Thanks for the update grysqrl. Clearing CMOS before powering up a newly built system
is always a good idea. ]]> Mon, 30 Sep 2024 21:49:18 +0000 https://forum.asrock.com/forum_posts.asp?TID=69154&PID=153120&title=display-doesnt-work-when-gpu-installed#153120 <![CDATA[Display doesn't work when GPU installed : Update for anyone who is looking...]]> https://forum.asrock.com/forum_posts.asp?TID=69154&PID=153119&title=display-doesnt-work-when-gpu-installed#153119 Author: grysqrl

Update for anyone who is looking for this in the future: Clearing the CMOS worked. I have no idea why, but things seem to be working now.]]> Mon, 30 Sep 2024 21:44:49 +0000 https://forum.asrock.com/forum_posts.asp?TID=69154&PID=153119&title=display-doesnt-work-when-gpu-installed#153119 <![CDATA[Display doesn't work when GPU installed : I am building a new computer using...]]> https://forum.asrock.com/forum_posts.asp?TID=69154&PID=152595&title=display-doesnt-work-when-gpu-installed#152595 Author: grysqrl

I am building a new computer using a Z790 Riptide board. The power turns on fine - all of the lights and the fans go on. However, when I try to connect a monitor to the HDMI port on the motherboard, it doesn't get a signal. I tried the same cable/monitor combo with another computer and it worked fine.

One thing I tried was removing the GPU (a Geforce RTX 4070 Ti Super) and then the display started working and I was able to get into the bios. When I reinstalled the GPU, it stopped working again. I've tried a couple different power adapter cables to connect the GPU to the PSU with no change.

Any idea what's going on? What should I try next?]]> Sun, 29 Sep 2024 11:32:16 +0000 https://forum.asrock.com/forum_posts.asp?TID=69154&PID=152595&title=display-doesnt-work-when-gpu-installed#152595
