Solved My monitor showing wrong colours-also a TV

Specs: windowsxpsp3, 3.2/2gb
Hi i use a Samsung TV as a vga monitor and for some reason the colour is horrid. I can hardly see much. I tried to adjust brightness and contrast with the remote and really its not any different. Also there are presets and not much difference there either. I used this tv/monitor with my other computer prior that has linux on it and there wasnt this issue. I noticed straight away the monitor and windows machine dont like each eother or something. I captured this picture with my mobile phone so not sure if it show something that someone might see and have advice for me on http://i273.photobucket.com/albums/...
. Oh and i do switch it to tv mode as well and that works well. I am using a hdmi cable for that.
The tv is a Samsung LA422a450c1xxy LCD tv.

It looks as if green is missing (red and blue being the remaining colors). Check all your cables and connections. I'm assuming it is OK when using the computer alone.

Always pop back and let us know the outcome - thanks

Try re-installing the Graphics drivers and also set the resolution to the native resolution of the TV.

✔ Best Answer
Have you tried using a different VGA cord to connect the computer and the screen? It could be you have a bad cable, and that you are experiencing signal loss.

Definitely try reinstalling any software that came with your graphics card like OtheHill suggested. You might consider looking on the manufacturers website for an even newer version of the drivers.

If it works with both HDMI on that comp and with another computer, it most likely is the cord, unless the HDMI is to a separate graphics card than the VGA. Could you try connecting your other computer using the VGA that currently connects your first? If you get bad picture with both while using the same cord, then that is definitely your problem.

Hi Rap,

you have not advised the make, full model number, desktop/laptop of your computer.

If a desktop, have you tried connecting it to a standard monitor?

Good Luck - Keep us posted.

No it looks good when using it as a tv ..looks bad like in the photo when using as a computer monitor. Used same cables before so i dont think it is them. I did replug them though if thats what you mean. Yeah i dont know what colour is missing. Its so hard to see anything well that my brain cant see the problem

I use hdmi with the tv(set top box) and vga with the computer.
My other computer worked with the vga cable and the monitor in question with no issue for a year maybe. Ah i see test with that cable ok thanks.

OK the computer is a Shuttle xpc barebone SB75G2 and the card is a Connect 3d pn 109 A035gn-10a . I dont remember the card being this model as its been a while so have to look it up. I dont have another monitor to test with ...the other monitor is the one that i am using with the linux box is also a tv as well.

Glad to hear it. Not surprised, from my TV repair days the symptoms were a classic loss of the green signal. Drivers don't suddenly lose one color. Thanks for letting us know.

Always pop back and let us know the outcome - thanks

Hi Rap, have you tried using again the old cable to see if it works?

Sometimes disconnecting/reconnecting plugs/sockets/pcb's etc. a few times will clean a dodgy contact - of which often there are many.

This method has cured many a fault.

Good Luck - Keep us posted.
