great discussion on the lumagen calibrations... keep it going.. !
a few weeks ago I mentioned wanting to directly compare the 3D performance of the Epson 5020 and BenQ W7000. I recently spent a few hours with a direct A/B setup watching various clips of my favorite 3D movies.
This is the first time I've had to chance to watch 3D with my newly blacked out room. My 142" 16:9 is very close to my ceiling (inches) and fills up an entire wall. It's remarkable how much more engaging the 3D is when there is nothing in sight around the frame to distract our attention.. this is a good and bad thing...
The bad is now PQ flaws are more obvious to my eyes. For example, I can now see the iris on the 5020. In 2D and 3D. My HP screen is bright so subtle changes in brightness are magnified times 2.8 and it becomes a bit distracting. I'll probably get used to it,but it's something I didn't really notice before the treatments.
After the change to the dark side, the RS55 is the 2D star of the show here, it looks outstanding @ -11.Epson 5020 vs BenQ W7000
Both projectors have been discussed in detail regarding 3D, so these are just a few observations.
- 3D glasses - For the Epson, I was using the factory RF glasses. I used the Optoma ZD201's for the BQ. These are 'technically' the best DLP link glasses i've used since both lens completely block out the red flash signal. This is important for maintaining perceived contrast in both eyes. The 2nd best in this regard is the TrueDepth 3D's. The BQ 2nd gen are amazingly comfortable with large lens but actually perform the worst in this regard. Too much red flash gets through the right eye which is distracting.
- Brightness - The Epson is a bit bright than the BQ. I also have 375 hours on the BQ lamp and the Epson is less than 100, so it's hard to compare them directly in this regard without new lamps. The W7000 at dead center on the HP is bright enough for me. The Epson appears 1 notch brighter in the direct A/B.
- Color - Both projectors can be calibrated behind the glasses and corrected for the tint color. Everyone who has a meter should do this. 3D is much more convincing when the color is right. Both looked very good behind the glasses, no real winner here.
- Contrast - The #'s show there is a noticeable difference between the 5020 and the BQ W7000. You can easily see this in 2D if we're watching sci-fi. It's not as obvious in 3D mode with the glasses.One of my favorite movies to use in this comparison in Step Up 3D. It was shot in native 3D, very sharp overall and has great shadow detail in the various night club 'battle' scenes. The Epson has a bit of an advantage here, but it's not as clear-cut as the #'s would have you believe. Neither are the JVC in this regard.
- Flicker - Epson is very good here. Better than the the Sony, and definitely better than the JVC. Overall a non issue for those sensitive to flicker. Those 480hz panels are doing some work here.
- Crosstalk - My room is a now a math formula for seeing crosstalk. Big Screen + 2.8 High Power material + close seating + dark room = you will see crosstalk if it's there. At least I will since I have been spoiled by the 3D DLP which cannot display crosstalk under any circumstances. The Epson 5020 is very good in this regard for a non-DLP. About on par with the HW50 with 3D frame packed content. Just like seeing the iris now with the dark room, the crosstalk on the 5020 has become a bit more obvious.
- FI in 3D - I watched a number of action scenes in the Avengers and a few other titles. The W7000 has excellent FI in low mode. It doesn't look like soap opera effect, just a very subtle smoothing of the image during fast paced scenes. The HW50 also has an excellent FI in 3D as well. IMO, This needs to be a requirement going forward. Even those who generally don't like FI in 2D are likely going to enjoy in 3D.
This was a personal comparison for me because I was considering going over the 5020 from the W7000. Mainly because of the RF glasses. We have visitors and keeping the DLP links glasses in sync with the younger folks can be a bit of a challenge. It's actually better now that my ceiling is dark, I think the room reflections were causing issues with the DLP link signal. Also, FI is now a requirement for me in 3D. I am expecting we'll see this added to the '5030' assuming they are going to follow up again next year.
My conclusion - I have been tainted by 3D DLP's crosstalk abilities. I saw this in 2010 when comparing the Acer 5360 vs the JVC RS40. How could it have been possible a $500 projector whooped on the expensive JVC? (flicker and crosstalk, obviously not contrast). I am staying with the BQ W7000 (for now) as it's a great 3D compliment to my JVC RS55.
it's interesting that 3D could have become DLP's 2nd lease on life. TI hasn't made changes in years. The mid-tier (5-10k) DLP market is pretty much gone. it's either 3K or below or 10K + now. This is a shame as I think there would be a market for an under 10K 3D DLP with a DC4 and decent brightness. Marantz and Samsung could have likely done this if they stayed in the market.
