Title: Help, my screen is too green.
Post by: Jack Burton on April 28, 2007, 07:46:07 pm

I just picked up a Mitsubishi Diamondscan 20m and a Viewsonic 21ps.  Both are great monitors and display great, but when I connect Component video from my ps2 to the BNC ports on the back the screen is tinted very green.  The other colors are showing, but it seems that everything has extra green in it.  This does not occur when I connect a pc.  Has anyone here experienced this phenomena?

Your monitor is currently set to read RGB colour space, i.e. it's expecting a standard video signal from a PC. Since you're using component, you need to change the colour space setting on your monitor to Y'PbPr. I don't know if your monitor even has this setting, but if it does, this is the solution to your problem.

ok, I don't think that my monitor has the ability to change this setting.

Is there any kind of converter to change RGB to Y'PbPr?

Yes, in a sense. Not so much a converter though as very expensive transcoder.

Still, the monitor has component inputs, to it must be able to read Y'PbPr signals. Have you checked out the manual that came with it completely and all OSD menus?

Actually, it does not have component inputs.

What I have done is I ha bought BNC to Phono input adapters from radio shack and fit them onto each BNC input on the back of the monitor.  Then I connected the Component cable to the phono inputs.

This monitor does not have any kind of on-screen display I can access as far as I
know.

With my PS3 I can choose to output RGB from the AV multi adapter and color shows up fine.

However, I have set my PS2 to output RGB instead of Ypbpr signal and the screen just goes blank.  I do not understand why.

The PS3's colour capabilities are more advanced than the PS2's. It's hard to say where exactly the fault is in this case, but it sounds like the PS2 is expecting the monitor to do some sort of colour detection, and it's not, whereas the PS3 is doing it right in hardware, so the monitor runs it just fine. Is the PS2 hooked up to the monitor through this AV multi adapter, or just the PS3?

Needless to say, this doesn't sound like something that can be corrected for this monitor.
