I've recently come to the realization that my computer monitor screen is not properly calibrated. In different web forums where photos are posted, I'm noticing that I can't make out a lot of the pictures people are talking about - they're too dark. I've also noticed this when printing out CD covers - detail in the shadows that I never saw on the screen. Also, every time I show people digital photos, I have to turn up the brightness (in Photoshop) to anywhere between 25 - 50 %! Needless to say, I need to calibrate my monitor. For a test, I downloaded one of those "black level" graphs whrere the squares go from dark to light and you should be able to see every square clearly - I can only see half before they disappear into all blackness.

I have one of those old "turn of the century" big Dell Monitors that came with my original computer back in 2000. It has two "select" buttons (- +) and two "adjust" buttons (- +) with a row of icons (showing which parameter you're adjusting) with lights underneath on the left. I know that the "sun" icon is brightness and the "half moon" icon is contrast, but I don't know what the rest are.

After selecting "brightness," I hit the adjust "+" button a couple of times and I expected to see a bar graph showing my adjustment, but there was nothing, so I left it alone. I don't want to screw up my monitor so I want to make sure that I'm doing this right. It says "recall" under the select and adjust buttons with "arrows" pointing to two buttons. I assume that you press these to go back to your default settings.

So, how do I go about doing this correctly? __________________

Hi,

The lock that pops up is called OSD Lock, with this there are no adjustment can be made by a user and only menu button will work. For you to disable it, just press the menu button for about 15 - 20 secs.

I hope this will be able to help you resolve the problem.

If the light is green, I suspect that the backlight has gone out on you. This could also be caused by you having the brightness turned all the way down.

You need to chek for shorts between Emitter and Collector of the transistors C5707 in the inverter circuits, and also check the fuse PF751 for less than one Ohm resistance. Here are the pictures: http://s807.photobucket.com/albums/yy352/budm/Dell%20E15x%2017x%20series%20PWR%20INVERTER%20BD/

Post back what you find so we can guide you further.

The Up or Down button on your Flat Panel monitor is stuck. Please contact Dell Tech Support to have the monitor replaced if this is still within warranty

Sound like either the button is stuck or the display is in error.

press and wiggle the buttons carefully, and disconnect the power to the display.

Mos likely the menu (or one of the buttons) has malfunctioned and is shorting. You can try to shake or wiggle the button to try to loosen it.

Or there is a malfunction with the circuit board and there's not much you can do. You can send it in for repairs but that often costs a lot of money and the problem could come back. If it didn't cost a lot of money to buy or is older than 4 years, I recommend you buy a new monitor.

Brightness is adjusted by using the 2 buttons on the left side of the front.
