compatibility issues with surface pro-11, Del K17A docking station and HP Compaq monitors

[FlyFifer]

connected new windows surface pro 11 to 2 x HP Compaq LA2405x screens and resolution is fixed at 640 x 480 and greyed out so I can't make any adjustments. Driver updates for both HP Compaq and Del docking station are correct.

Hi @FlyFifer,

Welcome to the HP Support Community!

Thanks for reaching out!

We're thrilled to have the opportunity to assist you and provide a solution.

Sorry for the inconvenience caused don’t worry let me help you.

Kindly follow the below steps and check of the issue is fixed :

Check Display Settings

• Go to Settings > System > Display.
• Confirm that both monitors are detected individually.
• If they appear as “Generic Monitor,” Windows may be using fallback drivers.

 Update Graphics Drivers

 Test Direct Connection

• Temporarily connect one monitor directly to the Surface Pro (bypassing the dock) to see if resolution options appear.
• This helps confirm whether the issue is with the dock or the monitor driver.

 Monitor Driver

• In Device Manager > Monitors, right‑click the HP Compaq LA2405x entry and select Update driver.

 Docking Station Firmware

• Check Dell’s support site for any firmware updates for your docking station, as outdated firmware can limit resolution output.

I hope this helps.
