I have a Dell 1704FPT and a Radeon 9200SE Video card. The Monitor runs fine on analog @ 1280X1024 but as soon as I plug it in with a DVI cable it posts up green and boots up very scrambled and almost a light purple. I have changed and updated drivers for both the monitor and the video card as well as changing the OSD to Digital, even went so far as to get a new cable and nothing seems to work. This setup worked fine with the DVI cable for almost 2 years until just before I changed my mobo. I'm on training wheels when it comes to this stuff, is it the card, the monitor or what..any help would be greatly appreciated.

Quick, non-repeating diagnostic path and practical checks that were not covered yet — aimed at isolating whether the digital path (monitor input, DVI connector/cable, or the card's DVI encoder) is failing.

  1. Isolate hardware quickly: try the monitor with a different DVI-capable PC, and try the PC with a different DVI monitor or DVI-capable TV. If the fault follows the PC, suspect the video card; if it follows the monitor, suspect the monitor input.
  2. Inspect the connector and board: look for bent/missing DVI pins, corrosion, burn marks, or cracked solder joints around the DVI jack on the card or monitor. Power down and ground yourself before touching anything.
  3. Low-level software test: boot into the OS safe/low-resolution mode and force a standard resolution (e.g., 1024x768) at 32-bit color and 60 Hz. If the digital output becomes stable there, the issue may be a driver/refresh-rate mismatch; if it stays scrambled, it’s almost certainly hardware.
  4. Reseat and retest: reseat the video card, clean edge contacts with isopropyl alcohol, and test again. If the system had a motherboard change recently, also confirm BIOS/primary-video settings (integrated vs. add-in card) and reset CMOS as a sanity check.
  5. Final steps: if digital-only output remains corrupted while analog is fine, replacement of the faulty DVI encoder on the card or servicing/replacing the monitor digital board is the likely remedy.

A green/magenta tint on a digital feed usually means one or more digital color channels or TMDS lanes are not being received correctly; see the DVI overview for background on how the digital link works (Digital Visual Interface). Mentioning — checking color depth/refresh is a valid software check, but pair it with the hardware isolation steps above before deciding on replacement. Mentioning — document which combinations you tested (which other monitor/PC and which DVI cable) so any helper can avoid repeating steps already done.

My computer does the same thing as yours when i try to bring up anything related to my DVI cable and my internet. Everytime you start to use it right click on your mouse and click properties. Then click settings and look at the bottom see if the color quality has dropped down below 16 or 32 bit. If it has set it at the highest bit. I hope this helps you. Its the only solution I have found for my computer.

Thanks for your input. Next time I feel ambitious, I'll switch back to the DVI cable and give it a go.
