1. Well swapping over the monitors did what I expected. Now the left one has a higher maximum resolution than the right (my monitors are the same make and model).

2. I'm not sure what you want me to do here. As mentioned I'm running Windows 7 on a MacBook Pro 13" (2012 to early 2013 model). How can I swap a graphics adapter that is internal and part of the main circuit board with my display link adapter connected by USB?

James please respond with some information. The lack of response is making me question the viability of display link products.

Hi,

I've just been trying to reproduce your problem.

I don't have a MBP running Windows but I do have a stock Dell Latitude running Windows 7 x64.

So far I tried a NL571AA HP adapter on a P2314H with 7.9 & 7.8 DisplayLink software and haven't seen this issue.

Could you try updating the Intel graphics driver for your notebook?

I'd recommend picking up the latest version.

If you have any issues with the graphics driver installation please see this FAQ:

Thanks,

Hey there! I am having this exact issue. Was there ever a solution?

I am using the NL571AA adapter with an Intel HD 4600 On board graphics.

Two monitors are 1080p but the DisplayLink adapter only goes to 1600x900.

I have tried many combinations of cable methods. My options per input are:

Monitor 1: VGA, HDMI
Monitor 2: VGA, HDMI
Monitor 3: DVI, DisplayPort

My computer graphics card outputs are DIsplayport and HDMI

The NL571AA has a DVI female end but I have many adapters available.

I have interchanged the adapter to each monitor and cannot solve the issue.

Please help it’s super appreciated.

Hello,

I understand my colleague created a bug from your ticket with the log files you provided.
Logs did capture the event properly: we can see the mode is recognised but removed as unsupported.
He will follow up on the ticket when engineering has done the analysis as to why this took place.

Kind regards,
Alban
