It's my pleasure.


NOTE:

The new BIOS version isn't visible on the X670E Taichi official support page yet.

You can download the new BIOS file from this page of ASRock:

https://www.asrock.com/support/index.asp?cat=BIOS


I hope that this will help someone...

Hello!

I've updated the firmware of my X670E Taichi to BIOS version 4.10.

The low resolution issue of the UEFI/BIOS menu is gone.
Now, it's running correctly in Full HD, at 1920x1080.

Probably, the AMD firmware AGESA 1.3.0.0a solved the issue.

I've wrote an e-mail saying:
Thank you very much, to the ASRock TSD!

What ASRock would need to change to fix the 1024x768 BIOS resolution:


1. Update their UEFI EDID parser.

A proper EDID parser should correctly detect 4K/1440p displays and downscale to 1080p.


2. Increase UEFI video driver footprint ("GOP support region").

ASRock admitted this directly: "due to the ROM's size limit, the GPU GOP resolution compatibility is worse"


3. Update or replace their UEFI renderer.

Some other vendors use a more modern rendering engine that support proper DPI scaling, Hi-DPI fonts & multiple resolutions.


4. Improve compatibility logic (fallback rules).

Right now the logic is something like:
If EDID read fails OR resolution list smaller than expected =>
Fall back to 1024x768.

ASRock engineers could easily change that to:
If EDID read succeeds =>
Pick the highest resolution 1920x1080.
Else =>
Fallback to 1024x768


5. Test with a wider range of monitors

That is certainly a conclusion but it is incorrect.

I highly doubt ASRock allocates less BIOS ROM to GPU and display support than
other brands. ASRock was only stating that support is tricky given the space
limitation of ROM chips. They didn't even state if they were referring to the
board's BIOS ROM or the GPU's vBIOS ROM. It was a diplomatic answer, as we expect
from a manufacturer. They won't place blame or admit fault, this is normal in the
industry and part of the job rules for any tech staff at any manufacturer. They
would not risk their job and livelihood to tell a customer something that could
result in PR and legal headaches. At least they gave you an idea of where the
problem may lie.

Given you tried the iGPU and your dedicated GPU and both have the same issue
it would appear that your display uses an unsupported GOP and the GPU/iGPU
are not able to verify it's FHD support.

I don't know if it would be any different on another motherboard with the same
CPU and GPU. Basically there is a breakdown between the 3 different elements at
play. The Display, the GPU and the UEFI. A failure/compatibility issue at any
point in the chain will result in the same issue.

After all the time and effort you put in I am sorry you didn't get a solution

Hello!

ASRock replied again:

"Hi,

Thank you for your reply.

Our BIOS outputs the display depending on the GPU GPIO report.

GPU GPIO is the GPU driver under BIOS

However, due to the ROM's size limit, the GPU GPIO resolution compatibility is worse than the GPU Windows driver.

All the best
ASRock TSD"



CONCUSION:

The issue is not my monitor, my GPU, my iGPU, or my video cable (DP/HDMI).

The issue lies in ASRock's UEFI implementation!
ASRock allocates less ROM space to UEFI video initialization, compared to Asus, Gigabyte, or MSI!

With other words, ASRock admitted that their UEFI can't properly read the EDID modes that my monitor provides!

My reply to ASRock's previous response email was this:

"Hello,

Thank you for your reply.

I believe there is a misunderstanding.

My monitor does correctly pass 1920x1080 support in its EDID.
I verified this using CRU and other EDID tools.
Windows also reads this EDID information and allows 1920x1080, 1440p, and 4K without issue.

Therefore, the monitor is correctly reporting Full HD support.

Since both the GPU (NVIDIA RTX 3080, RTX 5070, and iGPU) and the monitor support 1080p, and since EDID is correct, the issue appears to be within the UEFI display subsystem or EDID interpretation on the X670E Taichi.

Could you please forward this case to the BIOS engineering team for further investigation?
This issue affects multiple GPUs and persists across different monitors, so it would help many users.

Thank you,
Best regards."

ASRock replied again, by blaming the EDID of the monitor (which is just a lame excuse):

"Hi,

Thank you for your reply.

This monitor can support 1920x1080.
However, it does not pass this information to the GPU, so the GPU cannot use this resolution in the BIOS.
Our BIOS will run 1024x768 if the GPU doesn't report that the monitor it is connected to can support 1920x1080 in BIOS.

Then, my reply back to the ASRock Support Team was this:

"Hello!

My monitor is Full HD compatible.

The ViewSonic VP2768-4K supports all of these resolutions:

3840x2160
2560x1440
1920x1080 (the one BIOS needs)
1600x1200
1280x1024
1024x768
etc...

So, the "not a Full HD monitor" excuse is invalid.

Please offer a BIOS fix for this issue to your customers!

Thank you!

Best regards!"

Hi!

The ASRock Support Team's reply to my email was this:

"Hi,

Thank you for your reply.

If the monitor is not a Full HD monitor, we cannot guarantee BIOS can work in Full HD resolution.
BIOS will use 1024x768 for better compatibility.
