Or get a JVC DILA NX or NZ series projector. JVC’s dynamic tone mapping is the best short of dropping another $8k-15k on an external VP.

Epson and Sony don’t have the capabilities of JVC’s DTM. And Sony is garbage with its long documented SXRD degradation issues.

It's purely my very specific situation. Someday when I get a new projector I might change back, depending on how the projector handles HDR and/or if it auto switches presets.

Another option is to use Panasonic HDR to SDR conversion. I used it when I had my JVC 540.

My Sony definitely isn’t garbage, even after almost 5000 hours, and Lumagen Radiance Pros start at $5000; even lower used I got in on it for about $3000, actually.

If you want a flat and boring image

Good luck

LOL… as you said projectors struggle with HDR. The Panasonic HDR to SDR in BT2020 colorspace is not flat… as much as I expected from your response

Sony’s SXRD’s are notorious for deteriorating in a few thousand hours. A well known calibrator has seen evidence of deterioration on EVERY unit he has returned to calibrate. Some are $60k units that have deteriorated to well under 1k:1 when they started at 10k-15k:1.

I had one that went from dark inky blacks to bluish gray in about 5 years.
SXRD has been problematic from the beginning. They don’t even make commercial theatrical units anymore because theaters were upset with premature failures of the panels.

Good to know… the JVCs don’t need it unless doing a lot of AR changes.

right, that's the tone mapping I was talking about. But it wasn't playing nice with my regular settings.

Seeing as I'm using just the one display (deficient or not) to compare regular Blu-ray with UHD Blu-ray using Panny's HDR to SDR conversion, my experiences are perfectly valid.

I was unaware that JVC's DTM was considered to be this good. Their new offerings were never on the table for me though, due to price.

Considered very good. MadVR slightly better but not worth $15k price unless you need other VP capabilities. Add the JVC’s new 2.0 FW for their laser models that implement a new laser dimming there’s no reason to buy anything else in the JVC’s price range

Same calibrator that was reporting Sony issues suggested this was the best mode to use with JVC’s pre-native 4K models.

Never found it flat. Just made the picture more SDR like with no specular highlights. Got the benefits of the expanded color gamut without sacrificing brightness trying to show specular highlights. Tradeoff yes but it made a lot of too dim to view HDR titles watchable on my JVC 540.

A lot of projector manufacturers just flat out lie about HDR capabilities. Sony tried to imply they have dynamic HDR on their new line which was 100% bull$h!t.
They all look good in bright scenes but evaluate them in a low light level scene most of them are crap unless one has an external VP like the ones mentioned above.

On my 3100 laser unit I use the new Auto Wide mode frame adapt HDR setting combined with the new laser dimming mode 3 there’s not much left to improve upon wrt video. All while passing HDR10 video from the UB9000. No reason to use the Panasonic optimizer anymore.

I might have to give them a call.

Try this out. Sorry, was trying to find a place where the images will show properly. This is from the 9000 Service Manual which I have but this should also work for the 820 as well.

I will try this later tonight and report back. Thanks!
