Monitor Why does my monitor come on and flashes the startup screen and then goes black?

Hope this helps.... Your monitor has an inverter issue. You know it's an inverter problem when:
1. Your monitor starts normally and displays the startup/desktop screen for a while.
2. Then it suddenly goes off, leaving a blank (black) screen or a very dim display.

To fix this black screen problem, change the inverter board (based on your monitor brand). Source(s): http://lcdmonitorrepair.annics.com

That is either the backlight or its power supply.

This is a bit tricky as you can get it fixed under warrenty but they will likely ask you to send back the entire computer not just the monitor. It is also something that you could fix or several shops could but the repair cost really isn't much less than a new monitor. You are not stuck using an HP monitor so anything will work and you can get quite a lot bigger or better for about $120 and up. Repair cost is going to be $80-$100 so as you can see for just a few dollars more you have a new warrentied monitor.

That's not monitor problem, it's your CPU, probably the Operating System crash!!!( Windows,etc).
Try reinstall it to solve the problem...

Try booting the pc in safe mode (press f8 at startup). It may be possible that the pc is trying to send too high a resolution to the monitor...unlikely though. The symptom you describe usually indicates that the power board or the inverter board in the monitor are defective. If it does the same thing in safe mode, you have 2 options.

1. Replace the power board and inverter board (do the inverter board first.......it's the cheaper one (10-20 dollars).
2. Send the monitor back to the seller for a refund, or get a new monitor.

Sorry I couldn't give you more positive feedback. Hope this helps.

Your monitor has a bad INVERTER, look on eBay.

plz log in safe mode and then disable the display adapter from the device monitor then log back normally and check whether problem is solved or not

I think you have the display shut off. the button on the bottom left will shut screen off. It will come on for a few seconds if you touch the screen, but will shut off again. just push the display button again and it should stay on.

there might be a problem in your monitor. replace the monitor with a new working monitor.

yes you can fix this problem go in to start menu then control panel then double click display, then screen resulution and add the secondary screen, bc windows doesn't add the screen automaticlly you have to do it this way

Sounds like you have a bad connection from your monitor to your computer. First check and make sure the connection between them is tight. Does your computer boot up and run though? If your computer is not booting up the monitor will default back to the flashing green power light
