A good monitor connected to a good computer can t show what s wrong

It's mostly a matter of resolution. The monitor does not have self-resolution adjustment. On the old machine, the resolution of the old machine is 1024*768

can be normal reality. But to the notebook and the new machine. The graphics card supports a high resolution, and your laptop and new computer are set to a higher resolution than the one supported by this monitor.

So if you plug it in, it won't be displayed. You can try to set the resolution of your laptop and new computer to the same as your old one. Remember to align with your old computer.

See if you can show it!

Hope mine helps you! Thank you!

First of all, initialize the monitor settings, and then check whether the power supply and ** cable have been connected. If it doesn't work again, check if the graphics card is damaged. If it is a discrete graphics card, you can plug it into the graphics card of the machine's motherboard and test it. If it doesn't work anymore, you can only apply for repair.

It should be a matter of resolution, try turning down the resolution of your computer.

You first change the display that you can see, change the resolution to 800x600 and then change to the monitor that doesn't work to see if there is an image. If there is, go into the system and slowly adjust it back.

You can re-install a universal graphics card on your computer, install it in your taskbar and see it, click on the MVIDIA control panel, and once you're in it, you'll see the display on the right. Display multiple monitors, but before you can link your monitors.

Adjust the resolution to see if it's okay.
