    After awake my PC from sleep... Both Monitors show No Signal, but PC L


    After awake my PC from sleep... Both Monitors show No Signal, but PC LEDs are ON, and PC is working, and also CDROM drive can ejected... I use hard shutdown [5-sec press ON button] and restarted OK... what the reason of this? the graphics card?

    Hi lse123

    When did this start? Has Windows recently updated drivers?

    If you disconnect both monitors and then plug one back in does the monitor wake up ?

    Your spec says Win 8.1, are you on 10?

    What are you connecting your monitors to, integrated display ports, expansion card? (Models)

    Have you tried upgrading or rolling back display driver?
