Scaler with VGA out
Hi looking for component in and VGA out. I already know about Iscan Ultra.
If it has DVI out then presumably this can be changed with an adapter to VGA?
Any others?

Re: Scaler with VGA out
You need a scaler with DVI-i output terminal if you want to use adapter to VGA(Lumagen DVI/HDP have these). Normal DVI-D connectors are digital only and require a digital to analogue convertor.

Re: Scaler with VGA out
Gefen HD Mate Scaler is a cheap option...

Re: Scaler with VGA out
I need VGA out for my Panasonic PWD 6. Would a DVI to VGA change connector do the trick? (Presumably only if the DVI output is DVI-I?) so this would appear to do the trick.
Any reviews?
Thanks

Re: Scaler with VGA out
I have Iscan HD+ that might be going spare (for the right price), PM me if your interested, I'm in Ayrshire.
Has DVI in & out, VGA output + 2 x component inputs.

Re: Scaler with VGA out
Yes the adaptor will do the trick if the scaler has dvi-i output. If you are asking specifically about the gefen mate thing then do a search on this forum and I'm sure you'll get answers as to it's performance....

Re: Scaler with VGA out
Gordon, how diplomatic...
You could get away with an Iscan HD which you'll pick up cheaper than a HD+ as it has no HDCP features which you won't need. Something to note though is that this Iscan won't transcode HD component to VGA (RGBHV) but pass it through as a component signal from the 'VGA' port. I can't recall if the HD+ will do this or not.

Re: Scaler with VGA out
Surely the cheapest, best picture option would be to go for a 2nd hand, original Lumagen Vision. Component in and vga out
Funnily enough I have one going spare so let me know if interested  How's that for diplomacy

Correct, it is only able to pass through component 720p and 1080i through to the VGA output unmodified. Therefore, samhain's display's VGA input would have to be able to accept, and set to, component - as the colourspace of the HD/HD+ VGA output would have to be set to YPbPr (unless he's not gonna watch HD, of course)... |

Doesn't it do this automatically as its a pass-thru?

It detects 720p/1080i via component and therefore passes-through the signal to the iScan's VGA-out port... BUT... if the VGA-out port is set to output RGBHV or RGBS, rather than YPbPr, then, because the HD/HD+ does not transcode YPbPr to RGBHV/RGBS on pass-through, there'll be just a blank/black screen.
However, if the display's VGA-in port is wired to accept YPbPr (as well as the RGBHV standard) - as many modern ones are - then it won't be an issue...
All the iScan is doing is either PROCESSING 480i/480p/576i/576p ...OR... PASSING-THROUGH 720p/1080i to the VGA-out port in YPbPr. But from there, if it's set to output YPbPr to the display, then the passed-through 720p/1080i signal can be displayed, as the in/out colourspace is the same. If it's set to RGBHV or RGBS then it cannot...
The above applies to the digital DVI-out port too.

Re: Scaler with VGA out
Joz,
I think you might be wrong, for the HD+ (not HD), it should be able to process and transcode (if not HDCP) HD signals (720p,1080i) from its DVI input
Confusing, I know!
Thanks
Alex

Yes, the HD+ does process 720p/1080i from the DVI input and transcode any in/out colourspace differential... but not from the component inputs. However, I didn't say that though...
What I said was, that when passing through 720p/1080i from component input, both the VGA and DVI outputs cannot transcode YPbPr to RGBHV/RGBS.
