Calibrate touch screen on a MacBook / Air


Recommended Posts

Posted

So I have one school who purchased lots of lovely Philips touchscreen TV monitors to go with their windows PC's.

 

Philips LCD monitor BDL6545AT_00 LCD monitor

 

These have been great with windows.

 

Now, they want to be a Apple Regional Traning Centre, this means that they have bought Macbooks and airs to go in the classrooms.

 

I was not consulted on compatibility before they purchased the Macs. I arrived in the school and was given them and requested to put them on the network.

 

They are bound to AD and map all the required drives so all is good, except for one thing...

 

I can get the screens to work with touch input, but I cannot work out how to calibrate the touch to the displayed image.

 

The issue is that the Macs have a different display ratio to the screen. Windows seems to be able to sort this out with whatever drivers are installed.

 

Does anyone know a way, (preferable free), to calibrate the touch interface?

 

Cheers

Would I be correct in assuming you're running mirrored displays so both the Philips and the native screen are enabled? Does the issue present itself when you disable the native screen and run JUST the Philips on it's own at it's native resolution?

 

Another possible would be (convoluted) to run virtualbox with a barebones windows install set to run full screen with the calibration software, do the calibration, then minimise virtualbox and see if it retains the calibration thru to OSX, then close virtualbox entirely and see if it retains, then reboot and see if it retains. If not, you could probably use Automator to run virtualbox to initialise the calibration then hide or quit as required. Do it as a read only image with no net adapter.

I do believe the Philips screens aren't compatible with OSX, i'm actually quite surprised it's working at all. You could try and find what touchscreen technology it uses and see if any other screen manufacture use it and support OSX then try there tools but I couldn't even being to tell you where to start.

 

You could also just boot camp them in to Windows but I don't think that really wouldn't go down in a Apple Regional Traning Centre.

Oooooooooh - I've been after these! I know it's off topic but could you tell me if they're hard glass fronted?

Thanks to @Marci and @ovek.

@synaesthesia

In answer to your your question, I cannot remember but I think so.

 

I just checked on the link I posted and saw this

 

MAC 640 x 480 60 Hz

MAC 832 x 624 60 Hz

MAC 1152 x 870 60 Hz

as supported resolutions.

 

So I will try to work with these for now.

 

I might also try windows on the base machine with OSX in virtualbox on top.

 

Cheers

I'd try the other way round first... OSX host, windows guest. Apple will get shirty if they find you've virtualised OSX on anything but an X-Server iirc!

Apple are clear about what hardware you can use to virtualise OS X that does not contravene their T&Cs.

 

It does not have to the EoL X-Serve hardware nor does it need to be OS X Server software. The only requirement is it must be virtualised on OS X and as any Apple hardware will run OS X then any Apple hardware will do.

Unless those Phillips touchscreen TVs have drivers that can be installed on the Mac or a firmware update to make them compatible, I doubt you are going to get calibration to work. We purchased a Commbox touchscreen last year and calibration was way off with Macs until we contacted them and they sent us the correct drivers/firmware. Everything worked fine then.

I work with the Philips Touch regularly and they will work if calibrated properly, however will only be single touch.
