It does cut glare (compared to my GB12) but no real feel on the pen to me - but I am NOT an artist.
Have you had a chance to test for low-end black crush?
@dstrauss could you take a quick look at Lagom's black level page and tell me which is the lowest visible square at 25%/50%/75%/100% brightness (maybe do a quick comparison to your GB12 too)?
One of the nice things about the Z Canvas is how nicely-calibrated the gamma curve is: even at 25% brightness, square 1 is still distinctly visible.
@desertlap have you noticed any vertical banding on a 5% gray window? How consistent is the whitepoint color temperature to D65, at various brightnesses?
Any other other artifacts you guys noticed, like red ghosted trails when scrolling text quickly (which appeared on some earlier Samsung OLEDs)?
If Samsung's latest panel has solved all these old problems, this really could be the prize tablet of 2019.
Still testing with the updated driver and firmware.
Tentatively though, once calibrated the gamma curve is at least as good as the Z canvas and with the fixed driver the white point color temperature only varies 1 or 2% across 90% of the brightness range ands only starts to vary a measurable amount at the extremes...<~9% or >90% settings.
No red ghosted trails yet observed either, but we hadn't really looked for those but will now.
The one negative about the display and I can already say is that out of the box the calibration is mediocre and you need to take the time to calibrate it to get the best results. And we did communicate that back to HP.
OK - never have done this before, so take with a grain (or pound) of salt and adjust for old eyes, but here's what I see (table attached). GB12 is clearly better if looking for lightest squares visible.
Would you mind fast-forwarding about 3 weeks and tell us how you will like it then?
"No," you don't mind?
Yes, I do mind - no means "no Carnac for you!"
Those results are due to out of the box the gamma being too high. Out of the box the unit we tested was 2.2, we got much better results with 1.8
