Graphics cards with Component video - anyone using?

Hi there,

I've spent the last 24 hours or so doing homework on the best way to
get video from my proposed Myth box into my telly, and I think that
by the time I've finished writing this email my head will be about
ready to melt.

Skip to the second half of this post if you're already using a
graphics card which features a component video output. (paragraph
beginning "more Googling, however...")

My TV is a rear-projection LG, model 44SZ21RD - had I bought a telly
with MythTV in mind I would undoubtedly have spent the extra to get
one with VGA or DVI in, but I bid on this at the last minute on eBay
in the hours following a recent Nintendo delivery, and it's only
since then that its occurred to me to try using it as an actual
gogglebox. From the point-of-view of buying a telly randomly without
regard to specification, then, I haven't been completely unfortunate
because this unit has 2 x component inputs and also 2 x RGB SCART.
With the amount of reading I've ended-up doing to try & figure the
best way to connect Myth I'm kinda kicking myself over not having
bought VGA, but at the same time it'd now be a lot of hassle to trade
up to that, and probably cost me quite a bit, too.

I'm guessing it would be easy to get RGB SCART into this TV if I
based a FE on an Xbox, or component from one of the upcoming Apple
STBs, but I really want to build a Myth box based on a standard ATX m/
board & case. I don't have a PC currently running 24/7 which could be
repurposed, and so I don't want the hassle of building anew separate
FE & BE machines.

What I'd really like to do is use a motherboard with onboard Intel
graphics, as I don't like having to use binary graphics drivers, but
I don't see it as likely to be able to find a motherboard with
onboard graphics and TV-out. As mentioned by Sean Darcy recently,
boards based on the latest Intel G965 Express chipset & with onboard
X3000 graphics can offer extended graphics-out options via an "ADD2"
card, but these cards don't seem readily available to the general
public; they seem usually to offer a second VGA or DHMI output, and I
can only find one OEM mentioning them in connection with TV use
<http://www.fujitsu-siemens.ie/Resources/201/730849794.pdf>.

My initial Googles for "vga scart" came up with a number of pages
about making a cable to connect from a PC's VGA out to a standard
SCART socket:
http://www.nexusuk.org/projects/vga2scart/circuit
http://ryoandr.free.fr/english.html
This is also mentioned on the MythTV wiki, however it's not clear
whether the Intel integrated graphics will do the appropriate
modelines <http://www.nexusuk.org/projects/vga2scart/>.

Does anyone know whether the Intel X3000 will support interlaced
resolutions & low dot-clock frequencies?
(14.76 MHz is mentioned for PAL)
<http://www.mythtv.org/wiki/index.php/RGB_Scart#Requirements>
For anyone who's interested in this there's a very long thread at:
<http://www.avforums.com/forums/showthread.php?t=136811&page=1>

I think it was somewhere in that thread that I stumbled upon mention
of the new (at the time of the posting) ATi All-in-Wonder X800 which
sports funny dongles for component & SCART TV-outs. <http://
www.hexus.net/content/item.php?item=852>. I don't believe the All-In-
Wonder to be ideal for MythTV because of the state of ATi drivers
under Linux - a local supplier lists this model at 130, but I'm
unlikely to use the tuner as DVB-T reception is poor in my area (I
plan to get a separate PCI card for DVB-S).

More Googling, however, has turned up a number of other cards with
component outputs. Is anyone here using any of these?

Abit RX600 Pro-HDTV (ATi chipset) - <http://tinyurl.com/yfdbgs>

BFG GeForce 6600 GT OC - <http://www.beyond3d.com/reviews/bfg/
6600gtoc/index.php?p=2>, <http://www.bjorn3d.com/read.php?
cID=774&pageID=1405>

BFG GEFORCE 7600 GT OC 256MB PCIe - described as having an "HDTV
connector", presumably this is the same as the component dongles
shown in the reviews of the 6600 above; I can find this model for
about 100 on eBay.

PNY Verto GeForce 6600 GT 128MB AGP - <http://www.hexus.net/content/
item.php?item=1166&page=3>. The manufacturer's website appears to
describe this as a "HDTV-out breakout pod" <http://www2.pny.com/
6200-128MB-AGP-P1723C15.aspx>

My local supplier offers number of other PNY cards which appear to
offer this "HDTV-out breakout pod":
http://www2.pny.com/6200-128MB-AGP-P1723C15.aspx - 37
http://www2.pny.com/7600-GS-256MB-PCIe--P1777C14.aspx - 53
http://www2.pny.com/7300-GT-256MB-PCIe--P1895C14.aspx - 62
and others at prices exceeding 100, more than I'd prefer to pay for
a graphics card.

