Processors

Computer Setup:

CPU: AMD Ryzen 5 2400G with the Vega 11 native graphics

Motherboard: GIGABYTE GA-AB350M-Gaming 3 with updated BIOS to F22, this supports the 2400G

HD: Sandisk SSD PLus 240GB

RAM: Ballistix Sport LT 8GB kit (4gbx2), (BLS2K4G4D240FSB)

Here is my dilemma, I was never able to get a video output from this setup. I was, however, able to get a video output when installing my old 550 ti, that was part of the system that I was replacing with this set of hardware. I was able to do a fresh install of Windows 10 and get a desktop to boot with the graphics card added. I messed with the BIOS settings a little bit. I tried to force IGD, I used both auto and allocated video ram settings. I tried changing the RAM positions using 1 or two sticks in every combination possible. I tried using both the DVI and the HDMI ports on the motherboard, all without video output.

In retrospect, I did not find compatibility for this ram on the Gigabyte website. In the meantime, I did order a set of ram that matched exactly to the compatibility list. I will see if that makes a difference. It's just kind of strange that you can run the system with a graphics card but can't view anything without one installed. Does anyone have any insight on this issue?

Asus VP247QG monitor

I'm having the same issue, had to install a PCI-Express video card to get system up, without video card it told me monitor out of range. I have everything else up and running, installed both Asus and AMD drivers, it didn't help video,

guys - its your monitor

R5 2400G forces HDMI2.0 - but your screen only supports 1.4

my LG W2442PE has black screen - but when i use my AOC G2460PF it works fine

[kpbird]

I tried both HDMI and Display port, same thing.

[benman2785]

...
i do further testing now

can you try a different screen?

[kpbird]

I hooked it up to my TV and was able to get the latest Radeon Adrenaline driver installed. I am now able to get my Asus VP247QG monitor to display for Windows only, I get no display to the Windows logon screen, no display at POST. Thanks for your help. Any idea why I have no display at POST?

[benman2785]

for me it was the "cheap" cable - now with a good HDMI Cable it works fine

[kpbird]

Using cable that came with monitor, both HDMI and Display port.

[benman2785]

buy a good one - test it // i used the cable came with my AOC - did work on AOC but didnt work on LG

now with better cable it works on LG too

[misjah]

same issue, AMD Ryzen 5 2400g with ASUS Rog Strix x470-f gaming

are you sure about the cable, the specifications says : supports HDMI 1.4b max?

[benman2785]

as i said - i had this issue with my LG screen - but same cable worked with AOC
bought a good cable - now working fine on LG ,)

[chaswald]

I tried a variety of cables which varied in quality. I literally tried 4-5 cables with the Same result. No display at post. It was only after post and windows started up that the screen would fire up with the native Ryzen graphics.  I agree with one of the other responders that its my older TV that I use as a monitor. I can not confirm this because I don’t have another regular computer screen to try. But I haven’t found anything else that would indicate an issue. If I ever feel frosty I may attach it to a newer tv that I have in my living room to test it. Eventually I will get a computer monitor to replace it.

[benman2785]

maybe you tv doesnt support HDMI 1.4?

??? what you mention: no post but working when windows started = fastboot active?

Reset BIOS

[misjah]

i also got different cable HDMI 2.0b. and the result is the same. my monitor is Iiyama XB2483HSU-B3

[benman2785]

did you do any oc?

[misjah]

i have Win 10 Pro and everything is fine, my problem is, i dont see POST and BIOS when i start PC, monitor says 'Out of Range' !! .after that Windows is running perfectly

[benman2785]

...

you enabled fast-boot in bios!

do a cmos!

[misjah]

fast boot- normal boot, every time is the same

[kpbird]

I'm using a Monster 2.0 rated cable and still no post display.

[benman2785]

guys - do a CMOS

install flash bios

[misjah]

done everything and the result is the same.

Did anyone know what is the resolution and refresh rate on the onboard GPU?

[benman2785]

720p60 is common for bios

so: you boot your PC - and have NO SCREEN in Bios or while Windows Boots; but then, when Win is booted up you will have normal video output?
sounds like a wrong setting in Bios; or a not compatible screen - like HDMI 1.1 vs 2.0 incompatibility

also possible that your bios isnt latest version

as i said: i fixed it for the GA-AB350N-WiFi this way: i flashed latest bios and used an "Amazon Gold" HDMI cable on an LG HDMI 1.4 screen
but actually my problem was: Bios showed video and when Windows loaded driver it got out of range - because the old cable was 1.3a

i assume your error is either compatibility or wrong settings in bios

[misjah]

i'm using the latest bios, and cleared CMOS, the last cable i use was HAMA with 2.0b compitability

i wonder if i use the displayport on motherboard and displayport on monitor if this will work?

[benman2785]

mh - as far as i know: when you built the pc fresh - and power it up first time - many user claim that they needed HDMI for first boot
you can now try to use DP
for me DP worked everytime - but my LG screen doesnt have DP // yet it worked on my AOC
