Mai x470 gaming plus 

gtx 1660ti

ryzen 7 2700x

vegence 16gig 3200mhz

corsair 750w psu 

So this is a build with all new parts that I decided to assemble on my own and the computer oosyed first try and I actually downloaded a driver and played one benchmark game (csgo) and than it was time to transport the pc home which was done very carefully, now the entire pc will power up and all fans/RGB are powered except there is no display from either ports. I also tested other cables and my gpu in a different computer and it worked. Any guidance in the right direction is appreciated.

After I ran through checking each cable I had a friend that built his own pc double check, I also tried the CMOS button and different ram slots.

Try using the mobo's display output sometimes it gets switched( I have no explanation for this) but in newly builts the sometimes default output is from the mobo which has to be changed to gpu

For some reason it once was working through the normal hdmi on the gpu
