I’ve had a Gigabyte Brix GB-BKi5HA-7200 for a while now.
This is about the 3rd Mini system that I’ve had. Maybe fourth if you include one that I built from parts. This one has:
- Intel® Core™ i5-7200U Processor
- 8GB RAM
- M.2 120GB SSD
- 60GB 2.5 inch SATA SSD
Linux Mint Fails in 4K
It was running Linux Mint 18 and recently Linux Mint 19. And this was working fine, except recently I upgraded the monitor to a Samsung 40″ 4K TV – UN40MU6300FXZA. I found the Refurbished TV for about $290 for sale by Walmart a couple of months ago. This is quite a good price for this Samsung 6300 level TV.
Since I use this mini system to display photos and game screen shots a large high-rez display is just the thing. However, Linux Mint has never supported the display correctly.
As you can see, when in 4K [3840×2160], the display is sliced up and repeated across the screen. It works fine in 1920×1080 mode on Linux. From all the reading of the processor and TV specs, it looked like it should work fine and when I use a long HDMI cable to plug the TV into a Windows 10 system with a GTX 1060 card, it works fine too in 4K.
I am using a pair of 2K monitors through a IOGear Displayport switch and Linux Mint works just fine with that using a GTX 1050 card, which has DisplayPort output.
After spending a couple of days on various forums trying to understand and fix the problem on the BRIX with no luck, I had the bright idea of just trying Windows 10 directly on the system. So I made a Windows 10 install Thumb drive, removed the M.2 Sata, to avoid messing up the Linux Install with Windows 10, and installed Windows 10 on the 60GB SATA SSD. Worked like a charm and brought the monitor right up in 4K without problems.
