So youвЂ™ll only run into this program if you are using an older version of Windows or a really old monitor. Also, Windows normally detects the highest resolution your monitor can support and shows only those options. In most modern versions of Windows, the system actually reverts back to the original screen resolution within 15 seconds unless you click on the Keep Changes button. Once you have gotten the computer into safe mode, follow my instructions here on fixing the blank screen issue because of screen resolution. To fix this, youвЂ™ll have to start Windows in safe mode first. Sometimes if you accidentally set the resolution in Windows higher than what the monitor supports, it will simply go blank. Method 3 вЂ“ Check Resolution, Display & Source If using VGA works, then it could mean there is an issue with your HDMI or DVI cable. Try replacing the video cable or using a different video cable if you have multiple connections options like DVI, HDMI, etc. If the screen is blank on the second monitor also, then it could be an issue with the video cable. To do this, you need to find another monitor to connect your computer to. If the cables are connected and you only have one video connection, then you need to rule out bad cables. If you have dual monitors and you connect one to the motherboard and one to the graphics card, then one monitor will end up blank and now you know the reason why. Restarting may fix the problem, but itвЂ™ll happen again. If you end up connecting your monitor the motherboard, it might work for a little bit, but suddenly go blank. By default, Windows is supposed to disable the motherboard graphics automatically when you have a separate graphics card, but sometimes this doesnвЂ™t happen. If you have a dedicated graphics card, then make sure the monitor is connected to the graphics card and not to the motherboard video connection. For those of you who have more than one video card, you need to be careful how you connect the monitors.

Make sure you check the connection at the PC and on the monitor.

This is especially true for cables that donвЂ™t screw into the back of a monitor. Whether you are using VGA, DVI, HDMI or DisplayPort to connect your computer to your monitor, cables can sometimes become detached. The next easiest thing to do is to check all the cables. If none of that works, try restarting the computer by pressing the power button. Try pressing keys on the keyboard or moving the mouse.

If the power is on and everything looks fine, but youвЂ™re still not getting anything on your display, the computer may have gone into standby or sleep mode and isnвЂ™t being woken up.

You will have to reference the PC manufacturer manual to figure out what the beeps or status lights mean.

The beeps can also be related to the motherboard, video card, etc.

You can read my previous post on how to test your computer for bad memory, which can be one cause for the beeps. If the power button or one of the status lights is red or orange or if the computer beeps several times when turning on, this is indicative of anВ internal problem. The main thing here is to check for any warning lights or unusual beeps when you power on your computer. Now check to make sure the computer is properly turned on. Try replacing the power supply and see if that fixes the issue.

If a separate monitor works fine, then it could mean the power supply is bad on the original monitor. Even with nothing connected, you should be able to bring up the monitor menu.В Try connecting a different monitor if you have one. If still you have a blank screen, then this could mean there is a problem with your monitor. If the monitor is on, but nothing is showing up, try to press the menu button to bring up the built-in monitor controls. If the light is on, the monitor is on and you should see some message. Check to make sure the monitor is turned on, which is usually indicated by some kind of light on the power button itself. YouвЂ™ve probably already done this, but itвЂ™s still always worth mentioning because it happens more often than you would think.
