QDM-9WD-121 Siemens monitor is one of the earliest generation Siemens monitors. This monitor was fitted on Siemens 3, 3t, 3m. The QDM-9WD-121 is a 9″ green monochrome CRT based display. DNC has been offering exchange and replacement on this monitor since 1994.

We offer two solutions, both of which are plug and play compatible. Either a brand new complete CRT replacement with a 12 month warranty or an LCD replacement with a 2 year warranty. Both options are excellent. The replacement for this is aptly named the DNC 9S1. The CRT is slowly being phased out, due to dwindling stocks of parts to manufacturer it.

The replacement for this is aptly named the DNC 9S. We can do either a CRT based DNC 9S1 (which we are phasing out) @ POA GBP (1 Year warranty – While stocks last). Or new DNC 9S1 replacement which is LED based @ £ POA GBP (2 Year warranty). The replacement DNC 9S is an equivalent replacement monitor for the Siemens QDM-9WD-121 monitor.
