Fixing Issues With Crosstalk on AMD-based Platforms with 3D Vision

May 2nd, 2011 · 7 Comments · GeForce 3D Vision


It seems that some people using 3D Vision on systems based on AMD processors may be experiencing higher level of ghosting than normal and than people using Intel-based computers might have. There is a simple fix that could help in such situation that requires you to disable the USB 2.0 functionality of the USB controller (disabled the Enhanced USB Host from the Device Manager) where you have connected the 3D Vision IR emitter (you should not have other devices requiring high bandwidth connection). If you have an AMD based system and experiencing more crosstalk/ghosting than you think you should, then you can read the dedicated topic about the issue and the fix at the Nvidia forums. It is worth trying, have in mind that this will not change the situation for users of Intel-based systems and that some ghosting is expected to be present on pretty much all 3D-capable monitors. Anyway, if you do try that feel free to report if it did work for you or not as well as what your computer configuration is in the comments below.

    NICE!! Thank you Bloody! This FIXES the issues about 110-120Hz refresh rates described here:

    This even worked on my good old CRT! I wasn’t really getting that much normal ghosting but at max resolution (1920×1080@110Hz) I was getting a strange blue-tinted “horizon” hovering about a 3rd of the way down the screen, only visable through the nvidia glasses, but after disabling USB2 in the BIOS it has gone! I’ve also read that disabling CPU power-management features like C1E is supposed to help but it didn’t work for me. Thanks moneysocks!

    We have 3D Vision setups with AMD CPU & motherboards, but we are using Linux and utilize the 3 pin stereo plug on some Quadro cards, rather than the USB connection to the emitter, so this problem & fix is not relevant for us.

    This trick enabled us to have a perfect 3D image across the whole screen. Previously we had some ghosting/double outlines in the upper 5 or 7% of the screen (the rest of the screen was excellent) and we were considering this “normal” and living with it. Now every part of the screen, 100%, including top 10%, is perfect and displays rock solid, crisp 3D!

    Thanks a lot!

    Hello,

    I tried that too and it works for me!!! Now top 20 % of screen ghosting dissappeared. Thank you a lot !.
