TV out for Xorg/OpenBSD?
Hi, We have this BSD box with some films on, and someone had the idea of hookiing it up to the TV so we can watch DVD's etc in the living room. Not a bad idea, but I don't know how. My friend bought a VGA->Scart cable, and I have tried various resolutions and various horizontal and vertical ranges without luck. I asked a friend who is into this sort of thing and he reckoned [EMAIL PROTECTED] is a good start, but the best I have had is a messed up picture with diagonal scan lines moving down the screen quickly. If you google you get links to linux "howto's" for the proprietary linux drivers, so no thanks to that. I wonder if anyone knows a way. -- Best Regards Edd http://students.dec.bmth.ac.uk/ebarrett

You need an interlaced [EMAIL PROTECTED] mode. A suitable modeline should be findable with google.

You can try some of the modelines there and need to make sure the tv is in rgb mode and the sync-line ist connected and put's out the right singal. http://www.unix-ag.uni-kl.de/~pfeffer/tvout/index.html Alternatively most modern cards have a tv-out, don't know what is supported by the x-servers. The solution using RGB above will give the best picture quality if you get it working. -sm
Re: TV out for Xorg/OpenBSD?
Howdy! Eons ego I recall using klone language to make appropriate ModeLine for Xfree conf file. Also, some scripts live inside si- milarly named directory to help that process. lso, take a look at this faqs: http://www.at.openbsd.org/faq/faq11.html#XF86 Hope this helps. Zoran

Its the type of cable which usually goes into the yellow socket next to the red and white audio ones (yah, i dont know a thing about this stuff). I have a cable hooked up to this aswell as vga, with no results. All I can think of is that I will have to look in the menus for related settings *if* i can find the right remote. UNtil now Im using another sony remote, which happens to work, but not for menus. The TV is a Sony KD-28DL11U The card is a "NVIDIA GeForce4 MX 420" rev 0xa3 -- Best Regards Edd http://students.dec.bournemouth.ac.uk/ebarrett

It's likely not interlaced and you need the interlaced signal for the tv. Most LCD and CRT screens nowadays are not capable of syncing down to the 15.625KHz of the TV-Signal. modeline "pal_768x576" 14.75 768 784 864 944 576 582 588 625 -hsync -vsync interlace # H 15625 [Hz], V 50 [Hz] modeline "pal_720x576" 13.875 720 744 808 888 576 582 588 625 -hsync -vsync interlace # H 15625 [Hz], V 50 [Hz] You can check the X-log to see if the card actually accepts the modeline and uses it. If you put only this resolution into the config it should either start with it correctly or drop out with an error. Then I would use an Oscilloscope to check the signals on the Scart-Connector to make sure you have what your TV needs. Maybe somebody from the electrical-engineering department at your university can help you with that. I had something like that running in the past, but since I don't have a TV anymore... ;) -sm

Well the x1550 (and other x1*** too probably) should work, but since these are all assumptions you might want to do some googling.. My friend had PCI-e version but I don't think it matters. I can ask about some details about configuration when he gets back online.. I've been trying to get AGP version myself but they're all sold out here in Finland. I've been searching for x1650 because the x1950 (or something like that) is way too expensive for my taste. -- Antti Harri

I found that works out quite a bit better, but of course it's more investment. Just bought a Samsung 2032MW 20inch monitor. Has all connectors, VGA, DVI, SCART, video... has a tuner. Has PIP, you can watch TV and you PC session simultaneousy. For just 199 Euro. Larger models, sold as TVs, mostly have all connectors too, just that the "TV"s don't have Picture In Picture, while PC monitors do. Now PAL 720i (720 horiz * 2x288) is broadcast quality: the signal sent by the station. "Good" home TV's can differenciate 360 horiz signals. VHS tapes are in the 360/240 area. A good starting point for PAL TV might be 360*288 at 50 Hz or 360*576 at 25 Hz interlaced.

Edd, Could you post (or privately email) your xorg.conf and X.org.log I don't know a thing about S-Video and have never heard of "Scart" before, but we might be able to get the TV Out (Composite Video) working on that card with the default driver. At one point in time, the TV Out on nVidia cards was handled by a separate chipset (brooktree/conexant/philips/?) but I doubt that is the case on GeForce4mx and newer cards. None the less, the trick with cards that have multiple outputs is making sure you're talking to the right output. The nv(4) driver will try to auto-detect if an output device is connected (monitor/TV/?) but it may not get it right and may default to the wrong output. There are two things you can try: 1.) Force access to the TV Out interface through the BusID (see xorg.conf(5)) BusID "PCI:1:0:0" # or BusID "PCI:2:0:0" 2.) Force access to the TV Out interface through CrtcNumber (see nv(4)) Option "CrtcNumber" "integer" You can often coerce (force) video cards with multiple outputs to play nicely even when they are such total garbage that the vendor (nVidia) is afraid to provide specifications for them. There is one issue I see that might be a problem, namely NTSC versus PAL but a lot of TV sets these days can accept either, so we might get lucky. If not, the PAL modelines you posted look reasonable. Kind Regards, JCR

