thanks to Joe, I went pixel peeping after owning the RS40 for almost a month. I found some convergence issues with the RS40 that were not consistent across the screen. It wasn't anywhere near as bad as Joe's photo, but off enough to show fringing on text on the left hand side of the screen.
My local dealer had an RS50 in stock, so I asked him to send it over. I spent 5 hours last night comparing the RS40 and this RS50. Both these are batch 1 projectors, shipped from the same warehouse on the same date.
on the RS50 is quite a bit better than the 40. The horizontal blue was off by nearly a whole pixel, but very consistent across the screen. An adjust to 2 put it nearly dead on. Red might be out by a 1/4 pixel or so, but not as objectionable as the RS40 was. Obviously this is complete LUCK to know if you'll get a copy that is decent or off a bit. This reminds me of high end camera lens. No 2 are the same. Many suffer with back focus issues, etc. you have to sample them to cherry pick a winner.* Focus
- Huge difference between these 2 different projectors. I tried my best on the 40 to get an even focus, but something wasn't right. If I focused in the center, both sides were off. But in opposite directions. So if I focuses the left side, the center was soft, the right side very soft & vice-versa. With the RS50, the focus is dead on across the screen. I was very happy to see this. There are obviously variances between the projectors. More pot luck comes into play here.* 3D Gamma
- YES!! I don't know exactly what's happening, but the Shadow detail in Gamma (A) on the RS50 is noticeably better than Gamma (A) on the RS40. The scene I like to check is Avatar when he gets lost in the woods (the evil night dogs scene). Gamma (A) combined with the Brightness/Darknesss Settings is exactly what I was looking for in the 40. These are direct, out of the box settings. I went back and forth 2 times to verify. This is just my subjective opinion of course, but I do have 2 low hour projectors side by side to make sure I am seeing this correctly.* Sharpness
- The RS50 is noticeably sharper, but this is likely because something was wrong with the lens in the RS40. This is especially noticeable in 3D mode, it feels like I could cut my finger on Gru's nose in Despicable Me.* Ghosting
- This has to be more sample variance, but the 'warm up' time is much less on this particular 50 than the 40. After a few hours of both projectors cooking, I tested 'Space Station 3D', the shuttle / ISS part where it's flying over the earth. Ghost city territory. This 50 is showing quite a bit less ghosting than the 40, but I cannot explain why this is happening between these two projectors, but this now leads me to believe there are some variances that can affect the level of ghosting.
I guess ignorance is bliss, I would have likely just kept the 40 and been happy with the results. By pure chance, this 50 is better in all items mentioned above, some very noticeable in direct A/B comparison.
I have the 40 for another day or so to do some more comparison. I have a ton of photos I took of all the convergence shots between the 40 and 50 on my Nikon D90 with a macro lens. once I get it sorted out, I will post so others can see the differences.
Am I still allowed to post in this thread?
