Screen is on but it is just a blank screen - No input

If your screen is on but it is just a blank screen then it does not have an input of visual going into it. Please try the following:

- Press the "input" or "source" button to cycle through the inputs as it may not be set to the correct one. 

- If you have multiple screens your PC may not be duplicating its screen, press Windows key + P on your keyboard and select duplicate to duplicate your screen.

- Check the cabling, see the "Image appearing yellow/green below" as it is the same steps.


Image appearing yellow/green

If your image is appearing yellow/green then this could be the cause of a faulty port on the monitor or cable.

- Ensure that all cables are secured properly as loose cables can cause problems.

- Look for any visible damage.

After checking these, the technician may need to replace cables or ports themselves. It could be a computer driver issue potentially which your technician will need to look at.

Below are some images of cables and splitters to help you identify them:

If you have tried the above and if you have issues with your screen where it doesn't look right or if you have a touchscreen device that doesn't respond to touch inputs, you can reset the Display Driver using the following Keyboard Combination:


CTRL + SHIFT + Windows Key + B 


If you have speakers you'll hear a beep and your screen will flash black once and your display will reset.