Am I right in thinking that nVidia cards are better than ATi for
Linux / MuthTV use? I detest binary drivers, but that's less hassle
than messing with a homemade cable - if I have to accept binary
drivers then I'd prefer the card / chipset that's best-supported
under Linux and likely to be longest-supported.

At the moment I'm thinking that one of the PNY Verto cards will be
the way to go; the last remaining thing is to see if this component
"HDTV-out breakout pod" is supported under Linux. Anyone?

But I also made such a long posting because I wanted to lay out all
my thinking along the way. I don't see any solution which is optimal
to my preferences, but I'd be glad for anyone to knock me down if
I've got things wrong.

Thanks in advance for any comments,

Stroller.

Graphics cards with Component video - anyone using? [In reply to]

Hi there,

I've spent the last 24 hours or so doing homework on the best way to
get video from my proposed Myth box into my telly, and I think that
by the time I've finished writing this email my head will be about
ready to melt.

Skip to the second half of this post if you're already using a
graphics card which features a component video output. (paragraph
beginning "more Googling, however...")

My TV is a rear-projection LG, model 44SZ21RD - had I bought a telly
with MythTV in mind I would undoubtedly have spent the extra to get
one with VGA or DVI in, but I bid on this at the last minute on eBay
in the hours following a recent Nintendo delivery, and it's only
since then that its occurred to me to try using it as an actual
gogglebox. From the point-of-view of buying a telly randomly without
regard to specification, then, I haven't been completely unfortunate
because this unit has 2 x component inputs and also 2 x RGB SCART.
With the amount of reading I've ended-up doing to try & figure the
best way to connect Myth I'm kinda kicking myself over not having
bought VGA, but at the same time it'd now be a lot of hassle to trade
up to that, and probably cost me quite a bit, too.

I'm guessing it would be easy to get RGB SCART into this TV if I
based a FE on an Xbox, or component from one of the upcoming Apple
STBs, but I really want to build a Myth box based on a standard ATX m/
board & case. I don't have a PC currently running 24/7 which could be
repurposed, and so I don't want the hassle of building anew separate
FE & BE machines.

What I'd really like to do is use a motherboard with onboard Intel
graphics, as I don't like having to use binary graphics drivers, but
I don't see it as likely to be able to find a motherboard with
onboard graphics and TV-out. As mentioned by Sean Darcy recently,
boards based on the latest Intel G965 Express chipset & with onboard
X3000 graphics can offer extended graphics-out options via an "ADD2"
card, but these cards don't seem readily available to the general
public; they seem usually to offer a second VGA or DHMI output, and I
can only find one OEM mentioning them in connection with TV use
<http://www.fujitsu-siemens.ie/Resources/201/730849794.pdf>.

My initial Googles for "vga scart" came up with a number of pages
about making a cable to connect from a PC's VGA out to a standard
SCART socket:
http://www.nexusuk.org/projects/vga2scart/circuit
http://ryoandr.free.fr/english.html
This is also mentioned on the MythTV wiki, however it's not clear

I am using a GeForce 6200 based card (not sure on the exact mfg/model)
with the component out cable thingy, and it works just fine, if you use
the right config. When I first tried it the display was not right (no
red signal) and I couldn't get it working. I left it for about 6 months
then finally resolved myself to getting it working, and did. You have to
specify an HD resolution in the 'TVStandard' option of the xorg/xfree
config file. For me, since I have an SD TV with component input, that
option is 'HD480i'. Not sure what yours would be, but you should be able
to make it work. Since I've done that, and a few other tweaks, I have a
beautiful picture.

I've got a nVidia GeForce 6200 with the HD (component) break-out pod and
I have yet to try using the component video. I, too, have been
periodically browsing around to see what might need to be done to get
the component video working correctly, but, since it wasn't high on my
list just yet, I haven't approached it.

Would you be willing to share your config with the list as sort of an
example? :)

Oooh! I figured I'd learn more about X11 configuration if I Googled
"TVStandard"... lo and behold: <http://www.mythtv.org/wiki/index.php/
ComponentOut>

I'm surprised by the author's statement "utilising a VGA to component
transcoder provides higher quality". Can anyone explain why this
might be, please?

