djmatthill Posted August 25, 2008 Share Posted August 25, 2008 I think I know the answer to this already but im just double checking. Is the any way I can re wire a Vga Computer monitor to show a Composite video signal , Colour or even B&W ?? Quality not that important. I know you can buy converters and scalers ect , But Is there any way bu just re-wiring the din plug. Im not sure there is but , thought Id ask anyway ..

jason5d Posted August 25, 2008 Share Posted August 25, 2008 afraid not, you need a scanny Link to comment Share on other sites More sharing options...
KevinE Posted August 25, 2008 Share Posted August 25, 2008 Jason's right. Scan converter. :) Link to comment Share on other sites More sharing options...
Nick Mawer Posted August 26, 2008 Share Posted August 26, 2008 NO, you DO NOT need a Scan converter - you DO however need a scaler - I would of course recommend one of ours such as the Kramer VP-413 http://www.kramerelectronics.co.uk/indexes...asp?name=VP-413 which has a list price of £249 + VAT. A scan converter converts VGA to composite allowing a computer signal to be shown on a television. In this case djmatthill wanted to play composite on a VGA monitor.

grizzly Posted August 26, 2008 Share Posted August 26, 2008 To be fair, there is a bit of confusion 'out there', with the term 'scan converter' often being used when people mean 'scaler'. Two examples here:http://elm-chan.org/works/sc/report.htmlhttp://www.asm-pc.com/SC.htm Link to comment Share on other sites More sharing options...
Toxopholist Posted August 26, 2008 Share Posted August 26, 2008 That was quite an emphatic no! Please see here for a accurate definition of scan conversion. In this case the OP needs to convert a composite sync signal to a separated Horizontal and Vertical sync as well as change the sync frequency to make it data monitor friendly. Scan converters do convert both ways... For a real life example see the Folsom Image Pro, although this unit also includes scaling capabilities. A scaler as defined here changes the resolution of an image, the top of the range models allowing fully variable scaling, less capable models being limited to specific resolutions. While the model mentioned above will scale the image from composite PAL at 720x576 to a variety of Computer monitor compatible resolutions, it will also acheive an element of Scan conversion from a composite sync to a VGA compatible Horizontal and Vertical sync, odds are it will also need to up-scan from video at 50Hz to Data at 60hz. While Kramer choose to call it a Scaler, it is not wrong to refer to such a device as a scan converter, indeed most of them need to be able to do both. I hope this clears things up a bit Charlie Link to comment Share on other sites More sharing options...
djmatthill Posted August 26, 2008 Author Share Posted August 26, 2008 Oh well thats that then , I di nt think It could be done without other hardware needed. Only asking because I have about 15 old CRT Monitors from a Re fit we ve just done and wondered if they could be used in our hirefleet as monitors for our kararoke systems. But its cheaper to buy an old 14" Tv , as I can buy them for £10 each. Oh well thanks anyway guys . Them monitors will be going on Ebay at No reseve I fear :ph34r: Link to comment Share on other sites More sharing options...
Nick Mawer Posted August 27, 2008 Share Posted August 27, 2008 Sorry if I came across a bit heavy handed, but because there is confusion out there, I think that it is important that people use the right terms. I can tell you from experience that people order scan converters, get scan converters, and then find that they need scalers. We are not the only manufacturers to use this valuable distinction. I believe that TV One, Analog Way, Extron, Communications Specialities and others make the same distinctions In the case of the Barco/Folsom Image Pro - their marketing material refers to it as an "image processor". This image processor happens to include both up and down conversion or both scaling and scan conversion, as did the Sony DSC1024 before it. grizzly - I am not familiar with either of the websites that you refer to. However, I would be prepared to say that they both use the term scan converter in a misleading way. Link to comment Share on other sites More sharing options...

Nick - they were just a couple of random webpages I found, to illustrate my point.I've always used the two terms in the way you describe. Link to comment Share on other sites More sharing options...

I'm actually buying 2 right now (53.99$USD after rebate) to be able to use 2 video feeds (Conductor & Stage) up in the booth on 2 old LCD Monitors. http://www.tigerdirect.ca/applications/Sea...mp;sku=O38-2028 Something like that will let you use Composite/S-vid/etc... inputs into an LCD. I'm using an older KWorld unit (1680? non-ex) at home to be able to watch TV (has a tuner onboard) and play video games on a 22" LCD that I have in my room attached to my computer. No need to spend 250 quid. Go to your local computer shop and ask them if they have these, or if they can get them. Link to comment Share on other sites More sharing options...

I'd say it's a case of you get what you pay for. Link to comment Share on other sites More sharing options...
