no green channel

#1
when I connect my 42" plasma tv to my dual-vga g-force 5500 I don't get any green. only red and blue channels.
everything seems to be set ok and the other monitor displays all colors.
the cable when connected to another monitor works fine.
windows recognizes the tv correctly.

any ideas?

It sounds like the connector on the back of the plasma screen is dodgy. Have you got another source you could try showing on the plasma screen on the same connector?

Also, how are you connecting your plasma screen? Is it a vga connection or TV out or a vga to dvi adapter or something else?

If you're using an adapter it could be the adapter that's faulty.

I'm using a 15 pin d-sub cable with a gender changer. Later today I'll try hooking up a laptop to it and see if it looks the same.

ok
I connected another computer to the TV and there's still no green.

This may or may not be a dumb question, but is a 15-pin D-Sub RGB connector different from a 15-pin D-Sub VGA connector and are either of those different from a HD15 connector?

The only part I haven't been able to test is the gender changer. When I bought the 30' cable I just glanced at the back of the tv and saw pins so I figured that end would need to be female, but I looked at the rs232 instead of the RGB connector. That's why I needed the gender changer.

"15-pin D-Sub RGB connector different from a 15-pin D-Sub VGA "

General Rule:
If the names are different the parts are different. Google both and look for the wireing diagrams. You can mod your's yourself or buy the right kind.

WTF I'm feeling benevolent in spite of Perris's stupid oil post....

Possible you have a mac converter? They wire differently.

I've been googling and asking jeeves.
From what I've been reading it seems like I'm doing everything correct. I can play games and stuff fine....there's just no green at all. When I go into the color correction, the red and blue are red and blue, but the green is black.
It just seems like I'm missing something simple somewhere. I probably just need a checkmark in a box somewhere I'm missing.....that would be an easy answer :laugh:

WOO!!
Problem solved!!
Something is wrong with the gender changer. A friend brought over a monitor cable, connected it, and everything worked fine. Now I either need to get a new gender changer or buy a new 30' cable with the right ends. I'll prolly try the cheap option first

Thanks for your help guys!
