Hello,

The P version has a slightly lower energy consumption value (see the energy label)! That's the only difference we found.

There's a great comparison tool on the digitec website

I must admit I have never heard of the others (P-B & G-B). As far as I know, only the 950-B is available on the LG website. This is also the model I bought after extensive research about 3 years ago. Btw, there are now better and cheaper monitors with similar dimensions.
