My dad's PC has two monitors, but the integrated graphics from his processor stopped working. So, he used a HDMI cable and an adapter from DisplayPort to HDMI to connect the second monitor to his video card (a GTX 1650). However, the second monitor doesn't receive any signal, and, as he tries to change the Windows configurations, the informations seem to appear in the monitor which is not working (No Signal). What should he do to have both monitors working properly?
