I believe it may work, but...
This interests me too.
I was also wondering whether it was possible to get component video through this socket?
If anyone could shed any light on this and the IScan then that would be most helpful.
I suspect that the FD1 will ot accept componet YUV through it's VGA socket, more than likely only RGBS and RGBHV.
The Iscan Pro should work on it, though expect only upto 848x480p, which would discount PAL pro-scan.
I don't think there is any cable component<>vga.
I contacted silicon image but had no answer yet.
As the svga socket seems to be an rgbhv (from the service manual schemes) it should work fine with the iscan pro.
The problem is to know if the set can accept directly a 768*576 resolution without passing by the 800*600 (svga) mode. If it is not the case we will have a 4/3 letter box image, which means a little smaller than a 28" with black borders all around because the full mode in vga-svga only enlarges the width.
1-is it possible to activate the 16/9 ratio via the menu service in PC-in input?
2-is it possible to make the tv accept directly a 768*576 resolution?
it might be possible to plug
DVD in component socket
VCR in composite socket
SUB tuner (2nd tuner) un sVideo socket
...of the iscan
does it seem crazy?
Kary.... if the device will accept 576P@50Hz RGBHV signal then your idea is sound...I doubt it will though.
If it accepts 640*480 and 800*600 why wouldn't it accept direct 768*576? There's something I don't get there. Might be an electronical incompatibility or ...?
The refresh frequencies are from 50 to 75hz in 480 and 600 acording to my computer videocard. In the menu of the set another frequency appears, I don't know what it is, it's variable. All I remember is 800*600 at 75hz/48khz
The other thing is that the set accepts higher resolutions even if lines are missing, so it should be possible to play blindly with the missing lines to center and resize the image?
It goes up to 1280 (limit of my videocard) but half of the screen is missing.
would it be dangerous for the tube or the electronic?
Here are the resolutions
Computer TV/vga socket
Hope someone can help.
If it will handle 800x600p properly, then it should do 720x576p.
There's only one way to find out.
Usually devices like these save convergence settings dependant on scan rate and resolution. 800x600 @ 60Hz is no where near the same as 720 X 576@50Hz....and that's the problem. If the thing hasn;t been set up with geometry and convergence for this res it wont work.....Other thing is that it's extremely unlikely it'll be able to resolve 800 x 600 anyway. Sure it may accept such a signal but you ar every likely to be overlapping scan lines causing a serious softening of the image....
Gordon: I guess spending £1k on a Quadscan HD would be overkill?
I now understand why my computeur only displays a very small image in the middle of the screen, it only de-interlaces (as an iscan would).
If I understand well, the signal needs to be de-interlaced and rescaled as a quadscan (?) should do. But, what a price.
Thanks to all, for the infos.
