The technology on all of these E-shift DLP's is the same technology and all of them have very limited native contrast near 1,000:1. When compared side by side with a high contrast projector, that glaring weakness really stands out, when you look at darker scenes. As for you bringing up the 4500 having laser dimming, the 4500 starts off with a native that is 5 to 10 times greater than these DLP's. If the 4500 only had around 1,000:1 native, I would have a problem recommending it also. If you are going to debate this, debate the subject, not attack the poster. Not doing so will get your posts deleted.
No one is arguing with you about the benefits that DV brings to the table. I'm just apprehensive about how it looks through this specific projector....
...You can go on and on about how you have it setup and how I haven't personally seen your new settings, but I've seen enough projectors to know how the image will look, roughly speaking, given the objective performance the LK990 offers. And while I didn't plug your new settings into the LK990 when I had the opportunity to play with one, I can guarantee you that no amount of fiddling with settings is going to make enough of a difference to totally transform how this projector looks. To put it simply, you cannot fix the atrocious contrast performance with the setting options in the menu.In the year 2020, against other projectors around its price, the LK990 falls behind dramatically in terms of dynamic range. So, again, you can play around with the image between black and white all you want, but the level of black the LK990 offers is not even remotely competitive and this limits how this projector can compete. Before you go on about how I don't understand what you're doing, trust me, I do. I've played around with straight HDR going into projectors quite a bit....
....Dave, what if we were to send DV to a Sony or JVC projector and find a comparable set of image settings that you've applied to the LK990? Why not do this instead so you can get the native 4K image and higher contrast that these other projectors offer on top of DV? Why waste time with the LK990?
...While I agree, you can't really have high dynamic range without one or both of the ends being higher and/or lower, in this case....brightness, along with maintaining some semblance of a good black floor, which this has with these settings and features engaged. You may have a display/projector that can do awesome black which is great for the low end of the scale when figuring dynamic range, but you also need to at least have the higher end available too if you want TRUE "High Dynamic Range". All you have to do is think of the audio world to know that. If your projector tops out at 100 nits or so, you don't have that, period. Sure, your video image may use dynamic tone mapping (compression is all), but all it is doing is showing a 100 nit sliding range of what the frame is that's being displayed, so if it's a dark scene with a bright light in it as I mentioned earlier, your sunlight/specular highlight will never be even close to where it actually should be, since it will never get above 100 nits, if that, based on your compression (tone mapping) algorithm. I am getting the full 100 nits image WITHOUT compression, and then using the nits above that (~175 nits range) for anything beyond the basic HDR movie image, i.e. - explosions, sunlight, flames, chrome flashes, lens flares, specular highlights, etc. This is exactly why HDR/DV Flat Panels with higher brightness capability look so much better than projectors, even the worse black level ones like LCD, which everyone should agree....
Kris Deering really dialed back the brightness on my RS4500, but improved the shadow detail and darker scenes substantially. Even guests remarked how it looked much better. Of course the Lumagen's dynamic tone mapping helps substantially. At least on my screen, I don't need the shear brightness anymore.
BenQ LK990 First ImpressionsJust took possession of a Lumagen Radiance Pro 4446+. Really looking forward to checking out its scaling and DTM capabilities.
Dylan,Do you run madVR ?If so , will be interesting to hear your thoughts on the 2 solutions.I have a 4242 Radiance that i use to compare to madVR..
