You can get a no display on your monitor for many different reasons. I’m going to show you possible solutions and how to roll out a hardware fault where possible. First let’s make sure that the monitor is not the problem.
Is your monitor set to the correct input? Look for the source or input button on your display.
If you don’t have one, the menu button will have it. Press the menu button and choose input, it switches over and problem solve.
If, for example, your monitor has HDMI input, you can connect any other device in your house that has HDMI to it to make sure it’s okay. Such as a games console. If you get display on screen, then you know, the monitor is all good. Check out with display cable you’re using. And if it’s firmly connected at both ends, you can also try another cable or a different type that your monitor and PC support
Again, you’ll need to make sure the input source is correct. A monitor that has no display from a couple of sources, and the correct input was chosen could be faulty. Try another input or a different monitor to see which is the problem.
If it is working fine and PC’s showing no display can be for a variety of different reasons.
For a PC that has a graphics card, check that the display cable is plugged into the graphics card and not the motherboard display port, which can be easily recognized by this type of IO shield. If you’re using integrated graphics with no graphics card to display cable should go into the motherboard display input.
Your PC may not be showing display due to the Ram sticks, not making a proper connection. If your mouse and keyboard are not getting any power, this could be the problem. Turn off your PC. Remove the power cable and open the case. First, try reseating the RAM back in its place.
Turn on your PC.
If there’s no display, unplug the power and try using just one Ram stick and resetting it. You can also try switching the sticks around.
Another option is to unplug the power, remove the CMOs button battery on your motherboard and press the power button to drain any left over power. Wait for a minute and then place the battery back.
See no display at all, could also be a faulty graphics card, but you’ll need to rule that out by trying in another PC as well. If possible, check if the power is connected to both the motherboard and the CPU. As well as the graphics card. If it needs additional power, reseating the CPU can help as well.
If it is hardware related, it could be the CPU, motherboard, Ram or memory, power supply or graphics card. You’ll need to rule out as many options as possible to find the issue.
I hope you get your display back up and running.
