Hello
I was presenting the other day using a projector at a customer site, and after 5 minutes of the presentation the screen start to flicker and vibrate on the projector. it was very embarrassing. After that I tried presenting with different cables, different projectors and the issue remained the same. I have reinstalled the display driver and nothing helped to fix this issue. I tried working many resolution sets on the screen without success.... Anyone from you had the same issue before, can you direct me to a proper solution before I reinstall my windows... I have Lenovo Helix ThinkPad working on Windows 8.1 64-bit.
