When troubleshooting display devices, it is important to check the power. Ensure the display (and the system it is connected to) has been connected to the power correctly, that the power is safe and reliable, and the cables are in the right places (which can vary by device). Also, make sure the computer is in a good environment; the computer may not function well in a hot place.

Next, complete checks on the hardware and software. See if the issue is with the graphics card or graphics driver, and make sure the components included are compatible with one another. For software, check that the settings are configured correctly, such as resolution, size, and brightness settings or any other type of settings that relate to the issue. Some important tools for troubleshooting and analyzing the hardware and software can be Windows Advanced boot menu (which can boot into Safe Mode), Device Manager, and System Restore (if the situation requires a system restore).
