First off please don't shout ( using all capitals is considered as shouting on a forum ) it will not get you an answer any quicker.

Secondly as you have not said were in the world you are how can anyone tell you what's available were you are.

And lastly is Google broken were you are ?
You are just as capable of doing a web search as the members of this forum are so why should we spend our time doing your search for you ?

It would also help if we knew a bit about the application. Does it need any specific touch data or does it just need a mouse emulation?

Do you need multi-touch or specific resolution?

I assume this is for your vending machine but could be wrong. If it is for that project, you need to get the PM to give the consultants a swift kick and get them to deliver to your specifications.

Why specifically 24 inches?
A 7 inch screen should be sufficient, surely?

I found a few (expensive) hits when googling for "24 inch usb touchscreen" and several hundred (affordable) options for 7" screens.

Can you compromise, or must it be 24"?
I also assume the program expects a high resolution?

the software requires 24inches i have been googling all day they are pretty expensive so it wont be feasable for us to install on 300 vending machines for testing purpose we are using a dell 24inch touch screen monitor on a 90 degree potrait setting it cpst us about 1050 sar

How does your software know the size of the monitor? Now it is usually pretty easy (these days) to detect the monitor geometry (vertical and horizontal pixel counts), but size?

Since you're in Saudi Arabia, one might presume that any text will be in Arabic and I could see needing a specific (reasonably high) resolution for that reason, but that doesn't necessarily equate to a particular panel size.

So what does the software *actually* specify?

I guess the 24inch size is for the cut out in the machine - who knows what happens with the bezel and how it mounts...

Too many questions - not enough info and a set of contractors not delivering - could be a train wreck in the making :shock:

xrandr will report back the monitor geometry, relative position and horizontal and vertical size in mm. From that it would be easy to work out the diagonal size of the screen and even convert it into archaic inches.

You should add the resolution requirement...
