DisplayPort adapter

[The Belgian Waffle]

Hello everyone,

 

I own a MacBook 13" 2015 and i'll probably need VGA or HDMI connection in the near future.

Since I bought this laptop secondhand, I'm not willing to buy a 40€ adapter from Apple.

I browsed through Amazon and found a couple of interesting ones that have both VGA and HDMI connection, but the reason I'm posting here is that I wouldn't want to buy a trash product, since all of these adapters come from unknown brands.

Do you have any advice, brands that I should avoid or do you own a good one?

Also, I've seen a bunch of them with a DVI port. Do you think there's a product that has ethernet instead of DVI?

 

Thanks a lot.
