Are there other, less expensive, no-color-wheel DLP projectors and, if so, what are they?
RBE is caused by when the color components don't cycle fast enough to trick your brain into thinking they are a full color frame
It is similar to like when your framerate is too low on a moving picture and you see it "stutter" instead of motion. As you know, once you get to a certain point your brain stops seeing individual frames and starts seeing motion.
The same applies to RBE, and the slower the colors cycle the more potential there is to see it. Via the electronic cycling method, the colors cycle around 3x faster than the fastest color wheel. Sort of like reducing the chance of seeing stuttering in motion when going from 20fps to 60fps, you also reduce RBE potential in a similar fashion.
Now just like those gamers that say 120fps is much smoother than 60fps, there are going to be the rare folks that still might notice RBE with a projector like the HT9060. But for the vast majority the cycling will be so fast that RBE will not be visible, and hence this is the best compromise of sharpness, rbe , and affordability.
In the 4k world there is not really any other projector that is both cheaper and also good as the ht9060 with no color wheel, though it can be gotten as a steal from benq direct refurbs when they have stock. This model had a prior model that was released half baked with incomplete firmware that even today is missing key features (didn't even have fast cycling enabled at launch) , and that model is therefore a bust.
In the 1080p world there are several very good - but now also out of production - projectors that have similar fast cycling tech but they aren't bright enough for HDR; examples like the Runco q750i, DPI Cine LED 1000, and Vivitek H9090. But these aren't great for modern 4k as they aren't bright enough since they don't use the hld tech.
They are working on a version of HLD LED for the smaller 4k 0.47" DMD and that should produce models available new under $3k in the near future. For now though picking up a refurbished benq ht9060 from benq direct when they get more in stock is your best bet for low cost.
