    Hey all,

    I have a Samsung Syncmaster 175V LCD monitor with a dim picture. It's
    almost like the backlight is bad, but then when you use the on-screen
    display, the menu is perfectly bright.

    The menu appears "locked", and one time I did manage to get it
    unlocked by pressing some button sequence, but have not yet been able
    to repeat the feat.

    After unlocking the display, the monitor seemed to be fine (i.e. full
    brightness across the entire screen). However, every time the monitor
    is turned off, it returns to this dim state.

    I did some Google searches, and did see similar problems, but no real
    solutions (one person did have an identical problem, but htere was no
    solution posted as yet).

    Any ideas? This monitor was very nice in it's day, and considering
    the OSD shows up nice and bright, I tend to shy away from a backlight

    Thanks for any help!

    So you cannot get the monitor's setup unlocked?

    Between last night and today, I found out how to unlock the controls
    (hold + & - at the same time), but they become locked again. I don't
    yet see a pattern other than they get locked if the PC and monitor get
    turned off.

    I will be trying a second video card shortly as well.

    Very odd.

    Yes it is odd. Why not leave the monitor on? It will go into sleep mode if
    you shut the PC off. Maybe then the settings will stay. Very tough to
    trouble shoot stuff when there is no pattern to replicate the problem.
    Kind of like the high speed setting for the fan on my Chevy SUV. Sometimes
    it doesn't blow. You can mess around with the knob all you want but there
    is no pattern. It never stops when on high but sometimes will not switch
    to high from a lower speed. And it will never go on if the switch is
    left on high when it's not working but you can switch it to a lower speed
    and 99% of the time sooner or later it will run when switched to high,
    usually sooner than later.
