JVC DLA-RS60 - Performance

Posted on October 10, 2013 by Art Feierman

JVC DLA-RS60 Measured Brightness

None of the modes provides anything resembling the JVC DLA-RS60's claimed 1300 lumens. After contacting JVC it was decided that I send it in to be checked out.

In the meantime, I've been hearing from a few readers who have purchased units (RS50, RS60, X7 or X9s) and they are reporting similar numbers, or a bit higher than ours measures.

As it turns out, there's been a lot of buzz about this on the net.

There is another mode. Or rather it just requires turning off the color profiles. This gives a dramatic boost in lumens getting the projector up to 1000 lumens or more, which is now sounding more reasonable.

Lumen Output and Color Temp at 100 IRE (mid zoom)

Film 351 @ 6024
Cinema 383 @ 6725
Animation 506 @ 8531
Natural 500 @ 6829
Stage 500 @ 7955
3D 507 @ 8997
THX 497 @ 6828
User 1 or 2 500 @ 6820

There is a problem however, or rather so I am being told by an otherwise generally happy owner (I think), with running with the color profile off, and that is that the color is really pretty poor. The color temp is apparently around 9000K, One person indicated it's probably worse than any projector he's seen's dynamic mode.

He also pointed out, though that while it looked really bad for 2D viewing it wasn't too bad for 3D viewing. Again, I learned about this from readers, and visiting the forums. I can't verify the numbers. We will update all this when we get another projector from JVC.

Another thing about the brightness to note is that this year JVC quotes their 1300 lumens at 8500K. With previous generations they quoted D65 - 6500K. That had a lot of us expecting a dramatic increase in brightness. Well it looks like there's a native mode - that gets up in the 1000 range, but, anything that looks good, is still down around 600 lumens or below. By comparison, the Sony VPL-VW90ES managed 750 lumens in a brightest mode that still had very good color.

The Effect of low lamp (eco) mode on brightness

Lumen output drops about 35% (measured: 34.5%), which is significantly more drop than most projectors. Typical is 20-25%
