I am not qualified to answer that question since I am not actively following JVC projectors after I got mine in early 2012.
From what I can see, the increased price tag of the X75 gets you:
- ISF / THX certifications
- Higher native contrast
- Better lens memory function
- More screen adjustment modes to suite different branded screen
Besides these they are essentially identical and I am pretty sure they have the same hardware but more aggressively tuned for the certifications and higher native contrast (hey I have been wrong many times!). Here’s my laymen impression:
ISF / THX certifications – if you calibrate projector yourself then these certifications don't mean much, but if you don’t and rely on presets, these could and should give you a more accurate picture
Higher native contrast – nice to have but unless you are looking at a very high contrast image, like a dotted checkered box, for a reasonably long duration, I am not sure how much these translate into actual benefit, high contrast scenes last usually for a split second but picky users might like to have the best.
Better lens memory function – I have it on mine, I only need one memory and I have really never use it much, but of course if you switch between movie aspect ratio and move your lens around say if you have an anamorphic lens, it could be useful
More screen adjustment modes to suite different branded screens – I suspect your Firehawk might already been included in the X55 more limited screen adjustment, if that is the case, the extra selections are redundant, but I do not have and cannot get any conclusive info online.
I also understand for the X75 there is an auto-calibration feature using built-in software and a Spyder4Pro or Spyder4Elite (optional) to run through the greyscale set up. This is nice but if you are going to get a meter you might as well get a complete calibration software package as little as USD250, and the X75 only does grayscale so how useful it is depends on how ‘picky’ you want to get.
If budget is not an issue and if you do not intend to manually calibrate your projector then X75 has its virtual, otherwise to me the X55 might be more cost effective, better bang for the buck model. Demoing projectors is a way to go but unless you are certain they are calibrated to the same standard using same method playing same material on same screen in the same environment, I would be a bit cautious. Much like visually comparing TV in Fortress, useless to a certain extent.
Hope this is somehow useful. |
