Despite having only 12.3 megapixels on its 4K-video-capable rear camera (many other 4K-video cams have 16- to 20-megapixel resolutions) 
, the LG X mach nonetheless delivers a premium Ultra HD (3840 x 2160) maximum video-recording function 
, which is met by a QHD-1440p, 538ppi 5.5-inch Gorilla Glass In-Cell IPS display that however does not even reach the average of 450 nits of brightness that prevailed at its launch time with its meek 400 nits .
Several more of its key specs include an LTE Cat 9 adapter capable of reeling in data rates of up to 450Mbps , which puts it above many of its high-end competitors, since they only settle for up-to-150Mbps max data rates (LTE Cat 4) in comparison, as well as a 32GB memory expandable by up to 2000GB .
On the hardware front, the X mach hauls a hexa-core Snapdragon 808 engine clocked at 1.8GHz with 3GB of RAM , while a fingerprint scanner for security sits under its rear camera. Additionally, the mach touts an 8-megapixel selfie shooter up front . Lastly, it comes with a respectable 3000mAh battery, though given its potentially-power-hungry screen and CPU, somewhere around the 4000mAh mark would have made more sense and that is probably why it scores only 5 hours of 3G talk time .
As revealed by its pros and cons, the X mach is a 5.5-incher aimed at high-end shoppers who are most keen on display and imaging.
