Do you have more than ONE video output/input connected to your monitor simultaneously?
Only use ONE for trouble shooting. If you have D-DVI or DP us that. D-DVI is better.
Reset your monitor display settings to factory default (just for testing).
In UEFI, F6, go to Advance menu and select Advance as your default UEFI menu,...AUTO for resolution.
Did you make any changes to the UEFI for display output? iGPU or PCI?
Shut down your PC. switch off the power supply, disconnect the power plug,....wait a minute or so or press the PC power button to discharge the power supply. Reconnect power cord, switch on PS and power up the PC.
Does the UEFI still show in 1024x768 with one video input connected?
