Can I use MacBook Pro as a display for AppleTV? Can I use MacBook Pro as a display for AppleTV? I'm often traveling and I don't have always external monitor for testing tvOS apps on the device.

Thanks, Milos

PS. I can connect AppleTV with MBP using USB cable, open QuickTime player - movie recording and I will have MBP as a display. Problem is that AppleTV stopped working as soon as I unplugged HDMI cable from monitor or device. I tried with the turned off the monitor and it also works, so I need a way to fake it AppleTV that there is a monitor/tv.
Unfortunately you can't put a MacBook into Target Display Mode like an iMac, so short of disassembling your MacBook to wire the internal Display Port the monitor uses to one of the external ones (assuming your Mac has one) there doesn't appear to be a way.