Re: TV out for Xorg/OpenBSD?
Hey guys, I think I know what J.C. Roberts is looking for, but alas it is hard to find. I also purchased one of these vga -> svideo cables, and it truly is just that, some form of converter from vga to s-video with no logic inside. So, you have to have the perfect sync on the vga side to make the picture show up nice on the TV side. I never got this to work. What I have found is lots of video adapters have a builtin s-video port, which works for displaying videos on the tv. With one huge caveat. Out of the 5 cards I have that do s-video out, two of them pci 'ATI Mach64' cards, only one (one of the 'ATI Mach64' cards puts out a signal that looks decent. Some of them put out signals that flicker and never sync, others put out signals that color shift or do other visual eyesores. So, if you really are on a low budget, find a used computer store and get some Mach64 card or some other card that has a known good s-video output signal, and enjoy your movies. Me, personally, I'm looking forward to saving up for a widescreen (2-3 years out at best) that has a vga/dvi input for a computer to display to directly without the s-video limitations. Until then, I enjoy lots of video files in my living room courtesy OpenBSD. Have fun, P.S. Edd, if you do have a resolution that works with the VGA->S-Video cable, I suggest posting it here on the mailing list, there will be a use for it to be in the archives I am sure. -- Todd Fries ..

Hi Edd, People on misc@ are interested, but I suspect there will be a fair amount of back and forth, and there's no guarantee we'll get it to work, so there's not a lot of point in flooding [EMAIL PROTECTED] If we get it working, then we can post the results and full xorg.conf onto misc@ and not cause a lot of stir. If possible, please enumerate your conf files (xorg.conf-1, xorg.conf-2, etc.) and email them to me. If you have the X.org.log files for them, it would help, but a description of what you get for each would suffice. Both connectors and connections are a pain. If you could take a snapshot of the card connections, the adapter cable/connectors, and the inputs on your TV, I'll be able to see exactly what you have. I'm actually afraid to go digging for a picture of the card on the net, because there's no guarantee it will be what you actually have (sadly, even if it's the same part number). I do believe I have a newer nVidia card around here someplace, but I have no idea where it is, what it is, or if it works. It was a freebie I got that had a dead fan (which they no longer make/sell), but I replaced the fan with a wee bit of modification. For some reason I'm remembering it to be a GeForce4 card of some sort so I'll try to find it tonight. A dmesg would be appreciated. --If I can replicate your hardware environment to some degree (save for PAL, I'm in NTSC land), it will make life easier. Kind Regards, JCR

Re: TV out for Xorg/OpenBSD?
TV outputs and standards are quite simple, but apparently some explanation might be in order. Since we're already off topic, I'll just try to summarize some facts regarding things mentioned in the thread. To start, when talking about baseband video outputs, a TV standard (PAL, NTSC, etc.) defines two things: the video timings and a color encoding. Normally, a TV out encoder will take care of all of that and output a suitable baseband signal, but that requires your video card's and its driver's cooperation. FTA (for the Americans), SCART is a european standard AV connector with 2-way composite video, audio and one-way RGB and S-Video signalling, plus a few data wires that can be used to synchronize the channels tuned in your TV to your VCR. In the case of a VGA to SCART cable, you need to create a modeline of [EMAIL PROTECTED], so the HorizSync is about 15kHz, while VGA monitors usually support only down to around 31kHz. The color encoding is totally irrelevant with RGB, you just need to coerce your video card and driver to output the right frequency. I unfortunately have only done this years ago, in Windows, using PowerStrip. You will probably also need to pull up one or two pins in the SCART connector (8/SWTCH to 12v and 16/BLNK to over 3V) to put your TV into RGB mode; I've had lots of European TVs that are pretty picky about the voltage. You may also need to experiment with sync polarity, and depending on your cable, with composite sync (you need it since SCART has only one sync pin, but the cable may already wire HSYNC and VSYNC together). The SCART RGB way can be painful, but the image quality is worth it (look at the TV's built in teletext and compare it to a composite video signal). Someone also mentioned a VGA to S-Video cable with no intelligence. Those are usually used in laptops with cooperation of the video hardware. A simple modeline will not make your video card output S-Video. -- Jussi Peltola

Re: TV out for Xorg/OpenBSD?
Hi Making a cable up is straight forward the only problem is the soldering is fiddly - you need a very small soldering iron. You should probably also get a multimeter to test your soldering before using the lead in case you fry your telly or graphics card. Here are two websites on how to build it: http://ryoandr.free.fr/english.html http://www.idiots.org.uk/vga_rgb_scart/ Use the pin connection table from the first site not the second. They are M$ biased so ignore the software parts Peter Edd Barrett wrote: Hi On Wed, Aug 20, 2008 at 8:46 AM, Jussi Peltola <[EMAIL PROTECTED]> wrote: You will probably also need to pull up one or two pins in the SCART connector (8/SWTCH to 12v and 16/BLNK to over 3V) to put your TV into RGB mode; How is this achieved?

Eh? My LCD is marked as 16:9 and 1440x900 is native resolution.

(1440 / 810) = (16 / 9) = 1.77 (1440 / 900) = (16 / 10) = 1.6 There is a check box on that form to restrict the aspect ratio. If you checked off 16:9 but still entered a 16:10 resolution, then it would only generate the modeline for a 16:9 resolution, which happened to be 1440x810 in your case. I also do not know if you're referring to a LCD TV, or a computer monitor. It's quite possible your LCD physically is 16:9, but still has a 16:10 input resolution and the picture is scaled appropriately internally. For example, my LCD TV seems to only allow 4:3 resolutions on the VGA input even though the physical aspect ratio is 16:9. It will take a 1400x1050 resolution and scale it to fit the full screen (1920x1080). I have to use 'mplayer -monitoraspect 16:9 ...' to prevent videos from being displayed as a stretched out and misshaped 4:3 image.