I think I'd be quite glad to use standard on-board graphics and a 60
adaptor box, but had assumed that X11 could scale the image better -
the panel in my telly has a native resolution of 720x576 & does 576p
(@ 50hz, I think).

Not sure, since my personal experience is that with finally getting the
component out on the Nvidia card to work, I have the best Myth display I
have ever had, and that is with using composite, s-video, 3 different
VGA transcoders, and finally the component out. I can't see how my
picture could get any better at this point, for me anyway. I'm sure my
setup is far from normal though.

If 576p is a standard HD definition, then you should be able to use
'HD576p' as the the TV Standard in xorg.conf.

Sure. I did many things to get the picture and performance that I have

My TV is SD but supports 576p via component. However, if I use HD576p
the picture is scrambled and corrupt and the TV clearly can't sync to
it. HD576i works fine though.

Really frustrating since I got the 6200 card specifically to do
progressive out :(

Are you sure it supports 576p? My SDTV supports 480i, but not 480p.

Yes. It's a Panasonic TX36PD30 which claims to do PAL progressive.

Googling "TVStandard" I find a table [1] which lists "PAL-B" & "NTSC-
M" as parameters for this option, but not any of the hi-def modes.
Presumably this is because the article in question is based on nVidia
TV-out over S-Video or composite.

What refresh rate is "HD480i", however? LG claim my tube does "480i/ p
(60)/ 576i/ p(50)/ 720p(50/60)/ 1080i(50/ 60)" [2] - I presume the
"50" AND "60" are in these cases hz?

How are you specifying 576p?

I would find that frustrating, too. :( In my case I know
specifically that my telly has an digital panel in it 576 pixels
high. I just wish I could address that more directly.

Many thanks for your comments. I find myself with somewhat more
confidence in them than in the article I liked to, and am tempted to
give this a try.

Does anyone have any comments on which graphics card I should choose?

PNY nVidia 6200 128meg AGP @ 37
http://www2.pny.com/6200-128MB-AGP-P1723C15.aspx
PNY nVidia 7600GS 256meg PCIe @ 53
http://www2.pny.com/7600-GS-256MB-PCIe--P1777C14.aspx
or PNY nVidia
http://www2.pny.com/7300-GT-256MB-PCIe--P1895C14.aspx - 62

There's a big bit of me that says "get the cheapest card" but another
part of me thinks I should "invest" in newer PCI Express technology.
Of course when I start going down that route I start admiring the
specifications which indicate the more expensive card to have a fill
rate of nearly twice as many billion pixels per second. :/
Presumably the 7x00 cards can be expected to be longer-supported by
nVidia's binary drivers that the 6x00 series?

> I'm sure my setup is far from normal though.

What's normal? Especially in MythTV. It seems to me that connecting a
monitor to a PC is easy! With MythTV we make our job so much more
difficult, insisting on connecting to television sets which were
designed quite without computer connectivity in mind.

Cheers,

Stroller.

No, because the mode needs to be one of the HDxxx ones as this forces
the TV-out chip to use the component rather than the svideo connection.
The component out uses a different colour space.

I am guessing that the internal modeline for HD576p is incorrect in the
driver.

Thanks. That's very useful to know, as I am very tempted by a nVidia-
based card with component-out.

:(
I'm assuming that you're using the nVidia binary drivers; in this
case I guess the bug may be expected to affect all cards with a
nVidia-based chipset & a component-out. :(

Is it possible your telly accepts PAL progressive only through RGB
SCART? And not through component?
I don't know if this is fair conjecture or not - someone slap me if
RGB SCART is by definition limited to interlaced input.

I'm just doing some homework on this, and I think this may be an
explanation:
<http://www.mythtvtalk.com/forum/viewtopic.php?
p=12424&highlight=#12424>
<http://www.hifi-writer.com/he/progscan/progscan.htm>

From what I'm reading 576i via component may give the best picture
on my telly (which, as I've mentioned before, has a 576 panel). To be
honest I don't know if this'll be discernible from 480p and allowing
the TV to upscale, but it's what I'm inclined to go with.

I'm beginning to find tellies, and tv technology in general, to be SO
frikkin' legacy. Makes me wish I'd just bought one with a VGA input
in the first place.
