Hi, I ensist you GeChic 2501C 15.6″ Portable USB Gaming Monitor [mod: link removed]. It completely fits with your needs. It comes with 15.6" display and comes with plug and play feature. So, you don't need any driver installation for it.
He was asking for 120Hz refresh rate, which that monitor doesn't have. He wants to specifically use it for gaming. While DisplayLink is not a bad protocol, it has significantly worse response time than any native interface like DP or HDMI. So saying "It completely fits with your needs." is not entirely truthful.
You're also linking to a site of questionable objectivity with no imprint whatsoever that you are the owner of (I assume). The site claims to list the best monitors in a few different categories, but doesn't do any actual testing or even link to reviews. All it does is list a few pros and cons and then link to the product on amazon with what looks like an
affiliate link, which means you get a bit of money for everything people buy from amazon after clicking it. This forum is very open to community members linking to their own work, even of commercial kind, but you have to disclose your affiliation with the site you're linking to, and if you're only here to promote your own material, please ask moderators/site staff for permission first.
And BTW, the social media links on the top of your page don't work. At least put a little effort in if you want to make a quick cash grab.
To everyone who clicked through one of the amazon-links on that site, delete your cookies from amazon and remove all items in your cart that you added to it between clicking the link and removing the cookie.
More information on why.
