What model are they?
What operating system?
Hi Buffaloboundsame problem on several TC. WYSE 5070 "B72GXN2". No signal on both DP connections. Screen is a Dell P2314Hc. TIA
Alonso. On a 5070 (not clear which OS) I would definitely say get a support case open.
the OS is win10, but cant see bootscreen.
Absolutely not normal. Get a support ticket open, and update us on the result.
Have you tried different cables and displays?
