The good news is there are already plenty of small USB-C + HDMI super wide displays at least than half that price.
There's just no way this can sell well at this price.
As already mentioned in the comments here, there are alternative small USB C screens for like half this price.
maybe a bit silly of a comment but what is the point of such a monitor?
purely to see ingame fps or see cpu/gpu temps? but you wouldn't need a 14" screen to see that right? could easily be shown at the top left/right of your current monitor?
or is there some other use case? but it'd. be really difficult to move your mouse between 2 screens? might as well spend the money getting a bigger primary monitor?
