Dell_XPS_15_9550

There is a lot of good points about the device:

  • high performance
  • high resolution
  • tiny display borders
  • bright display colors
  • keyboard backlight
  • chasis materials
  • ~4h batery life (84Wh)

And some points that is not that good

  • glance display reflect light
  • touch screen cause fingerprints on display
  • tiny borders on touchscreen cause touches when change display angle
  • low HiDPI suport in Windows environment
  • lack of Ethernet port
  • Unavailability of dock accessories on Ukrainian market
  • Windows 10 HOME (that is not support virtualisation and bitlocker)
  • Long boot (15 seconds of BIOS POST)

Also there are McAfee Antivirus and additional DropBox space as a bonux for 1 year.

HiDPI compatibility

Windows, Windows applications, Java applications, sites, etc need may or may not be HiDPI aware. The issue with browsers is just about images that may (and one day will) be better for high resolution clients. The issue with OS and application are more painful. A lot of application just not usefull anymore on 15″ 4K display. OS trying too zoom Windows application to work with high DPI. For some it works, for some not.

Top Speed UHS-I U3 microSD 32 GB

Best microSD cards, that may be found today at stores is UHS-I with sequental read/write speed about 80-90 MB/s. To achive this read/write speed cardreaders must support at least UHS-I standard and be connected using fast interface like USB 3.0 or better. Use of old readers will reduce speed to about 20 MB/s. Use of USB 2.0 with UHS-I reader gives about 40 MB/s

CarDV Player 2.2

Standart player for NOUS NF9 (SAMOON B03F) is kind of minimalistic one. Firmware contain some older version with internal numbers 5.5.0. CD shiped with DVR contain newer v2.2 with internal numbers 5.7.1. Both are looks more or less same.

And contain same bugs with google maps integrations. That makes work with this application painful.

Compact DVR with Ambarella A7LA70 and Omnivision OV4689. Have small LCD with plastic cover and tiny accumulator. Also have external GPS in the middle of the power cable. GPS and DVR holder compatible to Koonlung C-series DVR. Some special “soft touch” plastic that looks like leather on device’s front. Loud speaker. SDXC support. Work with exfat 128 GB cards. It is hard to release DVR from holder even using 2 hands. Device is not compatible with iPad and Lightning to SD Card Camera Reader because of long filenames (maybe fixed by firmware customization, see end of the post).
