Hi Joe,
Unfortunately that is not possible, because I don't have a restore point. I can try uninstalling everything, but I need the old drivers again - can you supply a link for the whole package? When I go to driver download it tells me to run the detecor - I tried to run the driver detect software, but it doesn't run properly on my computer, it starts, but never completes (no error message and the latest version of Java is installed). I have followed all the instructions on that page.
Thanks for your support!
Andreas
P.S.: I succeeded and was able to roll back the driver on the video and it is displaying again on the TV!!! I also have the old controls back and I can now say with certainty, that it was the intel video card driver update, which caused my problem. I suppose you need to issue a new driver, which actually works for everyone - maybe have comprehensive testing done prior to issuing it.
