G1s screen type

I have a question regarding the type of screen used in the G1s. I know the identification number is LTN15P1-L03 and the monitor is a Samsung. However, I was wondering if it was a PVA panel. I’d assume so considering the excellent viewing angles and color reproduction, but the TN in the designation gave me pause. I’m quite pleased with the screen despite the slight sparkle I was finally able to notice. As mentioned in a different post it has a slight distortion of white that remains in place as windows move. I looked at a macbook pro recently and it really illustrated what I should look for in regard to sparkle. What egg heads in apple thought that much reflective coating was necessary? The G1s is very mild in comparison. I read elsewhere that dither caused sparkle, but according to Wikipedia (not always accurate) it actually causes graininess. I hardly think asus used an inferior panel and had it dithered. The colors would have been distorted, and the viewing angles would have been lousy. This, most assuredly, is not the case. The sparkle also appears above what the screen displays. Plus, the p in the numbers indicates a professional panel correct?

 

The video card also influences the display quality. Many people forget this.
