sorry of I sound like a fool, but why would outputting video material at a higher res. than the material itsel make it look better?</font>

The same reason that people buy line doublers (and triplers and quadruplers) for their large format TVs ... minimize the gaps between the scan lines.

What is the max output (in resolution and refresh) does the G400max provide a television at this time?

Max resolution? Is the output De-interlaced?

Also, are progressive-scan DVD players de-interlacing? Meaning, they work with regular interlacing TV's, but have de-interlaced the image? </font>

TV (NTSC/PAL) is interlaced and NTSC max resolution is 450 lines. The signals delivered/received via composite and SVHS (Y/C) cables follow those TV standards. In other words, the G400 composite or SVHS outputs and your TV composite or SVHS inputs are limited by the NTSC standards. You can bypass this limitation by using the VGA output of your video card and VGA, component, fire-wire input of your TV (which is now acting like a monitor). Progressive scan stand-alone players use component inputs thus bypassing this limitation. Progressive is de-interlaced: All scan lines are displayed in a progressive fashion versus a frame being scanned down using every other line and then the second frame being displayed filling in the other lines.

Gotta break for lunch ...

My TV is limited to 480i. I am simply looking to use the component input on my TV. I need a converter from SVGA or S-video to a component input that my TV will accept.

480i would require 960 lines of resolution; your TV specs at 800. AFA cabling, you're wrong ... reread what I wrote. Seek out the web and learn about TV standards and video signals. I'm already blue in the face.

If you're asking for a way how to use the break out cable for a RGB connection to your TV, you should have a look at this.

I don't know if you can leave the adapter out, cos afaik is is detected by the card and without it, TV output mode is not accessible

At least I heard several times that the RGB connection would give a superior picture compared to s-video, so you might want to give it a shot.

[Maggi]

btw ...

NTSC = 525 lines overall, containing stuff like blackburst, synchronization etc, but only 486 lines of visible picture contents.

PAL = 625 lines overall, containing stuff like blackburst, synchronization etc, but only 576 lines of visible picture contents.

Both systems require (are based upon) an interlaced picture.

had to let it out ...

[ccoltas]

I was told by you that I could convert SVGA or S-video to component video, that is why I asked again about that. I know that it is probably not just a cable adapter or converter. Its the transcoder thingy. I just wonder if its worth it. Is it better than just going with my s-video connector.

Anyways, I appreciate all the info and I understand what you are telling me. The marketing is confusing.

Maggi, what you are talking about is kinda what I'm looking for, but like Xortam says, its not that simple. The BNC RGB connections on the back of my Samsung are not the same as component video inputs on the JVC TV. I'll look into it further though, just to be sure what the options are. I don't even know what a 'scart' cable is, unless that is the cable to hook up to a PC monitor with separate RGB connectors rather than the 15 pin SVGA connector cable plug.

I started out trying to find out what resolutions i could get etc, now I understand what the TV is limited to. Its a TV. So 800 lines really means 400 lines, right?

So here's a simple question for you then. What comes after the NTSC maximum? Is there an HDTV standard yet, or are there a few different resolutions? I have seen TV's with 480, 720, 1080 i or p. Is anything above 480 considered an HDTV?

Oops ... I made a couple mistakes. About NTSC lines of resolution ... you're right Maggi. I transposed the 450 lines from 540 lines. I'll go back and check why I thought BUD was delivering 540 lines vs. 525. Here's a chart showing various TV metrics:

            lines       active      vertical    aspect      horizontal  frame rate  
                        lines       resolution  ratio       resolution              
NTSC        525         484         242         4/3         427         29.94       
PAL         625         575         290         4/3         425         25          
SECAM       625         575         290         4/3         465         25

from "Conventional Analog Television - An Introduction".

480i requires 480 lines ... its 480p that requires 960 lines (I was just a bit tired of re-explaining things when I wrote that). U.S. DTV consists of a set of 18 standards as specified by the ATSC. HDTV goes all the way up to 1080p. Typically, HDTV is broadcast at 720p and 1080i. ccoltas, you're cabling is wrong. What I wanted you to reread in my previous post is quoted below:

<font face="Verdana, Arial, Helvetica" size="2">The TV will appear as a second monitor. You'll hook it up via the VGA connector, connect that to the VGA/DVD component converter, which will then connect into your DVD component inputs of your TV.</font>

I recommend that you search the web and do some reading instead of asking everyone to spoon feed you all this information. Search engines are a wonderful tool.

[ccoltas]

Search engines are a wonderful tool, but what does spoon feeding mean? Any time someone asks a question on a forum, they are trying to avoid searching the web and coming up with incomplete answers or dead ends. I have read 2 or 3 very good FAQ's about video but have yet to find a simple solution. I could try what you say about using dual-head as 2 monitors instead of a monitor and a TV, but after reading what you said about my 800 lines being only 400 lines, you confused me. Anyways, I honestly appreciate the info either way. I'm searching around the web and learning quite a bit.

have u tried to use the s-video on your tv i have a 32inch sony and am interested in knowing what the visual difference is between a component versus s-video...
please post agin if you seee anything significant

I am aware that the difference between S-video and component may not be great, but I'm used to the sharpness of 14-19" monitors and 20" TV's. A 32" TV by its very nature is not going to be terribly sharp, so I want to make sure the signal is as good as possible.

I pick up the TV today. I'll give it a try and let you know how the quality is with S-video. Until I find a way to use component, I won't be able to compare.

[Maggi]

follow the link I posted above and build your own RGB adapter (the adapter that came with your G400 provides all needed lines for RGB) ...

s-video will look much clearer than composite, but RGB should give you an extra bit more quality.

[ccoltas]

OK MAGGI, sounds like an idea. I checked the Matrox link out. The thing is, as Xortam was saying, my TV is analog interlaced. SVGA is digital progressive. Just changing the SVGA wiring into a component input would give me a Digital RGB like connection, right? I need the signal to be one thats compatable with the TV. It has to be very much like the S-video signal. I am only trying to separate it more. I do know that the Matrox settings do allow me to choose INTERLACED, and this might mak it work. It depends on the resolution, refresh (for TV must be only 60 HZ max) and the rest of the sync stuff.

I'm going to pick up the TV in about 15 minutes, so when I get it here I'll learn about the inputs that it does have.

I have learned alot in the last day or so AFTER I paid for my TV. I have learned that higher resolution progressive scan TV's the same size as my 32" JVC cost no less than 3 times as much as what I paid. I cannot afford that, so I'll be happy with this for 6 years until the warranty runs out and then I might consider HDTV set.

well, to put it short ...

attach the adapter, hook up your TV (using the pin connections provided by the link I posted) and reboot

Matrox made that part quite simple for you ...

[ccoltas]

I emailed Matrox tech support and they are not quite sure about my question. Asked me whether the composite needs sync on green and that if so the Matrox SVGA would not work. The info for the inputs on my TV are here:

Specs for the component input and S-video input, here's a comparison from the JVC TV owners manual:

S-video Input Jacks

Y: 1Vp-p positive, 75 ohms (negative sync provided)
C: 0.286 Vp-p (burst signal), 75 ohms

Component Input Jacks
Y: 1Vp-p positive, 75 ohms (negative sync provided)
Pb/Pr:0.7 Vp-p, 75 ohms

They look pretty similar anyways. Looks to me like its possible I should be able to make a cable to match it up? I check out the link you gave again. Which cable in the link am I to use given my TV inputs explained above???
