Any new solutions regarding DVI (on D-sub VGA+DVI graphic cards) under QNX4 Photon?
Have you anybody succeeded in making DVI working under QNX4/Photon (vid/did/PCI index…)?
I have the same problem now - IPC in 19" rack and “remote” (several meters) LCD display (1920x1200), PS/2 keyboard and PS/2 mouse. In case of PS/2 keyboard/mouse we used 15 meters PS/2 extension cables, but no simple solution for VGA cable.
Any attempt to use longer cable (even high quality, thick, shielded, 2xferrite cores and only 3m long) leads to picture ghosts.
Strange thing is that the original HP (thin) VGA cable (1.8m) works perfectly - no ghosts, high quality picture in 1920x1200. Have you any explanation for that?
Yes, I know solutions with special hardware (analog to DVI converter or KVM through CAT5 “Ethernet cable” extenders - quite expensive for 1920x1200 resolution - and slight picture ghosts too), but all these solutions add some other (potentially unreliable) hardware.
