Question: Do I still need to remain connected to the main screen once it is set up to the main screen? Thank you.
Document: This screen is the perfect size for keeping tiny programs visibly active while my main monitors are busy with full-screen programs. The screen is just right for keeping dashboards open for programs such as Teamspeak, ventrillo, and skype. I highly recommend this product for anyone who needs a simple and effective secondary monitor.
I use it as an additional monitor where I can track the S&P on the 5 minute chart while not disturbing my focus on my trading vehicles on my main monitor. It works. Picture is clear and in full resolution color. There are no power issues. A setup disk is provided but my M/S XP provided it's own drivers. There are no conflict or crash issues. The device cable is not very long. Get an inexpensive female to male extension cable on the inet if you need one.
I wish I could describe it better - but the Lilliput screen tends to be somewhat blotchier (not sure the proper term for this). Video quality is watchable, though, and I don't think that's the main intent for this unit (as compared to, say, a 7" tablet). Viewing angles are also fine, and the screen is definitely bright enough.
The USB wire that connects it seems to have large issues, even the slightest tap will cause the screen to cut out and my main monitor will begin to flicker, sometimes just for about 10 seconds, other times, until I  pick the device up , unplug it and plug it back in(can you say Recursion? ), This usually ends with whatever game I was playing finally ether black screening, crashing or just hanging up.
I had two main reasons for buying this; first so that I could compare two software apps at the same time and secondly so that when I am running presentations I can have the second screen for my notes. I have a Dell E6410 running Win7SP1 64 bit with 8Gb RAM with a standard inbuilt Intel Graphics driver. At work and home I have a second full size monitor.
It certainly is great as a second screen for having things like your IM, email, music or other support apps running. And with a second VGA attached to the laptop I have 3 screens. They provide a `Y' USB cable for older or less powerful devices where a second USB port is required to provide adequate power. I do not need it.Now the problem. The screen keeps randomly freezing.
I'm a law student doing research for a couple professors this summer. A lot of times I need a full screen on Westlaw or LexisNexis on my laptop, but I want to take notes too. Switching between the programs is very annoying (you lose your place and have to click Alt+Tab a lot), and splitting the screen up is a hassle. So, I bought the Lilliput 7" external monitor and it works perfectly for this purpose.
So I plugged it in and immediately W7 recognized the device and went out and downloaded the driver. Sometime last year MS updated their support site by adding the 5.6.31854.0 driver (the driver on the CD seems to be back at 5.2.xxx). Low and behold it worked. Screen is very bright as reported and amazingly sharp. It is a little small for what I really need but it's a case of matching form over function.
Black text in MS Word is grey, but you can adjust those settings in the display preferences. Also, you only need one USB port to power it, although the unit ships with a power cable with two USB plugs. This is especially important for me because I'm on a Macbook Air and only have two USB ports.Overall, the screen quality good.
The only use I would have for this now is for my laptop. I remember it not crashing my laptop a while ago. But still, I'm a bit afraid to plug it in to that too... :/
Answer: Nope, I have an Acer r1600 hooked up with only my USB screen. It only comes on after Windows boots up though. So you wouldn't be able to mess with the BIOS of your computer.
