Re: DM16x16 EDID with HDR

 

¿ªÔÆÌåÓý

Hi Chris,

?

just some random thoughts:

  • Which output are you using on the Altitude? If it?s an older unit, only output 2 is capable of the full range.
  • The Altitude can be pretty picky about EDID changes. Always do a ¡°refresh EDID¡± on the device or do a power cycle
  • If I remember correctly, the DM-stuff has some compression going on for HDR content. For home cinema applications, we always try to avoid signal distribution and go for a direct connection.
  • You don?t mention a video processor in the chain, so it sounds as if you want to send an unprocessed HDR image to the projector and let the projector do the tonemapping. That?s a terrible idea since the 715ES does a horrible job on its own with HDR material. You might want to consider adding a video processor like the madVR Envy (our choice) or a Lumagen into the chain. That would provide excellent tonemapping and also solve the issue of not sending HDR over to the projector since both are sending only an SDR signal out to the projector.

?

If I find the time, I could probably do some testing as I have an Altitude 32 and a MD8x8 matrix here in the room next door.

Cheers,

Thorsten

Betreff: [crestron] DM16x16 EDID with HDR

?

Hi All,

Does anyone know what the secret handshake is to enable HDR within an EDID for DM chassis'???? Our setup is a Sony 715ES and a Trinnov Altitude16.

Everything we do will either get Atmos and no HDR, or HDR and no Atmos...? ?I know that they don't have anything to do with each other, BTW...

I have an EDID that I've Pulled from the projector. This provides 4K/HDR but no hi-res audio

I have an EDID that I've pulled from the Trinnov. This provides Hi-res audio, but no 4K? (It's set up as audio only on its own DM output)

?

Using the EDID Tool in ToolBox, I start with The Trinnov file, save as a new file, then Update the video resolutions to match what the projector file has.

The only difference is the projector file has 'Custom' VESA Block Preferred and Second Detailed Timing descriptors, which are not found in the modify lists.

These are 1920 and 1280 resolutions so I'm assuming that it doesn't really matter.... Everything else is the same.

?

The bottom line is that when the new EDID file with duplicated resolutions is loaded, I still don't get HDR!!!

$ 40K of equipment that is not performing correctly... Digital Giveth, Digital Taketh

?

Anyone have any ideas???

TIA!
