DeepSeek PC on two monitors: fix blurry DPI (2026)
On mixed 100%/150% displays, DeepSeek desktop can look blurry when dragged to the sharper screen.
Set the app to use the primary monitor scaling, or match both displays to the same scale for coding sessions.
If fonts stay soft, close the app, change Windows display scale once, then reopen so the window restarts cleanly.
Keep the chat window on one screen while docs stay on the other; avoid stretching a single window across the bezel.
After the UI looks sharp, pin your default model again so long R1 runs do not surprise you mid-task.
