Can a regular CRT tv handle component?

[cherrcherryball]

Just wondering since if I connect a SVHS cable to my tv and select component out on my tv I get a really good quality pic compared to regular SVHS but its black and white.

And my maximum SVHS resolution is 1024x768 and with a VGA to Scart converter I can get over 1360x768 and thats officially, I have got a res of around 1600x1200 if I mess about with custom resolutions.

Can you explain a bit clearer what you're trying to do ? Are you sure you don't mean s-video, rather than SVHS ? Do you mean component 'in' on your TV or component 'out' on your source ?

I would imagine that only the more advanced CRTs with proper component inputs can handle a component signal (like my Panasonic 32PD30), but I'm no expert on the subject.

If you're trying to connect a laptop or PC to a CRT then all these higher resolutions will, of course, be unsuitable. In my experience, you'll actually have to lower the resolution to something like 800x600 (or even lower) to get a usable desktop with readable text/icons.

Yes a lot isn't clear.

I'm guessing that when the S-Video cable is attached (from what?) to the TV and Component Out selected (from the TV?) you're seeing, for some reason, just the S-Video Luma channel. That is the S-Video output minus the colour (Chroma).

How and why it is doing this and why it appears noticeably better than full colour S-Video I just don't know. However, I'd hazard another guess that the chances of you using this discovery to any useful purpose is nil.

I am using my graphics card on my desktop (hd4870 and q6600 pc) and selecting "force component detection" on Ati Catalyst. I think its in part regional settings as the PAL output of S video/svhs has loads of blurring and lines, and minor slowdown but if I select united states the picture is crisper with no interferance.

As for the convertor box I was talking about scrolling, the picture is crisp and clear with no interferance and proper RGB(as much as you can expect) but video movement seems to be missing say a frame or two in each bit.

Of course the text is harder to read at higher resolutions but thats not an issue since I want to use it for gaming and dvd's

I think this is likely a PC/Graphics card issue and you're more likely to find somebody who really understands and, hopefully, can offer a solution if you post about it in one of the more appropriate forums here.

My old Panasonic TX-36PD30 gives an amazing jaw dropping picture over component. I never tried it with hooked up to my PC though apart from via S-VHS.

Funny enough it's up for grabs in the classifieds as we speak

Can try to connect it to something outputing 1080i through component ? I've found this here: Tosh 36ZP48 at 720/768i!!! (maybe usefull for PD30/50s too)

I know this is a bit late discovery but nevertheless very interesting.
User seems to suggest that the high end Toshiba Panasonic range accept higher resolutions but you have to tweak the frequencies a bit.

Thanks

Hi ya,

I did once try 720p, 1080i and 1080p through the component cables but all i got was a rolling picture that would not even attemp to lock on.

It's now in storage in my brothers spare room so i'm not able to play anymore as it's a bit heavy at nearly 90Kg to cart around

I got exactly a rolling pic with my Tosh when I connected it to my PC with a VGA to component adapter (must be of the type that only does color space conversion). I lowered the timings/nr. of lines of the vertical blanking interval (using PowerStrip) to lower the Khz by a few decimals and it worked! The problem is that a PS3/Blu-Ray player etc. doesn't have the option to tweak the signal. The new version of the HDFury might do it though as it has a bunch of options to tweak the signal timings. It also translates HDMI to component with inbuilt HDCP

How's the dot pitch on the set ? I discovered that the tube used in the latest Toshibas was also used in HD models in the US (maybe Australia too). I bet some Panasonic HD CRTS on the US used the same tube the PD30/50 has.

Something like this may work for my vga to scart convertor since if I go to pal resolution like 640x576(or whatever it is) it wont work on 60hz on its own but if I change pixel rates etc it seems to stop blurring and work.

This may be a way to sort out the stuttering of normal video since I dont mind it being that res as long as theres no stuttering.
