W10 HD 630 driver issue at 3440x1440

[asapuntz]

Asus Z170-E motherboard w/ i7-7700K (HD 630 GPU), W10

Motherboard HDMI out produced 3440x1440 with LG 34WL75C-B for 1+ years using "standard" W10 HD 630 and Generic PnP monitor drivers.

In July 2021, LG went away, W10 upgraded to 21H1. Connected (same HDMI cable) to Acer ED347CKR bmidphzx. Video is vertically squashed, best available resolutions is 2560x1440.

Updated monitor driver to ED347CKR, Intel graphics driver from 23.x to 30.0.100.9684, several HDMI cables, no improvement.

Only thing that "works" is to disable HD 630 driver in device manager, but W10 reverts on reboot.

Hello asapuntz, 

In order to investigate further, I would like to confirm the following:

1. Are you able to customize the resolution with the Intel® Graphics Command Center?

- https://www.intel.com/content/www/us/en/support/articles/000056144/graphics/legacy-graphics.html

2. Have you tried with a different monitor?

3. Are you able to try with a different computer/laptop connected to the Acer ED347CKR bmidphzx?

4. Have you contacted Asus to confirm that the monitor is compatible with the motherboard?

1. Intel GCC makes custom settings available. I haven't found a set that works

2. As stated in the original post, LG monitors work fine.

3. Yes, a 2015 MBP (DP) and a Dell Latitude 5420 (HDMI) work fine with the Acer.

4. What would make it compatible?

Some observations of the EDID detailed timing descriptors:

LG has 3440 modes that run at 319.75MHz and at 265.25MHz

Acer has a 3440 mode that runs at 533.12MHz

What are the limits of HD 630 vs Iris Xe?

Hello asapuntz, 

In order to continue further, I would like to confirm the following:

1. Are you trying to run 3440x1440 at 60Hz or 24Hz? Are you able to try at 24Hz?

2. Are you able to confirm if the current HDMA cable is a 2.0 version or try with a 2.0 HDMI version? We recommend trying version 2.0 since it has enough bandwidth to display the resolution wanted.

Also, here you can see the graphics details of the Intel® HD Graphics 630 and Intel® Iris® Xe Graphics:

1. Intel® HD Graphics 630:

- Max Resolution (HDMI)‡ 4096x2304@24Hz

- Max Resolution (DP)‡ 4096x2304@60Hz

- Max Resolution (eDP - Integrated Flat Panel)‡ 4096x2304@60Hz

2. Intel® Iris® Xe Graphics:

- Max Resolution (HDMI)‡ 4096x2304@60Hz

- Max Resolution (DP)‡ 7680x4320@60Hz

- Max Resolution (eDP - Integrated Flat Panel)‡ 4096x2304@60Hz

1. No 3440 modes are offered by the Intel GCC when connected to the Acer. I think you already have the EDID info from the display, maybe you can suggest alternate settings?

With the LG, I believe it's running at 50p. 23, 24, 25, 29, and 30 are in the refresh rate drop-down on the General tab, but they produce "squashed" images. Information tab shows 3440 modes with 50, 60, and 85Hz.

2. I have no way to test HDMI cables other than to demonstrate that they all work fine with the Dell Latitiude 5420 / Iris Xe.

Don't know if Max Dynamic Freq correlates to bitclock, but Xe max is <20% better than 630.

Hello asapuntz, 

Based on the investigation, looks like the driver for the Acer monitor are very old (for Windows 8), I recommend you to check with Acer and ask for any new drivers and try one more time.
