Question Resolution Settings with Quadro A5000

[eco_bach]

Have a Dell 27" 2560x1440 monitor. With my A5000 and latest Quadro driver I cannot reach this resolution in Windows 10 Display settings.
No issues if drive my display from my older Titan Volta installed on the same PC.
Could this have something to do with using a Display Port to HDMI adpater?

using a Display Port to HDMI adapter?
Mind sharing a link to the adapter you're working with? Which Dell panel are you working with?
