Question: Hi, what is the actual weight of this item - not the shipping weight? It can't be 4 lbs
Document: Screen brightness is good even though it can't be adjusted in the configuration that was tested.4. 1920 x 1080 resolution allows for more to be seen on the screen when compared to the main monitor.5. No noticeable delay between what you see on screen and what you hear while using the included 27&#34; USB cable in conjunction with a 10' USB extension cable.6. The included smart case/monitor stand works well.7.
First off I am a consultant and a bit of a road warrior. Having a 2nd 1080p screen is worth its weight in gold.
Then I rest the monitor against the lip, not the tab inside (you will see). If I do that it rests quite a bit farther back and it is at a great angle for working.Can't wait to put this thing through it's paces.
Very well built and light weight for portability. The resolution is very good just a slight color difference from my laptop. The case works well as a stand but I bought a tablet stand to raise up so it was the same height as my other desktop monitor. I would recommend it.
:) (standard issue for most monitors on the market)Only real drawbacks:1 - You _have to_ install the Displaylink software to utilize it. And that means that some games won't work full screen until they are updated for DisplayLink by the game makers. 2 such titles: Falcon 4/BMS and Take On Mars.
Update as of April 2014Just am now wondering WHY you can't get these. It's like they don't exist any longer which makes me wonder. They sell the cheaper lower res screen but not this, and I really don't think it's a demand thing at $200 (but I could be wrong)....anyway.....I had the Lenovo LT1421 for a while and THAT was a great device. Very well made.
I'm using it on a 6 month old Asus G750 17" laptop. The laptop is brighter, but I like the color on the MB168B+ better.I purchased another stand preemptively (one of the "also purchased with" items) but the included one isn't bad. I don't know if it changed, but it has a tab sticking up where the monitor rests so it can't slide.
Several other people reported their woes dealing with drivers. I ultimately had to reset my operating system (Windows 8.1) and reinstall DisplayLink 7.4.2 drivers to get this thing to work. Until I got the right drivers, the monitor would either not work at all, or intermittently and briefly fail, usually about once every two minutes.
If you use the Y splitter, you should still use a USB hub in between the SP2 and the Y splitter so you have a port to use the thumbdrive in later.Step 4. Plug the thumbdrive into your USB hub and move the files onto your SP2. You might try moving the files to the SP2 prior to hooking up the monitor, but I'd suggest not doing it this way because it might pre-install the driver.
Display room is the reason someone would even consider these monitors, so why not get the most resolution possible that doesn't compromise visual comfort.3) 15.6 inch display. My personal preference is not to have a laptop or monitor larger than this size to carry around. As it is, this monitor is barely small enough to fit in my regular sized school backpack.4) The display is sharp, contrast is good.
Answer: The protective case weighs as much as the monitor.  My best guess for the monitor alone is 1.25 pounds.  I carry two sandwiched in a single protective case, and this is around 4 pounds
