Probelm with Acer LCD Monitor

Options
Acer AL1913 LCD Monitor bought six months ago from Comet.

Has been great until recently. Now, if I leave the PC for a while and the monitor goes into hibernation I sometimes cannot wake it up again. The green light displays but the screen is absolutely dead. I have to force the PC to shut down by switching off at the tower, (does this do any harm - I hate doing it?). I borrowed a neighbour's spare monitor and then after a day or so tried mine again and it worked fine for a few days but the same thing has just happened again...monitor...into hibernation and 'dies'. I haven't been making any changes or doing anything differently recently so am at a loss as to why this has suddenly started to happen. Is it me missing something really simple or is the monitor faulty? From what I can make out there seems to be a standard 3 yr guarantee in place.

Any thoughts or ideas please?

    It could lead to start-up problems because the OS hasn't handled the shutdown.

    Sounds more like the graphics card is being told to switch off the display to conserve power.

    While you may not have updated anything, windows probably has.

    When it goes into 'hibernate' moving the house or hitting the keyboard should wake it up and restore the display.

    Which OS?
    Which graphics card?

    Did the monitor you borrow go into hibernation?

    Check these settings,

    Control Panel - Power Options - Hibernation Tab - Is this enabled?

    Also, still in Power Options - Power Schemes - System Standby - Whats this set as?

    ATi (people who make graphics cards) have had a MAJOR headache with monitors going into sleep and not coming back until a hard reboot like you do.

    When the monitor goes off does it disaply a 'check signal'?

    Its worth checking, other than that it could be a trip back to comet. :(
  • Hi

    O/S - Windows XP Home
    Graphics Card - nVidia GeForce 4 MX 440 64MB DDR

    Yes, borrowed monitor behaves perfectly i.e. sleeps and wakes up when told to and the new one only refuses to wake up sometimes.

    Hibernation Tab is 'Enabled'
    System Standby set as 'Never'

    Sorry not noticed about 'check signal' display as not usually watching screen at the time.

    If I try the new monitor and it 'dies' again would it be best to force a shut down or to swop over monitors? (Don't like the idea of messing about with cables while the PC is switched on either!) Which is the lesser of the two evils please?

    Thanks for trying to help

    I would disable the hibernation. Hibernation and the Graphics card you are using (or the drivers you are using) wont allow for the system to awake the graphics signal.

    But then again you said it worked ok on another monitor.

    Try it though.....
