I wanted to make this project mainly because my cat plays with the cables and chews the USB device; since she loves to get behind the TV she even has caused the TV fall once or twice. I too realized that since the project it is easier for me to read the subtitles of movies which I like to watch with subtitles even in my language because the TV is closer to me.

More than a project it is an idea that you can do your way. Your TV needs wholes behind to introduce screws. I think all the TV or monitors have those these days.

Supplies

Those were the one I used—the ones I bought are marked with *—:

A hammer.

Some screws.

Two brackets (the white thing).*

One hook (screw like).

Two closed hasps.

Some rope.

Scissors.

Step 1: Where I Placed the Monitor?

I needed to place the monitor near a plug and in a way that the cat could not cross behind. I was not going to need the monitor while I watch a movie, so I decided to place it in a high place. The monitor was normally on the floor.

You do not need a headache but you need to know that depending on your TV or monitor you will need to adjust color and brightness in order to watch it in certain positions;
other reminder will be if you will need to keep the base or not. My intention was to get rid of the base while hanging but I realized that it was better for my purpose to keep it because the base acts as a block giving more stability to the monitor;
you do need to remember that you will need the hook so keep it in mind before attach the brackets. I mean, be sure that you have enough space to place it behind or above the TV.

So think where you are going to put the TV monitor and attach the brackets with the screws. I did not need drill although it will do good depending on the size and hardness of the surface. I did use the hammer to hammer a little the screws in order to make easy screwing them.

Place one bracket against the wood and hammer the screw a little, finish the job with the screwdriver then repeat the process with the screw that goes underneath the previous one. Repeat the process with the other bracket. By the way, I did everything without measuring.

Step 2: Attach Now the Hook.

To place the hook just think that you need to put the rope there so the TV do not fall to the front. You need to give to the TV some degrees of inclination towards the front so think about that. If you are lost here the best way to do it, I think, it would be to place the TV on the brackets and to estimate how much inclination you want and then adjust the highness of the hook and the size of the rope.

I did not think a lot that one just estimated without measuring, so I can not provide special tips more than those that I have just said.

Again, I did not need special tools only the hammer to hammer a little the hook in order to make easy screwing it. And scissors to cut the rope.

Step 3: Now the Rope.

To finish the job just screw in the wholes the closed hasps. With a little skill place the TV or monitor in the brackets and take the rope and cut it adjusting it depending on the inclination you want to give to the TV.

Step 4: Final Thoughts.

I have used pointing hasps, I mean the part you screw, but I wanted to use flat ones because I think it will adjust better to the hole.
I want to experiment with knots: first I just tied the ropes with a simple knot. You have to be sure that they are well tied and check regularly depending on the rope. Then I tried with slipknot but you need more rope than when regular ones.
Finally, I tried to do two knots in the two ends of the rope. I think the only difference it is that you do not have to check the knots that much because they do not loosen. But you have to be careful and do big knots, enough to not pass through the closed hasps.
I thought about doing it in wood, the brackets I mean, but honestly it will cost a little more and aesthetically it is not that awful. I will love to paint the brackets, though.
