4K Output and Video Playback Capability Tested on 6 ARM based mini PCs and Boards

Since I’ve now got a 4K TV, I’ve decided to test 4K support for six different platforms based on Rockchip, Allwinner, Amlogic, Realtek, HiSilicon, and Mstar processors. For all these platforms I’ll report HDMI 4K output options, user interface resolution, and take close up pictures of the screen while displaying a 4K 1×1 grid picture and video with the image players, and video players such as MX Player or XBMC depending which are available in the firmware. Test Setup and Procedure I’m using LG 42UB820T 42″ UltraHD television with an HDMI cable connected to HDMI 1 port of the TV. Please note that my TV only support 8-bit color depth / YCbCr 4:2:0 which may cause compatibility issues with some boxes, at least the ones based on RK3288 processor, for 2160p 50Hz or 60Hz mode. I’ll take close-up pictures of the screen with a Canon PowerShot A2300HD camera by holding […]

Linux 3D GPU Acceleration Demo on Rockchip RK3288 based Firefly Board

Several devices and development boards based on Rockchip RK3288 processor already support Linux, usually with images based on Ubuntu, including Ugoos UM3 / UT3, Open Hour Chameleon, and Firefly-RK3288 among others. What these images lack however, is support for 2D and 3D graphics acceleration with the GPU, and hardware video decoding/encoding with the VPU. But Jas-hacks has made some progress with 3D graphics support. He has managed to add GPU acceleration via EGL/OpenGL ES bringing 3D acceleration to the platform, but 2D support is not there yet, meaning X11 still heavily relies on software rendering. But the implementation is still good enough to run the usual es2gears and glmark2-es2 benchmarks. as well as some WebGL demos in Chromium. Performance is currently underwhelming, with 50 points in glmark-es2, even a bit lower than the score (54 points) I got with ODROID-X board powered by Exynos 4412 SoC with a Mali-400MP4 GPU, […]

LG 42UB820T 4K UHD TV Review

After several people often asked me about audio pass-through, and 4K video support on mini PCs, with some suggesting adding a donation button to my website, I decided to start a crowdfunding campaign to raise funds for an AV Receiver and a 4K TV by asking for donations and selling some samples I used for review. Thanks to the great help of my readers, I managed to get enough money to buy LG 42UB820T on Lazada for 19,610 Baht including shipping (~$600) via 10% coupon I got in a newsletter, as well Onkyo TX-NR636 7.2 channel receiver in a local shop in Chiang Mai (Sahapanich). I’m still waiting for the speakers, so I’ll start by reviewing the TV. This model is sold as 42UB820V in Europe, and 42UB8200 in Hong Kong and probably other markets. I spent a lot of time studying about 4K TV and AV receiver features, and […]

MBX-3G is an Android Media Player with a Built-in 3G Modem (Crowdfunding)

Most full sized TV box comes with both Ethernet and Wi-Fi connectivity, but if you live in remote area internet may not be easily available, except possibly via 3G or LTE. There are several ways to handle that. You could connect a 3G USB dongle to your box, but this assume the firmware on your box supports it, or you could gt one cheap of these cheap routers with a USB port, plug the 3G dongle into it, and connect your media player to the router via Wi-Fi or Ethernet. If you’d rather have a single device with an easier setup, MediaBox MBX-3G could be an interesting option. MediaBox MBX-3G specifications: SoC – Quad core ARM Cortex A9 @ 1.6Ghz with quad core GPU (This looks like Rockchip RK3188) System Memory – 2GB DDR3 Storage – 8 eMMC flash + microSD slot (up to 32GB) Video & Audio Output – […]

Independent Dual Display Support on Firefly-RK3288 Development Board (Video)

From time to time, I’m being asked which platform can support dual independent displays, and although I noticed Mele A1000 (Allwinner A10) did support dual displays in Linux, I never really investigated how well it handles it, so I normally recommend to have a look at x86 platforms with AMD or Intel processor that specifically claim support for dual independent display. But today, I’ve noticed a developer working for T-Chip posted a nice demo on T-Firefly forums with two displays connected via HDMI and VGA. The demo shows Firefly-RK3288 development board running Android with two displays in three configurations: Display Mirroring – The same content is shown on both display. Especially useful for digital signage application, where one board can drive two displays with the same content Extended Desktop – The user interface is extended on both monitors. It’s like having a single large monitor with a 32:9 aspect ratio […]

Install Ubuntu 14.10 on MeegoPad T01 with a Live ISO Image

MeegoPad T01 has recently been shown to boot Ubuntu and Android, but no installation disk had been provided so far. But thanks to deadhp1, there’s now a “beta” Ubuntu 14.10 image with MATE desktop environment available for download in order to try or install Ubuntu on MeegoPad T01, and other Intel Atom Bay Trail-T devices. Before you decide to try or install the image, be aware that audio and Bluetooth are not working for now, but everything else should work, including hardware video decoding in Kodi. If your device is not using a Realtek rtl8723bs module, Wi-Fi won’t work, and you may need to use a USB Ethernet dongle to get IP connectivity. The instructions will keep your Windows 8.1 installation too, albeit I suppose you could also wipe out the Windows 8.1 partition completely and run Ubuntu only on the device. If the instructions are not followed carefully, you […]

Mini Review of VidOn Box Android Media Player

Vidon Box is an Allwinner A31s based TV box made by Vidon.me, a Diamond sponsor for Kodi entertainment center. I’ve already listed specs, subscriber services, and uploaded pictures in the unboxing post, so it’s time for a review. Since Allwinner A31s has been around for a while, I’ve decided to write a shorter review. First Boot, Setup, and First Impressions Since the box provides some services with a subscription, with a free 1-year top-up card included, you’ll probably want to register an account on Vidon.me first, as it’s needed to activate all services in the box as shown on the back of the top-up card. After the optional Subscription is $14.99 per year, and it’s only needed if you need features like Blu-ray navigation, or audio pass-through. The simple remote included does the job if you only use the box for settings and XBMC, but otherwise you’ll need an air […]

Understanding Windows 8.1 Licenses with MeegoPad T01 (and Other Intel Atom Bay Trail mini PCs)

MeegoPad T01 was initially announced as a dual boot Windows 8.1 and Android 4.4 HDMI Stick, and it became quite popular. But as it has recently started shipping, Android is gone, and people who receive it only have Windows 8.1 to play with. Unfortunately, as the review embedded at the end of this post clearly indicates it’s running with a Windows 8.1 trial version that needs to be activated and with an invalid serial number, so it can only be used for 30 days… Normally, I would not be so interested in a Windows 8.1 only device, but since many people seem to have acquired one, it’s probably useful to look into what can be done about the license. So what could you do? There are several options: One person decided to buy a Windows 8.1 License. Cost? $119.99 + $7.20 for tax for a grand total of $127.19, or […]
