So from what I see this GeChic product isn't a (DisplayLink) USB monitor. It's an HDMI monitor, but also uses a USB connection for the 10-point capacitive touch input as well as optional power source (it also has a DC-in port for alternative power supply). Supports Windows and Android, but otherwise you can connect this as a plain HDMI monitor.
That's right. It isn't a DisplayLink monitor, but an HDMI/VGA monitor. In practice though, I hardly think this is extremely important for my particular use case (mainly Visio, business apps, etc.) but it certainly could bother others. Like I said though, I find the display to be far superior to the TN displays that I've seen...at least according to my eye.
Per Laptop mag, the Asus MB168B+ (15.6" TN) is 14.9 x 9.26 x 0.26 inches at 1.6 lbs (15.25 x 10.75 x 0.7 inches at 2.6 lbs inside its case).
Whereas the GeChic On-Lap1502I (15.6" IPS touch) is 16.94 x 9.78 x 0.39 inches at 2.98 lbs, not including its stand.
Again, like I said, I was willing to trade the increased weight for the better display quality. It certainly is heavier than the TN (non-touch) display that I previously had, but not so much that I avoid bringing it along in the cases where I know I'll need to use it.
The Asus spec states <5W "typical" power consumption which Laptop mag claims is already too much for some computers to supply via a single USB port (they had to purchase a USB Y-cable to draw power from a second port, though the SP2 obviously only has one USB port).
The GeChic is bundled with a 5V 2A (ie. 10W) power supply, which is iPad-charger territory. If I had to guess, some computers may not be able to supply enough power even from two USB ports in parallel? If using with the SP2, I guess we have to use the alternative power supply via the DC-in jack?
It certainly does draw more power than my old TN display. Crazy thing is, that the USB port on my old SP1 was enough to drive the display by itself, but on the SP2 I do have to use the USB power from the AC Adapter to give the display enough juice to work. The included cable is a USB Y-Cable, so you don't really need to connect another cable to get it done but it can make for some interesting situations getting the brick close enough to work. I've also used a 14000 mAh battery by RAVPower to power the monitor and that works quite nicely as well. I think their specs are quoting max power draw (including speakers), so I've disabled the speakers in the monitor (which suck by the way) and just use the speakers which are internal to the SP2. This helps reduce power draw...
