after a month of use
UHD Display – 3840x2160 very sharp with no light bleed-through. However, most console mode software still can’t handle 3840x2160. After lowering resolution to HD mode (1920x1080), games work better.
NVIDIA GPU – Choose default GPU using NVIDIA Control Panel “Manage 3D Setting” or with a right click. Intel GPU is fine for web browsing. Install latest Intel generic video drivers to eliminate minor video glitches.
Hard disk – System has empty space for an m.2 SSD (SATA mode, not PCI-Express mode) (22mm by 80mm).
Access to innards – Easy!
Touchpad – Works well. To disable Touchpad if have a mouse connected, turn off “Leave touchpad on when mouse is connected” in “Mouse and Touchpad” settings in Settings / Devices. Similar option to fully disable Touchpad in Control Panel / “Windows Mobility Center.”
Keyboard – Works well, though key press travel is limited by chicklet style keyboard. WASD keys play games well. H and J keys get warm when gaming. Palm rest stays cool. Control FN multi-keys and key backlighting through Control Panel / “Windows Mobility Center.” Backlighting turns off when if you stop typing for a bit and then restarts when you resume typing.
CPU Fan – System fans do not turn on, except when gaming or doing something complex. System fans are noticeable, but not harsh, but will drown out normal speaker volume. An SSD will cut fan use when browsing.
Memory – Ships with one 8GB memory chip (single channel DDR3L 1600MHz) with an empty slot for another 8Gb chip (system max is 16GB total). Two chips make system notably faster.
Webcam – Uses Win10 “Camera” applet. Pictures are grainy.
Microphones – Poor. Picks up system hiss, even with “Dell Audio” settings.
