Video playback tested on eight single board computers, including the Raspberry Pi 3 B+, Rock64, LattePanda Alpha, Asus Tinker Board, Odroid XU4, LattePanda V1.0, NanoPi M4, and the Khadas VIM 2.

All SBCs are shown playing the same local 1080p 30fps file, and then streaming the same file via YouTube. But which one is the winner?

Linux advice for Microsoft Office users, including Windows font installation, LibreOffice vs WSP Office, Microsoft Office Web Apps, running Windows office programs using Wine, and running MS Office in a virtual machine in VirtualBox.

...Zorin OS is one of my favorite Linux-based operating systems to recommend to those switching from Windows. Why? Well, it is designed to look very much like traditional Windows. With Windows 7 support ending soon, Zorin OS should feel very familiar to those moving from Microsoft’s OS. Not to mention, it is stable, fast, beautiful, and relatively easy to use...

Itsallaguess wrote:I've been reading some of the early reviews of the Pi 4B, and whilst the dual-monitor output is great, the reviews I've read seem to suggest that it's struggling to play back high-quality video media - even some 1080p stuff seems to struggle from what I've been reading.

Do you think this is something they're likely to overcome with better software optimisation for this specific release, or have they over-reached this time with wanting to claim their 4K dual-monitor achievement over the actual quality of the output itself?

Even with my reservations above, I continue to be amazed at the improvements they're making in this format of PC from each release to the next. It really is fantastic what they can achieve in that low-power / low-cost space nowadays...

Cheers,

If Upton says they will address the [Pi 4B video] performance issues post launch I'd be tempted to give him the benefit of the doubt. I'm tempted to get one for the dual monitor option.

Raspberry Pi 4 has a full-chip redesign, the first in the history of Raspberry Pi, and it's unlocked new levels of performance. Our specs & benchmarks show just how much faster Raspberry Pi 4 is

Raspberry Pi 4 vs NVIDIA Jetson Nano comparison, also including benchmarks of the Raspberry Pi 3B and Raspberry Pi 3B+. Video covers hardware specifications, Octane browser benchmark, USB and micro SD card speed tests, YouTube and local video playback, and Kdenlive performance and render test.

...As detailed by Tyler Ward, the Raspberry Pi 4 has a non-compliant USB-C charging port and doesn't work with as many chargers as it should. Thanks to the open nature of Raspberry Pi (even the schematics are online!), Ward was able to discover that Raspberry Pi just didn't design its USB-C port correctly. Two "CC" pins on a USB-C port are supposed to each get their own 5.1K ohms resistor, but Raspberry Pi came up with its own circuit design that allows them to share a single resistor. This is not a compliant design and breaks compatibility with some of the more powerful USB-C chargers out there...

The first thing I had to do was get into the BIOS Setup Utility to disable UEFI Secure Boot. That turns out to be a bit more tricky than you might think.
