[NAME]  Yes. The WD19TB when paired with a Thunderbolt system like yours can run dual 4K 60 Hz displays, and 3440x1440 is less resolution than 4K. The system’s GPU is also capable of handling 4K displays. So a single 3440x1440 display will be completely fine.
Hey guys  Wonder if someone can help? I currently have an XPS 9305 (1920 X 1080) with a WD19TB docking station. I want to buy the Dell 34" Curved Monitor - S3422DW Dell 34 Ultrawide WQHD Curved Monitor - S3422DW | Dell UK Would I be able to run the monitor that has an ultrawide WQHD (3440 x 1440) resolution without it displaying in a letterbox style? Thank you.
