I doubt there's much difference between the UHD35 and TK700STi in contrast or HDR, except that the TK700STi probably has a wider colour gamut and would be perferable for more cinema oriented content. Here's a UHD35 review:Hi,
I am trying to find some comparisons of these two projectors.
They are both good for gaming although I'm curious how they fare in regards to HDR, contrast, colors? And fan noise too.
I've seen people complaining about contrast in the UHD35 but not so much with the TK700STi although it could have been their room setup.
Thanks for any help in advance!
