I finished building my PC recently. when I turn on the monitor when the computer isn't on, there's obviously no signal and I see the bouncing logo, but when the computer is on, it says that there is no signal, and that my monitor is going into standby mode, and the display turns off. my gpu seems to be working fine, and I reseated my ram. What should I do?
Haven't seen this mentioned, but did you make sure to plug the display cable into the GPU and not the MoBo?
edit: nvm, just saw a comment with same suggestion
I have done this. My CPU has an APu so even if I didn't it would be a non problem
Have you tried to connect it to the MoBo then? If nothing appears on the display even then, the problem is somewhere else than your GPU.
Also, does the display have more than one input? Have you chosen the correct one from the display?
