6930 black screen


Try connecting it to an external monitor if possible.

You can use the VGA connector on your laptop to connect it to the Monitor.

restart the laptop and see if it comes up on the external monitor.

If it does show on the external monitor, It's probably the laptop screen going bad. and they ain't cheap. here's a link to a screen on Amazon, just to give you an idea...
Amazon com HP EliteBook 6930p Laptop Screen 14 1 LCD CCFL WXGA 1280x800...

If it still doesn't show, Hold down the function key and press the CRT/LCD button (Usually F8) to see if you can cycle between the external and the laptop monitor..

Hope this helps

Hp 2010i monitor shaky, can't find degauss option


I don't think degaussing your monitor is going to help with this issue. Degaussing mainly addresses color correction around the monitor edges due to a magnetic field and applies to CRT monitors not LCD monitors which yours is. If by your term "shaky" you mean the image is unstable, then the problem is either in the main board which controls the X Y sync or with the power supply board. If you are knowledgeable with electronics you could probably repair this at home for $40 or less. If not then I would shop for another monitor to replace yours. Don't throw your old monitor away, instead post it for sale on craigslist. There are a lot of do it yourself type people who will buy this either for parts or to repair and resell. I don't know what it will bring as far as cash, might be $40 might be $5 but anything is better than zero.

Elitebook 8470p not displaying to remote monitor with KVM


Is the laptop actually detecting an output when the KVM is plugged in? Try forcing output with Windows + P (Vista/7) or a function key (not sure what it is for the 8470p).

I need to plug an HP f2105 monitor into an HP elitebook laptop


Elitebook has a vga port with is 15 pins. If the monitor only has DVI you can get a VGA-to-DVI-A cable. They are cheap and available on monoprice.com Make sure the monitor supports DVI-A

Make sure to check the DVI port on the monitor for the wide horizontal pin with two small pins on top and two underneath. See pic below.

Monitor does not come on right away, it makes a clicking noise then say no signal analog. after i trun off and on several times it comes on but the screen is wavy for a while


when you say the screen comes on wavy for awhile, im supposing you have a CRT monitor, not the flat panel type. That seems to be the degauss feature when you turn on the monitor which is normal. The no video issue may be a bad video cable or connection the the PC.

Monitor distortion


Hey edwardaaron,

If you are encountering any kind of visible distortion on your computer monitor, there are a couple of things that I would suggest.

First, if you have a cathode ray tube (CRT) monitor, you may want to try manually degaussing the monitor. Whenever a CRT monitor is in use, it slowly builds up a magnetic charge that can interfere with its operation. Degaussing then, is the process by which CRT devices rid themselves of this excess magnetic charge. This is normally done whenever a monitor is first turned on, but many monitors will also have either a button on the front control panel you can press or an option in the main menu to perform a manual degauss.

In many cases, the degauss option will be marked with a horseshoe or magnet-shaped picture. Once you've selected this function, you may notice a metallic-sounding "twang" noise, followed by one or two "clicking" noises as the image on the screen is reset. Keep in mind that images on the screen may appear to vibrate and color may distort for a few seconds after you do so, but this is a normal part of the degaussing process. The screen should return to normal after a few seconds.

Second, interference can also be caused by placing your computer speakers too close to the monitor. Many speakers will produce a magnetic field of their own, which only adds to the magnetic field generated by your monitor. In this case, repositioning your computer speakers should help minimize the problem.

If degaussing fails (or you don't have a CRT monitor), you may wish to then test the cable connections to your computer. In some instances, simply replacing your monitor cable will resolve these types of problems.

You may also be encountering a problem where your monitor is simply set on the incorrect refresh rate. If the refresh rate is not correctly set, a monitor may display a "wavy" image or appear as if lines are periodically scrolling across the screen. Without knowing the exact make and model of your monitor however, I would not be able to provide any suggestions on how to change this setting - you would need to contact the manufacturer or refer to your owner's manual for specific instructions.

The worst case scenario would be if you are encountering an actual hardware failure. Both the video card and monitor can cause images to be distorted if they are not functioning properly, and even power supplies have been known to cause other components to sporadically malfunction. If you are unsure how to perform a hardware diagnostic, I would strongly suggest speaking with your local computer repair technician or a Geek Squad® agent at your local Best Buy™ store for further assistance.

Hope this helps you out.

Sincerely,
Aaron
