Hi! My setup is: 1. Motherboard: ASRock X670E Taichi. 2. CPU: Ryzen 9 9950X. 3. Video Card: Gigabyte RTX 3080 Vision OC. 4. Monitor: ViewSonic VP2768-4K (27", 3840x2160p, 10-bpc) Annoyance: The resolution of the UEFI/BIOS menu is 1024x768. The BIOS menu offers 2 options: 1. "Disabled" = 1024x768 2. "Auto" = 1920x1080. However, whether I choose "Auto" or "Disabled", the resolution remains the same, at 1024x768. I've connected the monitor to the video card, both, through a DP 1.4 cable & an HDMI 2.1 cable. No change! I've taken out my video card & connected the monitor directly to the HDMI port of my motherboard, because the CPU has an iGPU. No change! I have set "Disabled" & restarted PC. No change! Then set "Auto" & restarted the PC. No change! A.I. tells me something about the GOP driver which locks my UEFI menu at that low resolution. ANY IDEAS ??? |

I have run into this myself a few times. In my case I had to try all the different display outputs on my system until I found the one that outputted in 1080p. Most cards have a default output that will be favored for 1080p output in the UEFI. If memory serves my last run in with this was resolved by using "output 0" on my GPU. It should be listed in your GPU's documentation. On one occasion I was unable to correct the issue at all until I used a different display cable (HDMI). DP has always worked for me though regardless of which output I use. Hope this helps. -------------

Hi! I have tried all of my DP & HDMI ports of my video card, but the issue is still there! Video card's ports revisions are: DP 1.4 & HDMI 2.0. Monitor's ports revisions are: DP 1.2 & HDMI 1.4. Cables used: DP 1.4 & HDMI 2.1. Note 1: I am on the latest firmware versions of my motherboard, monitor & video card. Note 2: Connecting the monitor to the iGPU, through the HDMI port of the motherboard, doesn't solve the issue! Final thoughts: ChatGPT says that the firmware of my GPU has a "GOP driver" that locks the firmware resolution to 1024x768. Changing the GPU (possibly with an AMD one) might solve the issue. |

Hi! I've wrote to the ASRock Support Team about the low resolution in the UEFI menu, issue. Their reply to me was this: "Hi, Thank you for your email. I'm afraid it is hard to solve this problem. Because under BIOS UEFI, GPU GOP driver resolution support is limited. Mostly, your GPU GOP driver will not report to our BIOS that it can support FHD. This is why our BIOS will only provide 1024x768. All the best ASRock TSD" I have replied to their response by saying that it's weird that the issue remains, even when using the CPUs iGPU, by connecting the monitor directly to the HDMI port of the motherboard. (So far, they haven't answered back). |

Hi! ASRock's 2nd reply: "Hi, Thank you for your email. iGPU also has its own GOP driver under BIOS. So it meets the similar behavior as dGPU. All the best ASRock TSD" After receiving their response, I've asked them back if buying a newer video card (RX 9070 XT or RTX 5080) would solve the issue. Let's see if they respond again! |

Hi! ASRock Support Team responded again. Their 3rd response: "Hi, Thank you for your reply This problem is related to the GPU and monitor compatibility. We are hard to guarantee that?switching the GPU can solve this behavior. All the best ASRock TSD" So, here we have it. No guarantees, at all, even with the newest generations of video cards! |

Hi! Yesterday I've bought a new video card: Gigabyte RTX 5070 Eagle OC SFF 12G. I've reset the CMOS of the X670E Taichi & I've re-installed Windows 11. However, the UEFI menu is still locked at the lower resolution: 1024x768. Conclusion: Newer generations of video cards do not solve the issue. |

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. All the best ASRock TSD" |

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!" |

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. All the best ASRock TSD". |

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." |

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! |

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  -------------

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 |

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! |

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" rel="nofollow - https://www.asrock.com/support/index.asp?cat=BIOS I hope that this will help someone... |
