Several months ago I purchased an X5900 (uk) and found the 3D to be pretty good, I already had Xpand X105 lite glasses along with Samsung SSG3100 so just purchased an oe jvc emitter. This works perfectly on my non retaking basic white screen but tilting my head 90 degrees I could see a very small increase in brightness so I bought a pair of the horizontal polarising jvc glasses to compare.
Interesting results, as expected there was around 5-10% brightness increase so I was initially very happy as any small increase in 3D brightness is welcome.
However I noticed right away that there is a colour temperature difference between the xpand and jvc glasses.
As a background I suffer from neck pain and my preferred position is looking straight ahead or slightly down with my eyes looking slightly up at my screen, in this position the Xpands vertical polarisation give an accurate warmer colour temp. The jvc glasses with the horizontal polarisation in this same position give a colder colour temp which is not accurate but if I tilt my head back then the warmer colour tone returns but this is uncomfortable for my neck.
So the xpand 105 X1 have warm tone when looking down and cooler tone when looking up. The jvc has the opposite, I'm quite curious why this should happen and if you DIY calibrate you need to take this into consideration when fixing the glasses over the coloromiter otherwise greyscale will not be accurate if the glasses are at a differnt angle when wearing them.
Anyone else notice this ?.
