Check out the abilities of PINN. The developer/maintainer regularly contributes to these forums.

Wow I thought PINN was just an installer didn't realize it also acted as a boot selector.

OS selection pre-boot on Pi 4?

Say I were to grab a large Micro-sd card with the intent of partitioning and installing multiple OS's. Is there anything like GRUB available for Pi that I can use to choose the OS before booting? I like to swap between multiple OS's (Lakka, Raspbian, Gentoo 64, Ubuntu Server) for different use cases...

Re: Why does the wireless signal from the wifi transmitter always decrease over time?

Some anecdotal evidence I've had this same issue over 2 different Pi 4's. The Wi-fi signal will go fine for a while and then suddenly decides to quit working. Happens in Raspbian, Gentoo, and Lakka.

Re: Running the Pi 4 at 120hz?

Is it actually accepting a 120Hz signal? It'll probably need you to do a custom mode using hdmi_timings There is a 120Hz mode but it is 1080i. Who knows, if it doesn't oh well. I've seen some workaround to force screens with the ability to run at 120hz to accept a 120hz signal (you need a Windows P...

Re: Raspberry PI 4 vs Smartphone

When it comes to relative power (ex in calculations/a set period of time) most mid-high end smartphones absolutely decimate the Pi especially on the GPU side. Only phones that will be slower would be low end cheap devices. Remember, you're comparing a $35 computer to $300-$1000 phones.

Re: Pi 4: Is there any performance penalty to running a second screen?

The main penalty with be SD Ram bandwidth I suspect. Grabbing the data for two full 4K displays from memory and stuffing it out at 30Hz is a huge hit on that. Whether that will be noticeable in your use case is difficult to tell. However, running one display at a lower resolution will help a lot. T...

Pi 4: Is there any performance penalty to running a second screen?

Re: Help! Minecraft Server (no access outside my home network)

You said you opened the ports on your router but did you forward them? All 25565 traffic has to be redirected to your Pi via your router. Also make sure you're giving your friends the *external* IP of your network.

Re: Would There Be Any Compatibility Issues With Using A 256gb Micro Sd On A Raspberry Pi 4?

Nah, but be wary of Micro SD cards on Amazon they've had issues in the past with mixing fake cards even into batches shipped and sold by Amazon due to the way they allocate warehouse stock. You won't realize there's an issue until your card starts overwriting data.

Re: What pi has the best performance/watt?

The question is underspecified. What is "performance"? Is it idle run, heavy run or 100% for the CPU(s)? What should be computed in order to compare? Without anything meaningful to compute, Pi2B would be best with only 400mA for 400% CPU: https://www.jeffgeerling.com/blog/2018/raspberry-pi-3-b-revi...

Re: Does CSR V4.0 dongle works on Raspberry Pi 4 model B ?

It's dependent on the device itself. For example, many barcode scanners I've used register with an OS as a keyboard and just spit out plain text. If that's the case it would. But if it needs specialized software then probably not unless someone's compiled a version for armv8/7h linux.
