Possibly related observation: On my 720p TV, if I output (via HDMI) 720p to it, I lose the outer ten or so pixels off of each side of the screen. NVidia video card configuration tool indicated a higher resolution was available, 13??x???, which resulted in a fine picture with no missing pixels, once I switched to it. This was about a year ago. (Can't easily test, now, because I no longer have a PC hooked up to that TV) -- :wq

--snip-- The TV is an LG 47LH90 and and it is said to do 1080p.

BUT often the wires between them are too long or there are two or even more end points. Result: HF from near by broadcast stations, 60Hz mains frequency, ham radio station, microwave ovens and anything which can emit energy, pushes protective earth to another electrical potential than 0V. Since both, PC and -- in your case -- the monitor are using protective earth, they may be put on another, may be even varying (over time) electrical potentials. Since they are connected via a two-wire connection WITHOUT protective earth (no, the shielding is not for that purpose) the difference in the potential earth put both ends to different electrical reference points. This way you get an amplitude modulation of the signal between both endpoint. In case of 60HZ you will hear a Brummschleife sound on audio connection (a buzzing sound), in case of frequencies near those of the video signal you will get ghosts in the monitor picture. Now, how to avoid that. Hit the one who have made the protective earth connection in your house. While you are searching for that person, you can try the following: Put all mains connectors of you PC rig into ONE wall connector with something like this (ok I miss some words here again and since a picture says more than even thousands of /missing/ words here comes an image of what I mean:): http://www.reichelt.de/Steckdosenleisten-ohne-Schalter/6-FACH-DOSE-WS-5/index.html?;ACTION=3;LA=2;ARTICLE=108651;GROUPID=4281;SID=11Thz@On8AAAIAABaBBrE9f5418078c2ea9fe6608e9765d978595 This way, all protective earth ends up in the same contact. No differences in the electricla potential of the protective earth anymore. Why does the those USB-isolatore-like cables help here? These small air core

Good luck! :) Best regards mcc Thanks for that. I'm still working on it but adding radeon.audio=0 to grub cleaned it up about 75%. - Grant
Re: [gentoo-user] Problem with xf86-video-ati nvidia-drivers
Grant emailgr...@gmail.com [11-07-10 01:42]: When I was using an Nvidia video card, I noticed a strange sort of fuzzy edge effect if I used nvidia-drivers. xf86-video-nouveau didn't have the same problem. Now I've switched to an ATI video card and unfortunately I have the same problem with xf86-video-ati. I tried to enable the new modesetting radeon driver in the kernel to see if that would help but it doesn't work with my HD4250 card yet. Does anyone know how to fix this? Here's a photo of the effect around the mouse cursor: http://imageshack.us/photo/my-images/804/cursor.jpg - Grant Hi Grant, just a shot in the dark: The image looks to me as thos would be an analog instead of an digital problem. May be both propietary drivers switch to the highest possible data transfer rate and this triggers the problem. To check, whether this may be the problem: Instruct the driver to use either low resolution or low refresh rates. Check both. If the problem changes signifiently: Change the cables. May be only a pluf is not inserted correctly. Addtionally you can move the cables arround to see whether this will change the shadows around the cursor in any way... Good luck! :) Best regards mcc
