I have an RS1000/NX5 (115" screen/1.2gain at almost min throw) so I'm ~50ftL in high lamp give or take. With the dtm from MadVR I ended up leaving it on low lamp except when I'm watching 3D. I noticed a slight increase in brightness, but ended up deciding it wasn't worth the lamp wear. I have the projector tucked away in a closet with a port hole so noise isn't an issue. The tone mapping by MadVR is so good I just didn't think it was worth going to high lamp. I'd set it up how you want, calibrate, etc and then just flip back and forth and see how you like it. I run mine right now low lamp 0 iris and no DI. For SDR I ended up doing low lamp, -10, and auto 2(the yellowing isn't noticeable for me below -8 or so).Been using madvr with my x970R for a while, and now have an NX9 and a DCR lens coming for it.
I estimate I should have up to ~44ftL available for HDR from my 1.18 actual gain screen. I only had about 25ftL available from my x970R with 1800 hrs on the bulb.
With this additional brightness, I'm wondering if I should be doing something else in how I output from madvr?
Currently tone mapping HDR but outputting SDR to the projector. Should this change now with the increased brightness?
Also, is the proper way to determine the nits value to put in the newest version of madvr to read ftL on 100IRE pattern off screen when in HDR mode/high lamp using Mascior's HDR patterns, and then convert to nits?
Finally, about madmeasureHDR given my details above - what would be the recommended settings to generate that measure file for my setup?
