nVidia: *better* TV out quality?
Hello all, I am using sid w/ X 4.1 and use the latest nVidia dirvers and kernel module interfaces. I use a Toshi 3000-100 laptop with a Geforce2Go w/ a Chrontel TV out chipset. TV-out works fine so far, but i would like to get to know your experiences. What is disturbing is this (on the TV device): -screen width not fully used (two black borders left and right) -distorted picture on sharp contrasts (e.g. on detailed pictures), looks like flimmering blue spots -bad colours, even when adjusting i cannot get nearly the colours as seen on the display anyone knows about X settings or filtering software that can smooth the picture. I primary use it for watching DVDs using TV-out, as long as i got no standalone hardware DVD player :-( *g Right now i am searching the web for specs, but most software hints etc. touch the windoze world :0( Your experiences with GeforceX TV outputs??? Thanx for any hints and comments. greetings, Timo

Kill the [EMAIL PROTECTED] low quality lowpass filter the typical board makers add, and your image will be much sharper... Search google for details. This is a function of whatever board manufacturer (and model, and revision) you have, not only the TV out chipset, and the GPU core has very little to do with it. Oh, and use a low resolution (640x480, 800x600), unless you have professional high-res equipment connected to the board.

Thanx for any hints and comments. This is not a Debian/Linux thing. The problem is that nVidia TVOut sucks. See the latest article on tomshardware.com for more instances of this. Seems it's a long running complaint w/ nVidia Cards. There's a site that has a tool for workarounds in the Windows world at www.tvtool.com . Other than that I would suggest ATI if TVOut is that important to you.

Should have added that i use PAL (germany), i dunno the exact chip, should be a Chrontel 7001 or 7002. Timo

Is e.g. Mozilla a Debian/Linux thing as often discussed here??? :0) Okay, let us get serious here: I was wondering if maybe a free software package oriented to this problem is out there that maybe hang itself into X or framebuffer, so having nothing to do with nVidia etc. On the other hand, the Chrontel seems to be very spread, thus not affecting nVidia only. The problem is that nVidia TVOut sucks. That's true in some way. See the latest article on tomshardware.com for more instances of this. Seems it's a long running complaint w/ nVidia Cards. Was not there for a long time, but thanx for the tip, i will consult the page. Other than that I would suggest ATI if TVOut is that important to you. From a software's point, over the years i had serious problems with ATI cards, no matter what OS (Win, Lin, BeOS, FreeBSD). And it is hard to exchange the VGA of my laptop :-). Thanx for your hints and kind regards, Timo

I have a ELSA Gladiac 311 (NVidia GeForce2 MX DDR rev 178). I have no idea how I can use the TV out port. Can you hint to a document or anything how I can use the TV out. What do I need to get the DRI working? Bye, Steffen

I just had to set DGA (loadmodule) once for a TV card (ALDI, die Monokarte :-)) had to be run. If not already, the first step is to get the latest binary drivers from nvidia.com-drivers-linux, use the dist-independent tarballs and follow the instructions in INSTALL. After make has been done (installs the binary drivers and compiles installs a kernel module interface as well as documentation). Insert NVdriver into /etc/modules to autoload the driver module each sysstart. The doc under /usr/share/doc/nvidia has several docs and X samples, including one dedicated for TV out. Besides that, here some excerpts from my X config for minimal config and use (== no extra features like twin view etc.).: # add this section for your second display devide, i.e. the TV Section Screen Identifier ScreenTV Device NVidia GeForce Monitor TV DefaultDepth 24 SubSection Display Depth 24 Modes 640x480 ViewPort 0 0 EndSubSection Option TVStandardPAL-B #germany Option ConnectedMonitor TV EndSection # add this section and uncomment it to use the TV as output device and # restart X # normally, uncommenting it can be avoided by starting X with the # serverlayout param, but this did not worked for me :-( #Section ServerLayout #Identifier UseTV #Screen ScreenTV #InputDeviceStick CorePointer #InputDeviceKeyboard CoreKeyboard #EndSection good luck, Timo
