I'm setting up a new theatre room with an hd146x projector. I'm very impressed with it in most respects. The issue I'm struggling with is an apparent judder, stutter, judder or whatever you call it when the camera pans. Color is very good, it handles action scenes well. But when the camera pans it seems to struggle to render detail smoothly. The video and audio stay in time, it isn't lag really. I haven't seen this issue from Blu Ray, only from streaming. I've tried several sources including Roku 4K stick and Roku 4K express and even streaming from the Blu Ray player with the same results. The same scene (intro scene of 6 underground when camera pans across the cathedral)streams beautifully on nearby TVs with no such artifacts. Am I expecting too much from this budget projector? Do I need to buck up to a better projector? Better video processing? I'm really hating this. Since so much of what we watch these days is streamed, it may be a deal breaker. Any help, advice, further reading tips would be appreciated.

Yeah, this is a bottom of the line projector. There are a number of factors of actual importance in how an image looks, and image processing is a big one.

Since it is a 1080p projector, it's important to ensure you sources are all setup to deliver quality 1080p material, but at the end of the day, the projector needs to faithfully reproduce that material, and if there are problems with it, then the projector needs to do a reasonable job of making it look as good as possible. This is something that cheaper projectors just aren't typically all that good at.

Now, if the issue exists with the source, or some other part of the chain, I couldn't tell you with 100% certainty. It is important to try running the source straight to the projector, just in case there is something else along the way which may be causing the problem.

It's also something of a quirk that you say this issue doesn't occur with Blu-ray Disc, which is a incredibly high quality source, but does occur with streaming, which is a comparably low quality source.

Not sure what TVs are in use, if they use creative frame interpolation or not, or what other factors may be involved. But, yes, image processing is a key factor.

The top factors in projection image quality:
Contrast
Color Accuracy
Shadow Detail
Image Processing

It seems I've allowed a bunch of hyped up reviews to set my expectations too high for this projector. It is decent. Things fall apart fast though when it comes to panning across the screen.

I had the same concerns regarding source and all things in the path. I have gone so far as to eliminate my avr and cabling and plug streaming devices directly into the projector with no change. I think I'll be returning the Optoma and stepping up a bit to a better projector. Question is: where to look for a serious step up in performance from here? Primary focus is something that will handle camera panning more smoothly. Any suggestions?
