DK0701 3rd monitor on VGA is now only giving a maximum resolution of 1280x720. It has always been 1920x1080 like the 2 on HDMI as well until recently. Video drivers are fully up to date. I was attempting to install the DK0701 driver as well, but it fails with: Fail! ErrorCode:0xA (Enter Isp Mode fail!)
Any ideas on correcting this 3rd monitor over VGA? I am not using the DP port because my 3 monitors are hooked up to my desktop via DP. HDMI from 2 and 1 other VGA (using HDMI to VGA adapter) so I don't have to swap cables on 1 monitor constantly, just the inputs on the monitors.

Hi @Matt McCutcheon，
Okay, I got your question.
In order to analyze the problems you encountered, I have a few questions that I need you to provide:
1: What is your computer brand model and DP version?
2: Have you done any other operations on your computer before this problem occurred? For example, there were 2 external monitors before, but now there are 3 external monitors; whether your system has been upgraded, such as upgrading win10 to 11.
3: Please provide the SN number of the product (usually on the back of the product).

1. HP EliteBook 840 G8 and DP version, if you mean Display Port version, this laptop doesn't have a built in DP port, only HDMI. The Dell S2417DG monitors are DP 1.2 and HDMI 1.4.
2. I upgraded all the drivers on the machine, including the graphics driver. This is when it started. It had worked fine with 1920x1080 on all 3 monitors until this and it forces that 3rd montior now to only use 1280x720 for it's max. However, I had my IT department update my BIOS today as well on this work laptop to see if there is any difference.
3. I'll have to check the SN when I get home and around to it. I'll update this if the BIOS update may have helped or not as well.

Well. Wait for your SN number.

I've kind of gotten used to just using the 2 monitors though anyway. Leaves my 3rd open for my desktop to play games or search for whatever that isn't blocked on the VPN for work lol. It's too bad though I couldn't trade this model in for a discount on one of the newer ones that have 3 HDMI ports now like I had wanted to begin with since my 3 DP ports on monitors go to desktop, not the laptop.

Hi @Matt McCutcheon
Have you solved the resolution problem before? For example: have you updated the computer's BIOS, etc.
As for the discount you mentioned, you can send me the link of the model you want to buy. If we have a promotion, we will notify you.

Yeah, BIOS was fully updated, all drivers. The problem started after actually updating some drivers on this laptop as it worked great right from the start using all 3 monitors at 1920x1080, 2 HDMI and 1 VGA w/ the HDMI adapter. I may actually be getting a refresher machine soon anyway, so maybe it will work then again :) I was kind of joking on that discount thing, I may need a 2nd one anyway later down the road too. I am sure the whole problem is that HDMI adapter and I just got lucky at the start there of it working.

Hi @Matt McCutcheon，
You can try again as follows：
1: Roll back the graphics card driver
Operation: Open the device manager - display adapter - right click the graphics card driver - there is an option to roll back - click the program2: After the first step, install the file we provide.
