Straighten it up. Run the cables together and hide them. Common sense.

We have a lot more cables than that, but we just manage them better. 1. You need a bigger piece of furniture under that tv, so you can set things in it. If budget is an issue, you can find pieces cheap on craigslist and Facebook market place. 2. Your tv looks too high. Consider lowering it. 3. Bundle the cords so that they look less like a rat nest. Consider running some through the wall.

Cables can enter the wall behind the TV and exit the wall below. Place the exit behind a piece of furniture and you don’t have to see any wires there. Now, turning a corner with cables is more challenging, but you could at least bring those below eye level too if you can’t get them behind furniture.
Check YouTube for how-to videos, I’ll bet they have something. Or an electrician can do this for you.
