I've had several mobile monitors that utilize DisplayLink over the years, this is my fourth so far. In the past, I started with the 14inch Lenovo LT1421, I went to 15.6 inch HP, then finally to the 14 inch HP S140u before moving to the ZenScreen. Each had their upsides but all had basically the same downside, resolution and color quality. For comparison the only one fair to benchmark the ASUS ZenScreen against (from what I've used) is the HP S140u as that is still available for sale by HP. The ZenScreen is worlds better. First off, with such thin bezels on 3 sides of the ZenScreen, you get 15.6 inches of screen instead of 14 inches of screen for almost the same total size, a huge plus. Secondly, the ZenScreen actually fits better in my bag even though it is marginally bigger overall; it is very thin for being a monitor and most important to me is the thickness is consistent across the unit. The HP had a rounded back that made it less convenient to have in my laptop bag and created a strange "bulge" when all packed up. That, plus the ZenScreen is just a bit lighter, was a win on its own.The most important factors here though are resolution and color quality. The resolution is full 1080p which is far better than what I've used in the past. There is no resizing of documents etc when you drag something over from your primary laptop monitor (granted their may be a little bit depending on the resolution of your laptop but at 1080p this is very minimal and hardly noticeable from other models, such as the HP S140u I've dealt with). I realize ASUS has other screens with 1080p but their stands before the ZenScreen are so ridiculous and non-user friendly, I always avoided them. On that point, the stand on this screen is pretty smart. Some point this out as a flaw but honestly in the mobile monitor space, no one has a perfect solution (the S140u wasn't bad as it had a similar concept, but still I think ZenScreen is superior). The stand is effectively the case that wraps around the unit and with a few simple folds, strong magnets hold it in place as a stand. There are two degree's you can have it at (at least, with the fold option I prefer - I guess there are a couple in the instructions only one of which I remember) and they seem to be all I need (I really only change the angle if I am experiencing glare); Oh, and you can also use a pen if you prefer to prop this up - I've yet to use this as the case is so quick and effective to fold, but an option none the less. As for color quality, I am not an expert on the levels etc but this screen, although the colors are a little different from my laptop, are the best I've experienced in a mobile monitor; there are settings you can play with native to the screen that allow you to adjust certain aspects which was key in getting the colors to line up pretty well. Again, not perfect compared to my laptop monitor but close enough where after the first week of using it, I didn't even noticed anymore.All in all, this monitor is easily worth the $250. In my experience, it is the best I've used and I'll use it until something eventually is more sophisticated, but I suspect this won't be for a while as this screen (compared to others I've used) seems ahead of the game.
