Could it be red has been decreased at some point to counter a red performance issue in the CRT. Then when you use the LCD the red is then out of balance.Ati Graphics cards have a control program called Catalyst that has colour options and Nvidia have a similar program. In their advanced options are colour control settings.
It won't be a screen issue or the cable if new so it has to be an abnormal display signal from the pc.Do you know which Graphics card is installed ?

Also look under the advanced tab and see if there are any colour management options.
