A short expert note tying together the thread: when a system shows video on one display but not another after a GPU swap, the usual root causes are connector/signal mismatches, the card being set to a mode the display cannot accept, or simple hardware/seat/power issues. was on the right track about connector types; the checklist below expands that idea into concrete checks and fixes.

Recommended checks and steps:

  1. Inspect connectors and the monitor OSD. A true "No signal" vs an "Out of range" or similar message gives different diagnoses (no link vs wrong mode). Confirm the monitor input selection and test the same cable on a known-good output.
  2. Verify whether the GPU output carries analog VGA. DVI-I carries analog pins; DVI-D does not. A passive DVI-to-VGA adapter only works if analog pins are present. If the GPU lacks analog output, an active DVI-to-VGA converter or a native VGA/DVI monitor is required.
  3. Determine whether the blankness appears before or after POST. No POST image usually means physical/seat/power problems (reseat the card, ensure any 6‑pin PCIe power plug is connected). POST visible but OS blank points to driver/resolution issues—boot safe mode or low‑res mode and reinstall correct drivers.
  4. Swap cables, try another known-working monitor, and test the questionable monitor on another machine to isolate the faulty component.

A final caution: always power down and unplug before moving cards or connectors to avoid damage from ESD or shorting. For a technical reference on DVI connector types, see DVI connector types.

Are you sure one of the moniters arent LCD? Check your video cards specs and see if it has a VGA port. If it does a CRT should work and the moniter your trying to use is busted. If there is no VGA it is most likely for .. forgot name of what you call it but you will need a LCD moniter or a new card.
