Screen resolution issue

    I have been trying to solve this issue for over a year.
    Here's the issue, present in both Vista x64 and Win 7 x64.
    Monitor: LG Flatron W2241S (1680 x 1050 native resolution)
    Graphic card: Powercolor ATI 4850
    Catalyst drivers: latest (issue does not depend on version and/or OS).
    Issue: Screen resolution changes to a lower value, icons and text and
    everything gets bigger.
    This happens after waking up the monitor from sleep, either when it comes
    from PC standby state or after having being turned off after 3 minutes (my
    power policy) of inactivity.
    The issue does not occur in any other instance, there is no other
    combination that makes it happen.
    Just when the monitor comes from off to on state and is not reproducable.
    Sometimes it behaves properly (resolution doesn't change) or misbehaves
    (resolution changes).
    Workarounds so far:
    1.- Right Click on desktop, Screen Resolution, Detect, Accept.
    2.- Open device manager. The Monitor entry is not there!. Scan for hardware
    changes. Monitor is back. Resolution is back.
    The issue is present on fresh installs, right after having installed the OS,
    either Vista or Win 7.
    Any ideas?

  2. What are you BIOS Sleep settings? Original mine was set to S1 and I had
    problems. I then changed it to S1 & S3 and don't seem to be having
    problems right now although I think State S3 may be the most desired.

    * S1: All processor caches are flushed, and the CPU(s) stop executing
    instructions. Power to the CPU(s) and RAM is maintained; devices that do
    not indicate they must remain on may be powered down.
    * S2: The CPU is powered off.
    * S3: Commonly referred to as Standby, Sleep, or Suspend to RAM. RAM is
    still powered.
    * S4: Hibernation. All content of main memory is saved to non-volatile
    memory such as a hard drive, and is powered down.

    I think S1 causes problems based on its description.

    What is your DPI set to? 96 - normal or 120 in Vista or 125 in Win7.

    Bobby,
    Using S3, always have, always will.
    Issue was also present with a prior motherboard, Gigabyte GA-MA790FX-DS5.
    Current mobo is Gigabyte GA-MA770-UD3.

    Hugh,
    Set to 125 win Win 7.
    96 is quite small for my aging eyes!
    :)

    Yes, I use 125 in win 7 & 120 in Vista.(for my aging eyes too!)
    I have found a few abnormalities, when you increase dpi from 96 to 125 or 120 .
    Try switching back to DPI of 96 & see if your problems still occur.
    See my email I sent you.

    Hugh,
    Will try that tonight.
    In the meantime I am thinking of a workaround for redetecting the monitor.
    I found this Microsoft utility:
    http://support.microsoft.com/kb/311272
    and intend to place a shortcut in my desktop to a batch file containing
    "devcon rescan".
    That path is shorter than going to device manager and doing a search for new
    devices.
