Unsupported Video Configuration is caused by having a graphics card installed, but connecting your display to your motherboard's display outputs. You need to connect your display to your graphic card's display outputs instead.

If you have the MSI GeForce GTX 1050 Ti GAMING 4GB you will need to connect your GPU to a 6-pin PCIe power connector from your power supply. Since the stock 790MT does not have this connector, you'll either need a different card that is exclusively powered by your PCIe slot, or purchase a replacement power supply.
