I left the PJ in 'reference' mode.
- According to my meter, the most accurate color temp is actually D55 (not D65 like reviews say).
- Also, gamma was pretty far off with the "gamma correction" turned off (it was too high, closer to 2). I turned on gamma correction and setting it to 2.4 gave a measured result close to 2.2
- The default contrast setting of 90 was clipping everything above 234. I dropped it down to 81, and things looked better
- I'm not sure what Iris Limited is doing, but it's not working as described. I set brightness on a white pattern to around 17 ftL (manual iris is around 15 or so). When I switch to iris limited, the screen gets brighter, and my peak white is a hair over 20 ftL. At any rate, I decided to leave it on Auto Limited for now, as 20 ftL seems like a reasonable brightness for viewing in a dark room. The PJ can get very bright on full power, but my screen is only 90" and the throw distance is maybe 12'
Anyone else have a similar experience as far as calibrating goes? What are you guys using for Reality Creation? I dropped the resolution setting down to 10, but even then, on-screen text has some artifacts around it. In fact, any setting seems to artifact a bit. Turning it totally off does seem more blurry.
Here's a quick shot from my phone...
So at first I noticed a similar issue with D65 and my Grey Screen. I tried D55 and it was more accurate, but even after calibrating it always had a significant reddish hue to the blacks. I ended up going back to the D65 setting after I got my i1Display Pro (replacing my Spyder4), and just cranked the gain sliders around, and I'll be damned if the tint isn't gone from the black side.
However, I do still notice some pretty significant color casting in the attached focus pattern though. The same focus pattern is perfectly greyscale on my 1440p IPS, and has a tiny yellow tinge in my 1080p 39" LCD, but in the PJ it's got noticable color cast all over the fine focus patterns. Is there a way to fix this?
Brightness wise I didn't touch the contrast or brightness settings, and I'm actually using Auto Full with the bulb on Full currently. At about 50 hrs bulb usage, waiting for 100 before leaving Eco\Low on all the time. However, I'll admit I really like how plasma\popping the high brightness looks, especially once calibrated. With the grey screen lowering the brightness a bunch really loses some dynamics on the screen.
So... for RC... I actually am leaving it OFF completely now. As part of my convergence adjustments, I noticed how badly text had some blurry edges around it when you got really close. I finally realized it was from the Reality Creation mode (even at MIN!), but whenever I would turn off RC the focus would drastically get worse.
I then realized I never actually focused the PJ with RC turned off... so I tried focusing it with RC off and suddenly it was only a minor difference between RC (min) and RC (off).
I'm now leaving it off completely. While the sharpening filter does make things look a little more HD, it also:
- brings out visual noise on anything with ANY amount of compression artifacts
- disturbs the focus of scenes without consistent focus across the shot (e.g. shots using wide aperture where you have some depth of field blur, the RC filter artificially sharpens areas that SHOULD be out of focus)
- enhances lines on everything, making things like 'gradient patterns' stick out really strongly
I think I might use it when playing some HD video content (e.g. like a Blu-Ray source), but with anything else I just don't like it (especially when reading text \ web browsing).
