As I wrote last week, I spent some time with this years VT30 that is released in the EU/US regions.
My impressions on the VT30.
The 55VT30 was slightly better in black levels than the 42VT30. The colour accuracy of both was excellent post calibration and it has a 3D CMS for the primary colours, a 10 point greyscale, 10 point gamma.
Post calibration gamma and greyscale was definately a step up from the VT20 series. Greyscale tracks much better (so in essence the whites are more accurate). Colour was similar to last years sets but with the full 3D CMS its slightly easier to hit better results.
Blacks....I believe the VT20 might hv a bery slight edge here. The VT20s were about 0.003-0.004ft/L. Visually the VT30 either look the same or very slightly above (might be the same as I did not take my Klein K-10 for actual measurement).
The 50Hz bug is still there but very very much reduced this year. Very difficult to catch actually. IR is much improved and I did not really see much at all compared to the VT20 that had a quite a bit of IR.
Now during test patterns I found it hard to see floating brightness or floating blacks. However, I did catch that there was flicker which seems the same as the VT20.
Thanks for the heads-up anfieldude.
