Not interested in 3D
Is the RS45 better tan the RS25 as far as 2D?
Why?


thanks

RS25 should be better

Actually it should be a draw. The RS25 will allow better color tweaking if nothing else.

The rs25 has a little more depth due to it's slightly better blacks. The THX mode alone easily bests the rs45 in terms of accurate color and skin tones.

The RS-25 has the same Native on/off rating from JVC as the RS-45, both 50,000:1.
Some of us measured and confirmed the rS-45's Native On/Off was as stated, 50,000:1.

The RS-25 has better calibration options, but the optics may be slightly improved in the RS-45 and have a sharper image (depending on luck of draw more than anything). The RS-45 is brighter at first, but over time the RS-25's lamps may hold up better.

I think it is more what JoesYah stated, too close to pick a winner, would be more based on unit variances of the individual MFR'd unit than a projector vs. projector thing, although the RS-25 will calibrate better.

I would think pans would be smoother on the RS45. 3D has forced the use of better panels and circuits that refresh more quickly. At least reviews seem to say panning is better with each newer model.

Interesting question, and one I struggled with earlier this year when contemplating an upgrade. I agree with Coderguy - very close call and unit to unit variation probably plays more into it than anything else. The RS45 had some upgrades over the 25/35 other than 3D, but depending on how good of a unit you get, overall performance could go either way.

The RS45 is capable of higher light output and has lens memory - so if you have a big screen, or want to do 1:235 without an anamorphic lens, those are two votes for an RS45 and are upgrades independent of 3D capability. If you're a sports fan, I believe that FI on the 45 is better than what the 25 offers. At the same time, unit to unit variation means that contrast ratio, convergence and uniformity are all wild cards - and a RS25 or 35 that excels at this group of variables, could outperform an RS45 with less than steller marks in these categories.

As has been stated above, calibration wise, the RS25's built in package is superior to what's in the RS45 - you'd need an external CMS like a Lumagen, DVDO or VideoEQ to get you what the RS25 has built in.

Personally, I have a thoroughbred RS-25 (it didn't start that way - ended up like that after JVC replaced the optical block which I can only imagine was a RS35 optical block), and the upgrades for the RS45 didn't have a ton of relevance for me (little interest in 3D; modest screen size with lumens to spare so brightness not a problem; no real use for lens memories as I have a 16:9 screen; not a huge sports fan so improvements in motion/FI not a huge deal) so I opted to hold onto my RS25 for another season, versus grabbing an RS45 that might end up as a downgrade if I got a mediocre unit.

So if you have the chance to grab an RS35, or can take a look to verify that its a really good RS25, and/or value the calibration controls - and the handful of upgrades (3D, brightness, FI, lens memories) aren't critical for you - you may come out ahead that route vs rolling the dice on a RS45.

I own a JVC RS25 with 400 hours on the lamp and have an opportunity to buy a new RS45 + $ 700,00.

Do you guys think this is worth it?

Will the RS45 be the same as for 2D performance? I don t want to loose anything here.

Are the panels of the RS45 better then on my RS25? (hate the motion handling on the RS25).

I would only upgrade if you are interested in 3D, I doubt if motion is better

But since 3D on the JVC is not working properly because of the major ghosting it has this is no option right?

I wouldn't say major ghosting, maybe on video games. I have no problem with the 3D. I really enjoyed 3D on my RS40 last year and continued to enjoy it now with my RS55. Also, if you are going to watch a limited number of 3D titles, I would not base my decision on a projector that does 3D better. But if you are going to watch a lot of 3D, maybe a JVC is not what you want. Last year I bought about 40 3D titles, but after watching so much 3D, then the 2D version, I much prefer the 2D versions. I guess, if I watched more 3D than once a month, I would not have chosen the best 2D projector. I didn't want to sacrifice my 2D experience for 3D once a month.

I think the agreement we hashed out above is that 2D performance on these two units is close enough that unit to unit variation will play more into any differences than anything else.

If improved motion is something that is really important to you, it sounds like you may want to take a look at what Sony has to offer.

I can only go for this offer (trade JVC for JVC).

Would I need to buy an emitter and glasses or do they come with the JVC?

Nope emitter is about $75 and the JVC glasses is about $150, but you can get some Xpands for $70. Not cheap

I'm not sure what AVS is currently charging for the 45, but my guess is is that you'd probably come out on top with that deal compared to what you'd get for your RS-25 on the used market and purchasing a RS45 somewhere. Could you take a picture quality hit? Its possible. The 2D on these guys is really similar and if you have a really good RS25 (in terms of convergence, contrast and uniformity), and went to a mediocre RS45, your 2D could very well look worse.

Do you calibrate your image? The RS45's capabilities aren't as good as what's built in to your RS25. If you like to calibrate your stuff, the RS45 would need something external to get you as close as the RS25 allows you to get.

Most people I saw really evaluating upgrades this year were RS20 owners - it seems that the 25 and 35 owners were more on the sidelines - both of these guys still produce stellar images. For those not eager to jump on 3D, the decision is a little harder.
