    Anyone know if monitors (4 years old Gateway EV910b in this case) have lil knobs inside at the back that can adjust brightness and contrast like tellies do? I'd rather not open the thing if there's nothing to adjust inside in case the cover won't go back together.

    It is what it's.

    Why do you need this kind of adjustment? I'm assuming the default adjustments are way too dark/bright. A lot of video card drivers provide you with this facility in software.

    If the thing is very dark (and it wasn't this dark originally, and you have been gradually turning up the brightness, etc.) there's a strong possibility the tube's getting choked.

    (When I say choked, I mean with soot as the innards toast gently as it runs, especially if it's been running 24/7).

    If I've described your problem well, I'm afraid you're looking at one of the symptoms of old age in CRTs, and it's irreversible (as the CRT itself is sealed). You can try and ramp up the brightness/contrast, but it's a short-term measure at best; you may be looking at a replacement monitor within the year.

    Also, CRTs contain devices (such as bloody large capacitors) that can deliver a lethal (in the fire you across the room category) electric shock regardless of whether the thing's on/plugged in or not. If it is plugged in, well, you're really playing with fire. If you plan taking the back off, please, PLEASE, be very careful. Pick up a set of plastic trimmers in Maplin or somewhere, and NEVER use a metal screwdriver. They may say they're insulated, but plastic/rubber insulation won't save you against these things...

    Yeah, I've ramped the brightness and gamma settings on both the monitor and graphics card software to pretty much highest. The OSD now shows just a dark square so I know it's not the graphics card. So far it's worked fine but I guess one of these days it'll be too dark :dunno:

    Ah well, I needed a good excuse to get me a swishy new TFT so I guess this is the chance I've been waiting on! :)

    It is what it's.
