I have set power options to high performance. I have disabled every place in power options I can find that include hybrid or sleep mode. What is strange is only one of the two monitors goes off. The secondary monitor stays on. The first one the user states goes off every night and in the morning she has to reboot the computer several times for the monitor to come back on. Any ideas what could be causing this? I could understand if both monitors were going blank but only one has me puzzled..
