    DisplayPort

    Anyone else using their DisplayPort (DP) regularly? A few days after I got my 5970 I decided to make use of the DP with my Dell 3008. One thing I noticed immediately was that it flickered a bit more during the POST sequence. Didn't think much of it at the time since it was fine in Windows 7. Then, just an hour ago the screen went blank in 2D mode. Not a big deal at first, known issue on some 5970's (driver bug). On reboot the vertical left half of the screen looked like CGA during POST and the entire screen was 4 colour mode on the Windows 7 splash screen.

    First thought, oh no my 5970 died, crap! Reseated the DP connection at all points but every hard reboot displayed the same symptoms. Flipped back to the reliable DVI cable and all was well again, no flickers, perfect colours. Switched back to the DP and flickers on POST came back but colours restored.

    Hmm.

    Anyone else have possible weak connection issues with their DP? The mini-DP connector on the graphics card looks suspect but don't have other DP device to test it. Guess I'll stick with DVI for now.

    Re: DisplayPort

    On my mac at work ive got 2 24" screens both running on display port without fault. Don't know what the advantages of displayport are.

    Seems like there are too many different graphics connections these days.

    Slightly more bandwidth than Dual-link DVI, supports audio, and mainly it's smaller and doesn't screws I think.

    From: http://en.wikipedia.org/wiki/DisplayPort

    Advantages over DVI

    - Slimmer cables and a much smaller connector that doesn't require thumbscrews. Connector pins don't run the risk of bending if improperly handled.
    - In low-light conditions or awkward under-desk connections, the DisplayPort connector is easier to connect when guided only by touch.
    - Based on micro-packet protocol.
    - Allows easy expansion of the standard.
    - Allows multiple video streams over single physical connection (in a future version).
    - Designed to support internal chip-to-chip communication.
    - Can drive display panels directly, eliminating scaling and control circuits and allowing for cheaper and slimmer displays.
    - Aimed to replace internal LVDS links in notebook panels with a unified link interface.
    - Compatible with low-voltage signalling used with 45 nm CMOS fabrication.
    - Supports both RGB and YCbCr encoding formats.
    - Auxiliary channel can be used for low bandwidth data such as touch-panel data.
    - Fewer lanes with embedded clock reduce RFI.
