You have a filter problem, check power supply for bad capacitors.

To your problem number 1:

I would check to see what the refresh rate is on your main monitor. Especially after waking the monitor from sleep, Windows tend to forget the refresh rate settings on secondary monitor and set it to the same as your main monitor. If your main monitor is set at 75hz or something, it could cause the secondary monitor to display the "out of range" message. When you reset the "extend my desktop to this monitor" setting, it probably resets the refresh rate to 60hz again.

This can sometime be remedied by checking to see if the monitor drivers are installed correctly. A lot of times the video card driver also gets in the way. I've had a lot of experiences with ATI drivers behaving very sporadically with multi-monitor setups, where they will consistently change to "plug-n-play monitor" and thus reverting any custom setting I have.

As to your problem #2:

I've had a fair bit of experience with this as well. The fact that the line shows the same way regardless of the monitor's own tilting orientation, means the error is probably coming from the video card signal rather than the LCD panel itself. This usually is a foresight of a nVidia card that's about to break.

I've went through many, many nVidia video cards over the years. They all inevitably break over time, probably because nVidia relies strictly on third party vendors... and to stay price competitive the third party vendors cut corners wherever they can. I always get the same horizontal line error over time as you described here.

The only way to know for sure, is to get a replacement video card, borrow one from a friend if you can, and see if the same problem still comes up. It's very possible for this to show up on only one of your two monitors. Try switching the monitor output as well, to see if the line now shows up on the other monitor instead.

Have you unplugged the power cord to the LCD? Let it sit for a minute, then try it. ALWAYS buy a UPS and plug any computer devices into it. Doesn't have to be big, a $50 unit will protect it from dangerous voltage surges.

Yes, but the cost is not worth it. If you get it apart you will no doubt find a couple of bulging capacitors. Dell site has the disassembly instructions.

you may haave a bad disc capacitor. they are little round , mostly tan , soldered onto the board. when the go bad you usually get a line down the screen. youw ill have to replaace them one at a time till the line is gone. you may also have a bad screen.
