I do not see any new drivers from display link that will remedy this issue. Any suggestions I would appreciate.

I have this exact same issue. Everything was working fine with my Dell D6000 dock connected via HDMI to my Sceptre C35 ultrawide monitor prior to the MacOS update to 11.5.2 and now I cannot get the correct 3440x1440 resolution, I am stuck at 2560x1440.

Can someone with DisplayLink help with this issue?!

I am currently running an HDMI cable, but have ordered a DP cable and will report back to this thread if it corrects the issue.

For what it's worth, I switched from an 8K HDMI cable to a 1.4 DisplayPort cable from my Dell D6000 to my Sceptre 35" Ultrawide and immediately the problem was resolved.

I have full resolution now with the DisplayPort cable.

Glad you got it working , but I don't believe your issue is the same as reported in this thread - as you're only using one monitor and it sounds like you're monitor is connected via the hardware connection (HDMI) and not taking advantage of DisplayLink's software display. My guess is if you removed the DisplayLink software manager you'd have the same effect.

Mine wasn't working in 11.5.2 after the first update, but when I unplugged and used the Mac, then replugged it again (I don't think I needed to reboot) it started working again.
