Piece of junk!!! Lenovo does not stand behind their product.

Summary: Bought this item for doing work at clients as I'm used to a dual screen setup at my home office. From the start the resolution wasn't the greatest but I could live with it and it was a bit slow to respond. Used the screen maybe 5 times before the screen cracked while traveling. It wasn't subjected to anything worse than what my laptop was and that has lasted more than three years of travel without a scratch (Macbook Pro 15").
Summary: The cover issue is not an issue. Just slide it sideways and dont try to pry it open. The video quality is excellent, when working with office tools and web. The graphical performance is dismal. If running flash videos from the web (full screen) I get nothing (black screen) Running "gangnam style" on YouTube works fine, even when upscaling the window - but not in full screen flash. I wanted the monitor to run movies on the side, when working from hotels during travel.
Summary: DON'T WASTE YOUR $$. Bought this, worked great for two hours... then I tried sliding it into the case and the LCD snapped. Now it is broken and Lenovo refuses to help me. Even though it was their own cover that caused it to crack. The rep didn't even know what the product was but refused to help. I asked for a manager and was told I would get a call back, that was days ago.
Summary: This is my first time writing a review. I think it shows I frustrated I am. I purchased this product to use as a second monitor at work, mostly for viewing excel and pdf documents. It is very slim and light, and while it worked, it was great. But it only worked the first three times I used it and then for no explicable reason the screen just stopped working- It was gray and blank and I could not even get my company's IT staff to fix it.
Summary: I'll start off by saying this review is more of a warning to Mac users who are thinking about purchasing this as it is not fully compatible after the release of Mountain Lion. Upon installing the recommended drivers from Displaylink.com my Mac suffered various crashes that pretty much rendered the monitor useless. The only remedy was to uninstall the entire software. Before purchasing the Lenovo Displaylink's website had stated that it was fully compatible.
Summary: Lenovo Thinkvision LT1421 doesn't work. Purchased 200 units and they don't work in mirror mode with power Powerpoint. When you transition to mirror mode and run power point the the mirror image on the Lenovo screen starts off blank and renders as you move the mouse. It can't be used for customer power point demos. Support is non-existant. You can't call anyone at Lenovo or Display link. Stay away.
