Haha. I was triggered by a new projector. My HT sound is due for an upgrade as it’s 20 yrs old. Back in the day when I set it up, the Xtremeplace folk were doing BEQ with a Radioshack sound meter, a CD and a strange device called a Behringer Bass Feedback Destroyer. Might just wait for the new Denon AVRs to try Dirac. Wonder if the Pi/ezBEQ can interact with the new Denons?
Nice. Was the setup of the device difficult? To be frank, the steps on the avs forum looks a bit daunting after reading them lol
Btw, for mobile forge, I’ve came across posts in the avs forum where experienced calibrators advised that the mobile forge patterns is not accurate for external display. And its more for mobile phones though it can be done for external tv. So best to avoid this method unless we have a means to verify that the patterns are accurate for external monitor.
Once the PG is not reference/ inaccurate, everything else will be off tangent.
With Pi4 + Pgen, we will be assured that the patterns will be perfect and not the source of issues.
There are quite a lot of things to do so just follow them in order. If you get stuck, I can help. I can burn PGen onto a SD card for you, but you will still need to install the control software on the PC otherwise you won’t be able to configure things from the PC as PGen boots up on the Pi into a blank screen.
The control software is quite fiddly as they use something called Device Control to connect to the Pi running PGen. Its a piece of software from Lightillusion, a producer of color management tools for the broadcast sector. Lightillusion usually sells Device Control for GBP10, but somehow following the guide you can download it for free. The writer wrote it in a language called Perl and it must run in the Perl environment so you have to install Perl to use Device Control. When you run Device Control, it just sits there like a Server. You then have to open a browser to talk to Device Control, which then talks to the Pi running PGen. An additional complication is that Device Control needs to access templates on a Cloud server to figure out the latest way to talk to PGen. Hence, within Device Control, you have to open a user account with password so you can access the latest template for PGen 1.3, the version which does HDR without a HDFury box.
Apparently, Device Control can also talk to LG, Panasonic and Sony TVs directly, even Lumagens. That’s how the Colorspace calibration software controls those TVs for calibration. So, its a general purpose control program for many TVs, not just for controlling Pgen. I hope I haven’t confused you more, but its an attempt to explain to you what you are doing during the install.

Case and power supply arrived. At $5, the original Raspberry case is definitely cheap and cheerful, but its made in the UK and has the Raspberry logo, which is priceless 
Haven’t decided whether or not to pay $40 for the Argon case. It does have a fan that PGenerator can control

Thx for sharing! It’s helpful and definitely not confusing.
I can’t recall. On the LG, will the Pgen + raspberry result in a faster calibration time than the internal TPG? I rem reading somewhere it will be much faster.
can it be used to calibrate Projectors too, or just on TVs?
It’s pretty fast. There is an adjustment screen in Calman to minimize the interval between patches. You can compare both of them. If you get Ted’s version of Pgen, there are additional patterns to check your calibration. He overlays them over Pgen so you can see them while calibrating. It does seem if you have a LG OLEd, Colorspace will get you the best calibration. I’m using the new WRGB OLED meter profile

Yes, but if the projector does not support Autocal, you need to learn Desray’s skill

Was following up on this and you are right that some of the AVSForum people are saying that MobileForge is not bit perfect when used with my Apple TV 3rd generation. According to ConnecTEDDD, Lightspace Connect is bit perfect with the ATV 3rd generation and works the same way as MobileForge through an iPhone and Airplay. Interestingly, Portrait Displays who make Calman insist that they have tested MobileForge through and Apple TV with their professional equipment and say its bit perfect.
Who to believe?
I’ve compared my previous MobileForge calibration of the Panasonic OLED with the latest PGen and Pgen is better, but the previous calibration wasn’t bad either. In any case, the reason for getting Pgen is so that I can run Calman in HDR without some complex hookup with the Vertex2 that I use with the LG projector. Lightspace Connect would only have cost me USD15 for bit-perfect YCbCr, but this whole Pi project has been quite fun.

Awesome Bro Sammy! So much more to learn from you!!
U can use for both. The PGen is a generic external pattern generator that is proven bit perfect and accurate that works with many calibration software.

Good to hear its indeed faster than using the LG internal TPG.
It will be interesting to see how much time it saves for the calman home for LG calibration for the 3D LUT using the GRID! It takes darn too long currently…
ColourSpace has good reviews. But many feedback it is much more difficult to use. Not sure if it has autocal function.
Bro, I’m just journeying along like all of us. Not really sure what I am doing.Haha

Nice. Does it allow autocal with the PGen or need to do manual calibration?
Autocal as I don’t know how to do manual calibration 
So you have to download another calman license for Panasonic too?
Yes. But it’s exactly the same program. You just enter the new license number and switch the workflow
How long did the 3D LUT take on your LG OLED? Reason I ask is that Calman can only do a Matrix LUT in HDR on my LG HU810 projector because it has the older LG internal TPG. I’m hoping that I can do the 17 pt 3D LUT in HDR with Pgen, but it already takes 6 hours for me with the 17 pt LUT in SDR and if its too long, I won’t be able to complete before sunrise!
The internal TPG also calibrates with levels at 16-235, but 0-255 would be ideal for those of us with MadVR setups. Perhaps Calman can do it with PGen
