    Problem: I would like to have more pixels than my laptop provides while travelling. 2M (~1920x1080) pixels if possible. I posted searching a solution to this forum before.

    Challenges: monitors are fragile and their stands are heavy. A travel cover and a lack of stand / easel stand would help.

    Solutions: so far, none. The available USB monitors are expensive while low resolution (1366x768 is typical even for 16" models). The Samsung LD220G is the only high res monitor which is somewhat suitable for travel. However, it's too big and has no cover.

    Lightbulb moment: the Motorola Lapdock 100 is a) a normal HDMI monitor with a 1366x768 resolution at 11" b) the keyboard serves as a cover as well. Not too bad PPI wise (140PPI). Weight is very agreeable too. Since it's been discontinued, the $50-70 price is very, very good.

    Lightbulb moment no2: there is (and I already have one) an inexpensive device which allows a single DisplayPort to drive two HDMI ports, the Zotac DP2HD.

    Action taken: bought two Lapdocks off eBay. Got two sleeves 12'' Black/Red Laptop Notebook Reversible Sleeve (credit for that goes to xda-developers - View Single Post - Lapdock Sleeve ) which fit snugly. For cabling, I bought two micro HDMI female to normal HDMI female converters HDMI Adapter, HDMI Female to HDMI 1.4 A type Male Adapter Convertor | Meritline.com

    Results: Linux reports I have a 2732x768 (1% more pixels than 1920x1080) monitor connected to DP1. Cos each is 1366*768 and the Zotac adds em up. The resulting ultrawide screen is almost exactly 21" across. Short of wanting to watch a full HD movie, this is the same as the Samsung expect it easily fits in your carry-on or even daybag. And, it gets an uncompressed digital signal instead of the VGA / DisplayLink the Samsung offers. Half the weight of the Samsung too (each lapdock is 2.4lbs, the Samsung is 10lbs).

    Further problems:

    1. the AC adapters are cloverleaf -- three pin plugs are simply harder to travel with. Talked to Motorola, the charger tip is 3.5mm / 1.35mm which is very rare in a 19V setting. Possible solution: 1.7mm/4mm female to 3.5mm/1.35mm male tip from Bixnet plus a HP Mini AC adapter. Alternatively, 5.5mm/2.5mm female to 3.5mm/1.35mm male also from Bixnet and an MSI Wind / Asus U20A AC adapter. Much cheaper converters exist from 5.5/2.1mm but it seems that plug size is not available in a lightweight, cheap ~30W 19V AC adapter (65W Acer adapters seem to use it). It seems some Sharp laptops and Dell Lattitude LT is using 3.5mm/1.35mm tip but they seem to be 22V and that scares me.

    2. The micro HDMI adapter and especially the HDMI cable plugging into it is tugging at the small male connector. Many solutions are available. The best seems to be micro HDMI extender cable on eBay. Ideal solutions would be either a) a thin normal HDMI male to micro HDMI female cable b) micro HDMI female to mini HDMI female and then a super thin cable HDMI-mini HDMI cable. Neither a) nor b) seems to exist. Very hard to Google for.

    3. Some sort of laptop stand would be great to elevate the monitor. The Lapdock only opens to ~135 degrees so instead of putting the keyboard at an angle and then let the monitor stand vertical (my ThinkPad can do this as it opens to close to 180 degrees) some sort of raising platform would be required. Challenging cost and weight wise.
