I installed Windows 10 on my laptop and everything works great. Except when I take it to meetings and plug into a projector, nothing shows up on the projector and my screen blinks madly between all black and a grayish screen where I can kind of make out the mouse cursor.
I understand that Windows 10 is alpha/beta... what steps can I take to troubleshoot this problem?
Here are some facts:
- Resolution: 1366x768
- The projector worked fine when the laptop was Windows 8.1
- The graphics card is Intel HD Graphics Family (whatever that means)
- The driver is from May 2014, so reasonably recent and I don't see any updates.
- The Device Manager is all good, except for 1 item marked Other Devices -> Unknown Device (can't figure out what it is - Details tab doesn't really give any info).
