The connecting cable or the video card would be the first suspects. Try a different cable to connect the monitor first, if there is no change, the video card in the computer would be second to look at. Can simply connect a different monitor to your computer to troubleshoot this. If the testing monitor works, it will be the graphics card that is the issue.

If your motherboard doesn't have a VGA connection, then that means it most likely does not have an integrated video card. If this is the case, then you will have to purchase and install a video card. It is very easy and your local Best Buy should be a great resource. The geeks there are usually very enthusiastic about explaining how to do it. I use to order from newegg.com, but they have become very commercialized and overpriced, like Best Buy. You can check tigerdirect.com or my favorite Amazon.com. Best Buy will price match any items they sell, including those on Amazon. If you need further help, I’m available over the phone at https://www.6ya.com/expert/jason_3e83613ef5f2a68b

I would suggest trying your xbox on another monitor to be sure the xbox is not the problem.

you need to give a bit better details as to what is happening

Most new LCD tv and monitors color,brightness,vert.hold, horz.hold,resolution, ect., are all controlled by a single programmed EEPROM, that costs more to replace than a new monitor/tv. You pay for the programming, not the chip.

Change the cable and check.

Once you power off the monitor you will have to turn it back on. If you keep it in standby mode it will come up once you turn your computer on.

You can boot from a source other than your hard drive, a usb stick or a bootable cd. then use the format command to erase the hard drive. You are now good to give it away. If you need further help, I’m available over the phone at https://www.6ya.com/expert/michael_e0539de310ea5ad7

This could be because the menu button is faulty contact Samsung support and they will help

Does this monitor use a separate AC power converter/power supply? If so, unplug from monitor, and test voltage on the output plug. Had a similar problem, it was the power supply, NOT the monitor.

You should have given us the Model, but see if this helps... http://forumserver.twoplustwo.com/48/computer-technical-help/where-power-button-samsung-syncmaster-t220hd-monitor-321111/

Click the menu button on the monitor.

bad power supply, a blown out transistor,diode, but check horizontal output first.. take it out, then test again,,if its stops ,and power light comes on,, then change h-output transistor.

Potential Problems: Cables One possibility is that your cables are messed up. The 15 pin connection cable could be malfunctioning. You should get a new cable and replace it to see if it helps your situation. If not, the problem lies somewhere else. Environment There could also be an electromagnetic interference affecting your computer. You should move the laptop around the building or room to see if the position of the monitor changes the flickering. If it stops when you change positions, then there is something in the virtual environment affecting your monitors ability to display properly. Display settings If your display settings are improperly set, then your screen could flicker as a result. You should go into your desktop main screen, click Properties > Settings > Advanced > Monitor, and set your screens refresh rate at around 85 hertz or less. Video card The other possibilities are that the video/graphics card that was integrated into your computer has stopped working. You should switch it out with a new one to see if this helps your situation. Monitor Try to plug your monitor into a different PC/laptop. If it works properly, then you have an internal computer problem. You should also update your monitor's drivers just in case.

No. No monitors do (that I have ever seen). If you think you have seen one that does, it was more likely an all-in-one computer.
