Match Dynamic Range On
Match Frame Rate On

This then runs to my HD Fury Vertex which I cant decide between auto EDID or custom, and either passthru scaler or custom scaler? Trying for the best possible pic obviously.
Currently using harpervision settings.


Issue I'm having is when watching a movie on Itunes Movie, every 5 minutes the on screen display of the vertex shows up. This doesn't happen in Netflix, or the same movie on vudu, just itunes movie.

any chance you were able to check?

Is there a lens lock on this? When I turn the vertical/horizontal shift dials nothing happens.

SDR=standard dynamic range - standard color range and image dynamics of Blu-ray

HD=high definition - 1080p Blu-ray definition
UHD=ultra high definition - “4k”

You’re not losing picture resolution. When playing UHD content your player sends the UHD content to the projector at its original 4k resolution. However, it must convert the content’s HDR to SDR since the projector does not support HDR color range. Many people actually opt to do HDR->SDR conversion even when the projector supports HDR natively. This is because they may have a superior way of tuning the image parameters such that it ultimately shows better on their projector.

That is not what is actually being done. The image is not converted to SDR. All they are really doing is stripping the HDR flag, but still sending the HDR signal. That allows a different device like a Panasonic player to do the HDR tone mapping using a different curve, rather than the projector. The 970 does not do any more than Rec709 color space, which is what a regular BD uses, so the 970 does not really benefit from the wider color space of HDR. It may look different, you may like it, but it is not an improvement in color space size. Often times the color saturation stacks up and the color appears more vivid, due to the poor tracking.

Ok i understood some of that... Should I stick with blu rays or UHD 4k movies? I have a Sony X800 right now not the Panny 820. If i had the Panny would i go with UHD 4ks?

UHD will look better than regular BD, due to the higher resolution.

Exactly. Color will look better even with a more limited color space due to higher color resolution. Standard blu-rays use 4:2:0 subsampling, which means if you strip away the luma info and look at the chroma info only, it's effectively HALF the resolution of 1080p. Throw up a diagonal red line on a black background and it becomes more obvious. I remember the old dvd menu of Pixar's 'The Incredibles' being a torture test for subsampling limitations due to all of the stark red polygonal shapes. Upsampling of course helps with this, but it's always better to start with the best image possible. ^_^

So I got my LK970 calibrated and was wondering why he turned the sharpness all the way from 50 to 0? Is there a reason for this?

Who is he? Did you buy it pre-calibrated?

My bad.. he dropped sharpness from 7 to 0
dropped my contrast from 50 to 34
and dropped my brigthness from 50 to 44

Here is his website: https://www.integratedenver.com/

His name is Sean Hammond

He came to my house and calibrated it. It looks great but was wondering about these settings.

Sharpness controls are an artificial edge enhancement. Calibration is about reproducing the source accurately, not enhancing edges artificially to give a false impression of sharpness on content that isn't itself sharp.

You can turn it back up if you don't like it, but it should almost always be set at zero or very close to zero.

Has anyone noticed the crazy low price on these at benqdirect.com for a refurbished one? I'm tempted to go get one for that price even though I dont need one.
