can I extend the desktop with this cable or just duplicate the current screen?

Yes you can definitely extend the screen. This is what I have done with my Windows 8 system.

this cable will only duplicate the current screen & it is necessary to alter the control panel in windows in order to get both screens to work properly, I used this cable to put my PC screen on my both my digital TV & PC @ the same time

Thanks for your question. You can use another cable but I would use the one that came with them. You can extend it if you need to.

no. this device willduplicate the same thing on all four monitors. whatever signal you run into it will be duplicated on all four displays. if you want to extend your desktop, spanning it over four different displays would require a video card on your computer disigned for four seperate outputs.

I believe it will always be the same. It's a 2 to 1 port so 2 screens will be duplicated

The display on the desktop needs a connection for the "monitor" which I don't believe it does.. so no...

Yep, it's possible with docks like this Dynadock, or the Plugable Dock Plugable USB 2.0 Universal Docking Station with DisplayLink DVI/VGA up to 1920x1080, Audio, Ethernet, and 4 Available High-Speed USB 2.0 Ports. You just connect the extra monitor to the dock with its own cable, then the dock to the laptop with USB. So assuming that your laptop already has an external VGA port that you can get one external monitor connected to (try that first), then the dock then allows you to add a second external monitor. Your desktop can then be set to span all three screens (your laptop screen, and the two external monitors), which is a cool setup.

Using an HDMI cable or VGA cable into the Television and under Settings in your Computer select duplicate screen.

i am displaying my Dell E6520 on dual 24" monitors connected via std VGA cables coming off the e/port. can't say how your configuration will work but mine is flawless and the extended desktop improves productivity greatly. note: only one monitor will have the start button and taskbar unless you install a utility like multimon or similar.

No, not necessarily. This will adapt from one connection type to another, it does not split the monitors itself. I used this to adapt an older monitor for a dual monitor setup but this part along will not duplicate or extend a monitor.

I am assuming you want to "extend the displays"? If this is so then no, your video card needs to have two monitor ports in order to "extend the displays". You will only be able to mirror them with this splitter.

It that you can connect two monitors. Windows 7 will allow you to either duplicate/ replicate the desk top screen or extend the desk top onto the 2nd monitor as the others have mentioned. It typically works great. Most people extend their desktop allowing them more space for viewing/working.

Yes you can extend the display. I have mine set up with 2 external 23" monitors and the Ultrabook display for extension over 3 screens.

I'm sorry but this is a splitter which will have monitor #1 mirror monitor #2. You want to have 2 VGA connections on your PC to extend desktop. You can also use a HDMI connection along with a VGA connection to extend.

You are correct, this box only boosts and splits the identical output to 2 monitors. If you want to EXTEND your desktop to a second or third monitor, and your equipment doesn't already have a dual monitor video card (or if it is a laptop), then you need a device like the Plugable (brand) devices found on Amazon, which are USB to VGA/DVI/HDMI Adapters. There are at least 3 different models, one for USB 2.0 and one for USB 3.0, at various max resolutions and prices. Hope this helps!

I don't think the adapter has anything to do with this, it is dependent on your video card and/or computer. But in my case I am able to extend the desktop to my second monitor. Replicate is also an option.

I don't have that setup but I don't see why you wouldn't. There should be identical duplicate screens.

The display work like a second screen. Like if u go into your display properties and choose extend desktop. You will see two different thing on you computer and the tv.
