Re: can I shut down and swap SD-cards?

Yes, you can shut down and swap cards to change the OS loaded on the Pi. I do it all the time. I run LibeElec/KODI on one of my Pi 3B's. I have my media on a USB thumb drive. I just add the thumb drive to the Library. File menu I think? Once all my MP3's are scanned into the library I can play them ...

Try a known working Power Supply and a known good SD card, if it still won't boot its toast.

Re: speed profit by shutdown video output

If your running your Pi headless, set it to boot to the command line interface. I do this with my weather clock PI that has a sense hat on it. To go back to the desktop GUI I just run sudo raspi-config and change the BOOT option to Desktop.

Re: Using a power supply under the recommandation

Check the "Typical bare-board active current consumption" column here, https://www.raspberrypi.org/help/faqs/#powerReqs The recommended column includes the max USB current figure. If all your connecting is a keyboard mouse or running headless, the bare board active current is likely all you need. I'...

Re: Recomendation for Bootable HDD

Ditto, You should be able to boot from the WD drives when connected to a Pi 3B. I linked there because they have the kit to power a PI and the drive from the one 3A power pack. You don't have to use a PI drive if you don't want to either. I have an external drive enclosure that has that same USB 3 j...

Re: Generic lcd screen 3.5" 26 pins

26 pins just means it was originally designed for older Pi's like the A+. Newer screens will have a 40 pin header. The header having 26 and or 40 pins is just so it fits nice and tight. I have an A+ with a sense hat on it. I put a proto hat in between the two so I could wire up a RTC. https://www.ad...

Re: Recomendation for Bootable HDD

Full sized 7200 RPM desktop drives likely will need to be separately powered. Not "likely will". They definitely will need to be externally powered as they required a 12V supply as well as 5V and lots of Amps, while the laptop drives only require 5V. (By "Full sized", I presume you mean 3½" drives,...

5400 RPM laptop drives will likely work OK powered by the Pi. SSD drives should be fine too. Full sized 7200 RPM desktop drives likely will need to be separately powered. Especially large capacity drives with more than one platter inside.

It's likely set to HDMI, you need to switch it to analog. There should be an ICON down by the clock to do it. You might have to right click on it, not sure, on my PC at the moment.
