Monitor displaying "NO SIGNAL"

Recommended Posts

Posted · Original PosterOP

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

 

 


Things I need help with: *new* Need help from "G-sync Compatible" monitor owner(s) / LF> specific Red/Blue Liquid

Spoiler

 

 

I hate Intel's pricing, Ryzen's weird quirks, Nvidia's pricing, and Radeon GPUs in general

 

Spoiler

 

Products I like:

Spoiler

Sony Xperia Z1 / Z2 / 10 ii, Asus Strix 970 / 1070, Samsung SSD, WD HDD, Corsair PSUs (AX, RM, CX(grey)), GeForce GPU, NZXT N450/S340, be quiet! Coolers, G.Skill Trident RAM, Logitech M525, Logitech G440, Razer Deathadder Elite

 

Products I hate:

Spoiler

Xperia Z3, XiaoMi 5c, Radeon GPUs, Razer Audio Products, any bloatwares

 

Companies I absolutely adore: (and hope it stays that way)

Spoiler

be quiet! - sent me AM4 mounting for my DRP3 even though it's way past the timeframe stated, no questions asked

Corsair - very good RMA experience, absolutely recommend

 

Companies I hate:

Spoiler

Nvidia, Intel, Apple, TMT (Thundermatch, a retailer)

 

Personal Blacklisted Companies:

Spoiler

Acer monitors, Gigabyte, Seagate HDD, Kingston SSD, Razer (except their mouse), XiaoMi Phones

 

Remember, just because I had good/bad experiences with these companies/product, doesn't mean you will have similar experiences too. I would still recommend these products if they made sense for your needs, but I'll add a disclaimer of my experience if it's relevant. Feel free to DM me asking why they are where they are.

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@5.0GHz | GPU 1: GTX 1660@2070MHz | GPU 2: GT 710 | RAM: 16 GB DDR4 3000MHz | Case: Lian Li PC-O11 Dynamic | PSU: Corsair RM 650i | SSD: Corsair MP510 480GB |  HDD: 2x 2TB WD Black | Motherboard: Gigabyte Z390 Aorus Pro | OS: Windows 10 Pro

 

Secondary PC [Why did I bother]:

CPU: AMD Athlon 3000G | GPU: Vega 3 iGPU | RAM: 8 GB DDR4 3000MHz | Case: Corsair 88R | PSU: Corsair VS650 | SSD: WD Green M.2 SATA 120 GB | Motherboard: MSI A320M-A PRO MAX | OS: Windows 10 Pro, Manjaro

 

Server [Solution in search of a problem]:

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

 

Server 2 electric boogaloo [A waste of electricity]

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

 

Laptop [A hunk of shit]:

Model: MacBook Air Late 2010 | CPU: Core 2 Duo L9600 | RAM: 4 GB DDR3 1066MHz | OS: MacOS Catalina 

 

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)
