copperbox describes this as "Key Digital automatic Y-Pr-Pb to RGBHV Transcoder." This implies that it converts composite to VGA - not so - from Key digital - http://www.keydigital.com/detail.asp...ct_id=KD-VTCA1 - "VGA (RGBHV) Input to Component (YPrPb)"


Oops... copper box made a typo?


The real converter from Key Digital is - http://www.keydigital.com/detail.asp...ct_id=KD-CTCA2 - "One Component to Two VGA Video Adapter"


Correct Price is $329.00 USD OUCH!! not $179 :(


I have emailed copperbox to confirm this.

Has anyone here tried the gamars Vbox, or do I have to buy one and try it out :)


Cheers

Note, those keydigital converters are not supposed to be scalers. All they do is transcode.


You better go with something like iScan PRO that has all 3 inputs - component, SVideo and composite (and PAL/NTSC support). It is a deinterlacer - so it outputs 480p, exactly what you need.


It can be had for around $500.


The older units (e.g., iScan+ and iScan V1) are also not bad, but no component inputs or PAL support. Street price is lower than iScan PRO.

Since you only need 480x640 output (or 480p in video terms) then your starting point should be to look for an iScan Plus on eBay. A used one of the original version can found for less than $300 and a new version 2 for around $450. The iScan Pro version adds video controls for color, hue, contrast, brightness and currently sells for about $650 new-discounted (again check eBay listings).

Thanks guys - but I was really wondering how good those *cheap* scalers for PC use were - has anyone played with them yet?


A transcoder (rather than a scaler) - I take it that this doesn't scale the video to the correct resolution, and so will pass through the internal video scaler in the projector... darn...


The thing is, I am trying to do this on a budget - I have paid $400 for the projector (LP550) and the video scaling problem annoys me. So, I wanted to bypass the internal scaler with something that would perform this function reasonably well, cheaply.


I will look into the Iscan Plus - hopefully I can get one for a decent price.


*************************************************


BTW - I contacted copperbox and they confirmed that the price is $179 - I was wrong :(

But as people said, it is simply a transcoder...
