I think an angel loses it’s wings every time someone claims an HDMI 1.4 connection supports 4k. Technically true, but practically very unhelpful. Who is satisfied with a 30Hz refresh rate these days? I think the only reason this doesn’t get more attention is not that many people are using 4k displays with their laptops.
Get Displayport in there, whether in the form of a USB-C/ Displayport output or a full displayport connector, and then support 4k properly, at 60Hz.
I would love one of these with true 4k support. But search Amazon, and you find lots of products with these exact claims. “Supports 4k” bright and beautiful in the ad - then in the fine print “at 30Hz”.
