This is one of the simplest and cheapest (for free if you know where to go) things for your computer.
Basically, this creates an extended desktop to drag and drop other browsers or programs allowing you to do multiple things at once without clicking back and forth
especially helpful for doing things and watching youtube or a movie at the same time
Step 1: Find a Monitor
You'll need a computer already with a monitor and then need to find a separate monitor.
in my case, my dad was throwing out perfectly good (very dated and huge) monitors that are basically obsolete compared to a high res flat screen of today.
Either find someone who's doing the same by throwing out a bunch of dated monitors
- Or just buy a monitor (anything really, your preference)
Step 2: Setup
Setup your new (or old) monitor next to the monitor (or laptop in my case).
Wire the power cable to a plug and wire the video cable to the computer or laptop.
Try to setup the monitors almost touching, you'll understand in a minute
Step 3: Program the monitor
Right-click and go to graphic properties
my computer had it's own program and i cannot promise you yours is the same. Anyways, go to graphic devices and you should see boxes and monitor settings. Find multiple display and check the box of extended desktop. In the drop down arrow select monitor.
Here is where your preference comes into play. Depending on which side you put the extended monitor you want to place the boxes ( you should see some boxes to the right with numbers in them) in the right places. Mess around with it until you get it right but for me, I have my new monitor on the left and therefore I placed in the the number 2 box to the left of the number 1 box.
The size of the box may be adjusted as well and that is your preference.
