Also, are the recommended video settings for the replacemnt OB the same as the settings for the original equipment? As he old bulb was getting old I was watching on vivid mode, but now, it's too bright on vivid. I now can go back to Pro settings. I would appreciate any help with the recommended setting for the replacement OB?
My first OB replacement wasn't great when installed and got worse quickly. I had my second OB replacement around 6 months later. My second is now over 1.5 yrs old. It currently has some very minor green and red areas (slightly visible only on a light gray screen (e.g., memory card screen)); but it's still much better than the original or first replacement the day it was installed. I definitely would not replace this OB unless it gets significantly worse.
There really are not "recommended settings" that are valid for all sets, OB's, or bulbs. If there was one valid group of settings, they would be the "default" from the factory. My settings have differed with each OB; and even change as the lamps age. At a minimum, I would recommend getting a copy of Avia or DVE (HD version is you have Blu Ray or a currently obsolete HD DVD player). Learn to use the disc for adjusting "user settings" (contrast, brightness, color, tint, and sharpness). Then learn to use the white balance settings to at least adjust your grayscale "by eye". The grayscale ramps available on either DVE or Avia are useful for this.
