The first thing you need to do is determine which kind of port you already have on your laptop. It can be HDMI, VGA, or DVI.
Then you have to purchase a matching cable. Once you set up the cable and monitor, go to the control panel's Appearance and Personalization and choose an option called 'Connect an external display'. Your current desktop will be duplicated on the second screen, so you need to click on 'Extend these displays'. Of course, you can adjust the resolution and the colors, so explore this section a bit and set up everything to your liking. Once you are done, you will be able to use the portable screen as an extension of. If you want to connect a broken laptop screen to another one, you can give up right away.
I already use TeamViewer and Mouse Without Borders a good amount, but I doubt its possible with those. Unless, of course, I could use TeamViewer on my main and secondary laptops, to transfer the footage, without having the full screen preview up on the main laptop.
It simply cannot be done. On the other hand, you can connect it to another monitor, or maybe a TV or projector if you are not using them at the moment and your laptop has a VGA port. HDMI and DVI ports can do the work as well, since have them. All you need is a cable and a monitor that is not plugged into another computer. If you don't have a spare screen somewhere in your house, you can always buy a used monitor online, or even look for a newer model if you are willing to spend the extra money.
To my knowledge, is the best:. No issues with unsigned drivers. No issues with aero. Free, at least current beta (working till the end of 2015) (it looks like there still would be a free-for-personal-use version after release).
Supports either windows app, or any html-5 web browser as 'client'. Windows 10 / 8.1 / 8 / 7 (x86 and x64) Cons: This tool (probably, just like all other today's tools) is unable to provide nice FPS together with high image resolution and color depth. Even if link speed itself is not the issue (e.g. If you have 1Gbps LAN connection) 'motion smoothness' is still far from perfect. So, although this solution is suitable for tasks like office work, it is hardly suitable for video/gaming. Air Display technically works!
However, I am extremely disappointed in the performance. I've got my two PCs connected via gigabit ethernet with nothing but a gigabit switch separating them, and the screen refresh is still slow as a dog. You're constantly overshooting things with the mouse because of the latency-the mouse pointer keeps moving for a second or two after you've stopped physically moving the mouse. At any rate, it does technically work and answer the question, so if you'll remove the ShareMouse and Multiplicity links from your answer I'll upvote it. – Apr 8 '14 at 19:45.
Synergy resolve only one problem. It is single mouse+keyboard controlling two or more computers. But main idea is using display screen connected into remote computer, but remotely extending main computer as its semi native display. For example many laptops and computers are able use only two monitors. For accessing 3rd monitor it is needed attach additional graphics card. It cause trouble with laptop, even with two display ports.
Many laptops has CPU or chipset limitation to two monitor. – Aug 16 '17 at 9:17. You can also do it via remote assistance, if you have a second output on your display adapter. I mean that you have to be able to hook another display to your desktop PC via cable. The remote assistant is able to show the secondary desktop (as well as the primary) even if the monitor is not physically hooked.
No third party programs required for this solution. Edit: In details, if you have a multiple outputs in your display driver but no monitors (not hooked), you can do the following (works for nvidea quadro 2000 and win 7):. go to: nvidea control panel - workstation - view system topology.
from there: (main display port) manage EDID. export EDID. same place: (secondary display port) manage EDID. load EDID. (choose the file that you saved in the previous bullet).

Now you have a 'virtual' secondary screen and you can use remote assistant to zoom to it This trick does not require admin rights nor extra software.
