Good to have both options i spose .. Keep in mind that the HDMI standard is 102pS for jitter. The 4000 series is 80pS, the 5000 series is 45pS on the 18GHz output. The main competitor has been measured at 5-10 times higher & outside the spec (unfortunately this happens a lot in HDMI). This is on the video side @ 18GHz. The reason why people are getting better video results on many shootouts is that the projector brands Sony & JVC are using analog in the video chain & a reduction in jitter/noise makes a significant difference to perceived sharpness. Tony O’Brien reported this and was shouted down. There is a simple technical reason why & jitter/noise is it. On the audio side, the Lumagen 5000 series has been measured at 10pS!!! That’s insanely low. While you should get lower jitter on an audio output that’s running lower video res, it’s unlikely it will get that low. It’s why some people spend big dollars on a bluray player. I’d rather put that money into Lumagen, with all of the benefits. 1 Link to comment Share on other sites More sharing options...
xPLAYRZx Posted June 20, 2023 Share Posted June 20, 2023 New beta firmware is now available - http://www.lumagen.com/docs/radiance_pro060623.zip Beta 060623- Posted 061923 Significant improvements to HDR dynamic tone mapping. With these improvements, it's recommended to set dynamic pad (DPad) to 1 and setting DeSat to On to take full advantage of the improvements. These HDR settings are available either by pressing left arrow on the Lumagen remote or in the menu under Input: Options: HDR Setup 1 Link to comment Share on other sites More sharing options...

xPLAYRZx Posted June 20, 2023 Share Posted June 20, 2023 Just finished installing... will take it for a test drive tonight. Very good reports thus far. 2 Link to comment Share on other sites More sharing options...
wooferocau Posted June 22, 2023 Share Posted June 22, 2023 As always..... Jim and team continuing to provide terrific updates and improvements... That's the beauty of the "FPGA" based architecture of the Lumagen... It can be updated and improved without the need for "Hardware " changes.. 3 Link to comment Share on other sites More sharing options...

xPLAYRZx Posted June 23, 2023 Share Posted June 23, 2023 Initial impression of the latest firmware are good, although I was already getting a great image with the Lumagen. HDR images are a little brighter in this release, and the picture seems a bit cleaner... maybe? I just had my projector replaced and calibrated so a few too many changes to confidently attribute them all to the latest firmware. Apparently significant work has gone into improving de-saturation which should help challenging HDR scenes. I'll need to get through some more content to experience this for myself. Overall though, it seems to be another improvement to a great product, I wouldn't hesitate to update your firmware to this beta release. Link to comment Share on other sites More sharing options...
wooferocau Posted October 20, 2023 Share Posted October 20, 2023 Lumagen owners/users... Do your self a favour and install this build.. http://www.lumagen.com/docs/radiance_pro100223.zip The Radiance Pro keeps getting better and better.... Thanks to Jim and Pat for their ongoing dedication to a fantastic product!! 2 Link to comment Share on other sites More sharing options...
xPLAYRZx Posted October 20, 2023 Share Posted October 20, 2023 Installed 100223 last night, looks excellent Although, I thought the previous FW (Beta 082623) was an excellent revision. DTM has really come a long way on the Lumagen over the past 6-12 months. 1 Link to comment Share on other sites More sharing options...
