I'm a first-time PC builder and I'm facing a frustrating issue: my monitor isn't detecting my new computer. Just to clarify, the monitor works perfectly fine with my old PC, so I'm confident that's not the problem. My friend, who assisted me in picking out the parts, suspects it might be related to the motherboard or that I may have connected some cables incorrectly. The good news is the computer powers on—the light is on and my liquid cooler starts up.
Here are the components I'm working with:
- B650E Asus Max Gaming WiFi motherboard
- AMD Ryzen 7 7700X (4.5GHz, 8-core)
- MSI MAG A750GL PSU
- Samsung 1TB SSD
- Corsair 32GB RAM
I've followed all the setup instructions, but I'm running out of ideas on what to try next.

I set up a drive folder that contains some photos of my setup:

Would appreciate any tips based on what you see!
Posting a few pictures of your setup could really help! Specifically, the connections on both the monitor and the computer would give a clearer view of what's going on.
Do you have a dedicated GPU, like an RTX 3060 or RX 7600, or are you running off of integrated graphics? That could be a factor in why your monitor isn't picking up the signal.
I had a similar situation last year! It turned out I had connected the display cable to the motherboard instead of the graphics card. It sounds like a rookie mistake, but it's worth double-checking to avoid it.
When you power up, does your motherboard show any lights? There should be indicators that light up during startup and turn off if everything's okay. If any lights stay on, that could point to a problem.
