Freezing a VGA Signal

[mattevans]

Bit of a random one for you all

 

Does anyone know of a unit capable of taking a standard VGA signal in and giving the ability to freeze the output.

 

This is to enable something to be shown on a projector, whilst the computer is busy doing something else

 

Many Thanks

The Kramer scaler that I have will. I think it is a V772 or 722 or similar. I'll be in work later so can check if you don't get a better answer before then.

Thanks for the prompt reply

On your projector remote control, there tends to be a "freeze" button. This will do exactly what you described.

I've got dozens of different types of projectors here, and I can't recall any of them having this feature. That is not to say none of them have, or that Joe's hasn't, but it is certainly not an ubiquitous feature.

Some Hitatchi's have the feature (known as AV Freeze), together with a large OSD 'pause' symbol in the top right corner - not ideal, though very useful when trying to work out why the image has not yet changed.;)

The Kramer is a VP-720. Others will do it too I'm sure.

I do realise that some projectors have a freeze button, but the ones I am dealing with dont, which is why I asked if there was a way of frezzing it

Most of the Kramer switcher/Scalers do it, ours is the VP-727 but that's somewhat overkill.

but that's somewhat overkill.

That assumes that this is all the unit will ever do. Add to the freeze function; glitchless switching, multiple sources, up-scaling from composite Y-C and component, PinP, etc.

Well, pretty much all of the projectors in our school have them (and there seems to be a few different makes) so I know that the feature definatly exists! However, I don't know how good these are in terms of 'professionality' so I don't know if this is standard on more professional projectors.

I dont think I've ever seen a projector without a freeze, or still function.

What are you planning to use on the laptop? The extended desktop can be very useful if you just need a holding slide. :)

[revbobuk]

One useful tip is to set the laptop so that the projector is using the 'extended desktop' facility, and then make sure that the desktop background is a suitable 'blank' image - we use a deep blue gradient with our church logo - and that's also the 'bail' slide we use between elements in any projection sequence. Makes transitions between projection programs - we mostly use Media Shout, with very infrequent drops into PowerPoint - much easier to do seamlessly.

Sorry, been away from the forum, and now I am back.

The complete list of current Kramer scalers that have graphics in and out, and freeze function, in ascending price order is, VP-719xl, VP-437, VP-720xl, VP-724xl, VP-725DS, VP-725DSA, VP-727, VP-727xl.
