    Blue hue over video during playback on new monitors.

    Hello everyone;

     

    In our studio we've just installed some new DELL U2413 displays in one of our AVID Newscutter editing suites.

    The problem we are running into is that on video playback in AVID the video will display properly for a few seconds, and then after a while the while image appears to lower in brightness. It looks like there is some sort of blue overlay on the video playback window that actually expands past the window by a few pixels. The video display will go back to normal once the playback has stoped.

    I have looked online and cannot find anything like this, I've set up proper colour calibration and profiles in windows. I've been trying to figure out if it's a hardware or software problem.

     

    One thing I did try was having one of the new (U2413) displays and one of the old ( DELL 1901FP) displays connected and see if it happens on both monitors. As I thought, the problem only happened on the NEW display. One thing I found was interesting was that if I set up the two displays as a mosaic in the nVidia settings, the problem goes away.

    I'm at a complete loss as to what could be causing the problem. If anyone has any suggestions, please let me know. I've tested the newest display drivers (310.90) but that doesn't fix the problem

    System specs are:

     

    HPZ400 workstation

    Intel Xeon 3.33GHz CPU, 6GB RAM, Win7 64Bit, nVidia Quadro FX1800.

    Displays connected via 1xDVI, 1xDP (problem persists with 2xDP connections)

    Display Driver:275.89

    Newscutter: V10.5.2.1

    There used to be a problem where you'd get a noticeable shift in luminance between video playing and when it was stopped.  The fix was to go into the nVidia overlay settings and make adjustments until playing and stopped video matched.  If you search for "video overlay settings" you should find some more details about the problem.

    What do you think of the color on those monitors? When they're working that is. :) I've been trying to get a demo model to compare with our HPs.

    Re: Blue hue over video during playback on new monitors.

    I have played around with the settings for a while and can't seem to get anything to work.

    I've done a few more tests, and it turns out that this isn't something unique to AVID. Playing videos in Quicktime or VLC player produces the same problem.

    I have a feeling that this is something to do with the videocard processing the video, it always starts around the 20 second mark upon first playing a video.

    I know that the computer will offload video playback to the GPU to free up processing cycles on the CPU, so I'm guessing that when this happens, the video card is taking over the processing of the video.

    There must be some setting in windows or the nVidia control panel to change the video playback overlay settings.

    Note: The blue tint happens in other video players and it also extends past the video frame by a few pixels on each edge.

    Just wildly curious, doese the same thing happen with a different monitor?

    Re: Blue hue over video during playback on new monitors.

    It only happens with the new monitors I installed. I connected one of the old monitors (so we had one new and one old connected) and the overlay problem only happens when the playback window is on the new monitor.

    There you have it. It's the monitor. I found this in the user manual. I think it explains it.

    Uniformity Compensation adjusts different areas of the screen with respect to the center to achieve uniform brightness and color over the entire screen. For optimal screen performance, Brightness and Contrast for some preset modes (Standard, Color Temp.) will be disabled when
    Uniformity Compensation is turned On. When Uniformity Compensation is turned On, Energy Smart cannot be activated.
    NOTE: Screen Uniformity performance is optimized at default out of factory luminance setting.

    Smart Video Enhance
    Press the key to select the Smart Video Enhance "Movie" or "Advance" or "Off" .
    Smart Video Enhance automatically detects video (motion) in any window on the screen, and applies enhancements to the video. Only the video window is enhanced. Two different enhancement settings are available:
     Movie - suitable for movie or multimedia video clips.
     Advance - User adjustable setting.
    NOTE: Smart Video Enhance (SVE) enhances one of the video windows (typically the largest), if multiple video windows are active on the screen.

    Wow, I even read through the manual, but I didn't really think too much of that part. That was it. Thank's a ton for the help!
