I have a PTV3000 I'm using w/ a Lenovo x230 and a Samsung 55" 1080p HDTV. The TV has worked at 1080p for two years. I decided to upgrade my Intel graphics driver and the WiDi software, and all the sudden I am no longer able to get the TV to display in 1080p. 1280 x 768 is the maximum resolution I can get for the TV.
I have tried reinstalling and uninstalling both old and new versions of the Intel graphics driver and the WiDi software. I have also tried resetting the PTV3000 device. I have also tried playing with the graphics properties settings and toggling between Clone and Extended Display. None of these things work.
I have read many previous threads about this issue, and it seems that I've already tried all of the things that have been suggested. Please advise what else I should try. Below if my graphics report. Thank you.
