Monitor displaying "NO SIGNAL"

I purchased an AOC 24G2 144Hz gaming monitor brand new and whenever I try to connect it to my motherboard it comes up with "NO SIGNAL". The HDMI cable I'm using is fine as I connected it to my laptop and my laptops display came up no problem. So I'm certain the actual monitor and the HDMI cable are fine which means it's something to do with my motherboard. I'm not too tech savvy so I can't even begin to start the process of elimination to find out the problem, which is why I'm here.

Computer specs:

MOTHERBOARD - msi B450-A pro MAX

POWER SUPPLY - Cooler Master MWE V2 650W 80+ BRONZE NON-MODULAR

CPU - AMD Ryzen 5 3600 6 core socket AM4 3.6GGz

STORAGE - Crucial 1TB NVMe M.2 PCIe 3 D NAND SSD CT1000 P1S

GPU - ASRock Radeon RX 5700 XT Phantom Gaming D OC 8GH V

RAM - Team T-Force Vulcan Z 16GB (2 x 8GB) DDR4 3200MHz

MONITOR - AOC C24G2 24" 144Hz
CASE - Cooler Master Master Box MB520 RGB Tempered Glass

 

Any help is much appreciated, cheers.

Is the HDMI cable plugged into the videocard, not the motherboard? (so it's in the horizontal ports)

connect it to your GPU, not your motherboard

 

 

-sigh- feeling like I'm being too negative lately

you mentioned "motherboard", on AMD systems you don't have an iGPU (generally) so it will not give ouput in ANY case.

If you have a dedicated GPU (as you do) you have to connect the monitor to the GPU and not to the motherboard (unless you do some sketchy ass shit like using a Tesla)

Main PC [The Rig of Theseus]:

CPU: i5-8600K @ 5.0 GHz | GPU: GTX 1660 | RAM: 16 GB DDR4 3000 MHz | Case: Lian Li PC-O11 Dynamic | PSU: Corsair RM 650i | SSD: Corsair MP510 480 GB |  HDD: 2x 6 TB WD Red| Motherboard: Gigabyte Z390 Aorus Pro | OS: Windows 11 Pro for Workstations

 

Secondary PC [Why did I bother]:

CPU: AMD Athlon 3000G | GPU: Vega 3 iGPU | RAM: 8 GB DDR4 3000 MHz | Case: Corsair 88R | PSU: Corsair VS 650 | SSD: WD Green M.2 SATA 120 GB | Motherboard: MSI A320M-A PRO MAX | OS: Windows 11 Pro for Workstations

 

Server [Solution in search of a problem]:

Model: HP DL360e Gen8 | CPU: 1x Xeon E5-2430L v1 | RAM: 12 GB DDR3 1066 MHz | SSD: Kingston A400 120 GB | OS: VMware ESXi 7

 

Server 2 electric boogaloo [A waste of electricity]:

Model: intel NUC NUC5CPYH | CPU: Celeron N3050 | RAM: 2GB DDR3L 1600 MHz | SSD: Kingston UV400 120 GB | OS: Debian Bullseye

 

Laptop:

Model: ThinkBook 14 Gen 2 AMD | CPU: Ryzen 7 4700U | RAM: 16 GB DDR4 3200 MHz | OS: Windows 11 Pro

 

Photography:

 

Cameras:

Full Frame digital: Sony α7

APS-C digital: Sony α100

Medium Format Film: Kodak Junior SIX-20

35mm Film:

 

Lenses:

Sony SAL-1870 18-70mm ƒ/3.5-5.6 

Sony SAL-75300 75-300mm ƒ/4.5-5.6

Meike MK-50mm ƒ/1.7

 

PSA: No, I didn't waste all that money on computers, (except the main one) my server cost $40, the intel NUC was my old PC (although then it had 8GB of ram, I gave the bigger stick of ram to a person who really needed it), my laptop is used and the second PC is really cheap.

I like tinkering with computers and have a personal hatred towards phones and everything they represent (I daily drive an iPhone 7, or a 6, depends on which one works that day)
