No color on 5,6" TFT when connected to NVIDIA Geforce 4200

Hi!

Hope this is the correct forum for this question:

OK, i have a stationary PC which i usually (with no problem)
connect to my TV via the S-Video connector on the graphics card.
This works perfectly with colors and everything.

Now i have this 5,6" TFT screen which i also would like to connect
to the same graphics card.

This works, but i am not getting any colors on the displayed video.
The screen is also sligtly dislocated, creating a 5 mm black bar on
the left and upper corners.

Worth to mention is that the input is RCA and not S-Video, so i have
an converter in between, but i use the same converter when connecing
to my regular TV.

Below is a link to the (very very HI-TEK TFT Display

Any help would be very appreciated!!

the connection is rca?


you mean three wires?


if so then you should connect only the yellow video wire

Sounds like composite signal on (single) rca connector to me.

That sounds more like YCbCr, ie. separate chrominance (two separate wires)
and luminance (Y) using three rca connectors, somehow I get the impression
that he is using the composite output (GF 4200).

If he connects the Y to composite he will only get grayscale, this matches
his description but it is also possible to get grayscale (luma only) signal
from composite source: happens with el-cheapo receivers sometimes, then
again, using composite is stupid to begin with. That connector should
seriously die. >B)
