Have you changed the input on the TV to whichever connector you are using,I’ve connected it to my LG 47" 1080p LED LCD Television
Are you happy you necro’d a year+ old thread with advice that was already given?If the BOOT LED is on with no display, the most likely issue is that your MSI B450M PRO-VDH MAX BIOS doesn’t support the AMD Ryzen 5 5500 yet. Try updating the BIOS, reseating RAM and GPU, clearing the CMOS, and booting.
