Apple TV via Lindy 2 port VGA&Audio

[BeanDaCat]

At this school we have installed Apple TV and are using a Lindy 2 port VGA & Audio switch. The presentation on the projector for the ATV is perfectly clear, but when switching to the PC output it is clear on the projector screen but the resolution on the PC monitor comes up as either "out of range" or blurry. We have played about with the resolutions and have ended up with some weird combinations to get a picture on the monitor, blurry or not. Currently using ViewSonic 17" monitors. Last room I outfitted had me setting resolution to 1024x768 at 70Hz, just to get a less blurry output. Any suggestions?

We've used some of the Liny VGA/audio switch boxes for Apple TVs without any issues. The computers have 2 graphics outputs, one to the monitor, one to the VGA switch.

 

Are you using some sort of VGA splitter? Is it powered? Are you splitting the output from the Lindy VGA switch or splitting the output from the PC?

What we are doing is one line straight to the Lindy from the PC, a separate line from the Apple TV, via a Kanex box, VGA, to the Lindy, with the Lindy then putting a single line to a separate powered VGA splitter, which goes off to the PC monitor and then off to the projector. To complicate things we have more than one AV solution in the system. Some have a SmartBoard solution, with integrated control panel, but with various versions of the control panel set up implemented. Some with a Promethean set up, with separate audio and visual output. The Promethean's have an issue where the Epson projector can't make up it's mind whether it is going to be an PC projection or an ATV selection (keeps jumping between the two)l. Have added a PSU to one of the Lindy boxes, it stops the jumping between the two devices but prioritises the PC. Does not allow the ATV unit more than 3 seconds of connect time before reverting back to the PC.

 

Must apologize for the grammar and information in this reply,just returned from a Royal Engineers Association Branch Meeting, where beer is a standard form of communication, and I drink Guinness.

General query in relation to this, would a HDMI video capture PCIe card be able to run Apple TV?
