    hz question

    if your lcd supports 60hz as native but shows distortion and u force it to 70hz and it works fine (no distortion),

    can this damage your lcd forcing it to 70hz?

    Re: hz question

    I think the notion of damaging monitors is rather outdated, all modern monitors have built in control computers that make sure everything is OK (as well as displaying the menus etc).

    For LCDs I don't see what there is to damage anyway.

    Re distortion - are you refering to distortion in games or distortion on your desktop. As far as I can make out a TFT won't actually run at over 60Hz at its native resolution (it just drops frames) so you cant damage it as such unless you force way too high at which point you just get a blank screen as it turns itself off.

    distortion on the desktop was using eizo lcd test, 60hz always shows wavy lines, but 70-72hz <forced> shows perfect, so i am using 72hz and it seems to be supporting it.. even tho the native is 60hz

    Re: hz question

    It can be confusing: my monitor's booklet has:

    'the monitor supports the optimal display performance with 1280x1024 at 75Hz' at the front;
    then, in the specs. it says 2 thing:

    Max Resolution 1280x1024@75Hz
    AND
    Optimal Resolution 1280x1024@60Hz

    then(!), in Factory Preset Timings:

    VESA Modes (leaving aside non-native resolutions) 60Hz and 75Hz and
    SXGA Mode 70Hz.

    Now, in the Settings from the desktop, ticking the Hide modes box leaves only 60Hz.

    So, looks as if 60Hz is 'safe' and 75Hz should work but...!

    Re: hz question

    bought a new dvi-to-vga connector recently to see if it would fix the problem it did not, still got lines on grey screen with 60hz and noticed vsync on video playback is bad at 70hz+ i think my monitor is bust oh well

    Re: hz question

    Never really understood the scan frequency on LCD monitors myself either.

    A few people say "oh lcd's work differently than crts - hz doesn't matter".

    Yet for me it clearly does, I can definitely see increased blurring in games on my Samsung 19" SyncMaster 913N at 60hz compared to 75hz, at native 1280x1024 res.

    I'm fairly sure the monitor manual says it's optimal is 1280x1024 at 60hz too.
