Video Card Displays Blue Hue
hi there
I was playing yesterday night on the xbox 360 which is connected to my monitor with the help of VGA. After playing I connected my monitor back to the PC and the screen shows me a blue hue display as I selected cool on the color option settings for my monitor.
I checked whether I have damaged the monitor cable or disturbed monitor port due to connecting cables, so I tried a different cable with a different DVI -VGA adaptor and I recieved same response;but my monitor on different PC was fine.
I also tried the second DVI port on my Radeon HD4850 and it was working normally.
I don't know where i am getting wrong.........
Please suggest me some views

The "cool" setting usually puts out a bluish hue. Put on the "warm" setting if there is one. I remember my old CRT had options of 6300K (warm) and 9300K (cool) of which the lower was more reddish/yellowish. The settings are actually contradictory because they are based on the colour temperature scale (in Kelvin K) where lower is actually cooler and higher is warmer. This is actually the opposite of what we feel are cool or warm colours.

A quick and definitive test for this issue is to connect an external monitor; if the output is normal, you probably have a failing LCD. The Pismo does have a history of a failing fluorescent backlight which gives a reddish/pinkish hue as it weakens...this does not sound like your problem.
I would also start up to a CD to bypass the internal HD's software and see how the display looks.
A reset of the PRAM would also be a worthwhile procedure.
Re: Video Card Displays Blue Hue
The pinkish/reddish color is usually caused by a failing fluorescent backlight. But also in the equation is the inverter that powers the backlight and I believe it will just cause a dim display. However, if the display is new, then the inverter may be the problem.
The inverter converts low-voltage DC to high-voltage AC to power the fluorescent backlight. These inverters are inexpensive and easy to replace. If your previous display appeared to have normal brightness, then the backlight is probably at fault.
It sounds as though you bought a used display. This problem usually begins to manifest itself with a pinkish/reddish cast in the lower left corner of the LCD and which disappears as the display warms up. However, over time it will progressively get worse and you will eventually end up with a display that remains totally pink and quite unattractive.
If interested, this is how you replace the inverter:
You should be able to lift out the clutch cover after removing the keyboard and heat shield. Here is a picture of the inverter:

If you hooked your monitor up to another computer and had the same problems then it sounds like your monitor might be going bad.
Check your warranty. Maybe the warranty has not expired yet

XV thinks that my XV_HUE values should be from 0 to 360, and the slider
bars in my media players were all set to the mid range, which apparently
is now setting my XV_HUE to 180. It would seem that the actual middle
value of XV_HUE should be 0 and I suspect that the min value is a
negitave number of some kind. I'm guessing that this is a resurface of
some bugs I read about from 2004ish and mostly seemed to effect NVidia
cards. Using the test button in gstreamer-properties with Xv/auto
selected worked after I had used the xvattr command to set it to zero,
but the "default" settings in my media players no longer select proper
values, and depending on the media player app, they seem to decide to
apply those settings based on different events, but my previous
assertation that using xvattr to "undo" what gxine had done fixed the
problem was incorrect.
