My laptop is HP Probook 450 G5. It has HDMI 1.4b and USB type-c with DP alt mode. I want to connect this laptop to my Samsung NU7100 TV which supports 4K@60Hz and has HDMI 2.0 ports. When I connect the TV via a HDMI cable, it only can run 4K@30Hz.
Can I take advantage of my USB Type-C port with DP alt mode to achieve 4K@60Hz? What cables or adapters do I need if this is possible? Can there be issues when connecting multiple converters? (Like USB Type-C -> DP -> HDMI). Also, does my USB Type-C support HDMI in alt mode as well?
USB Type-C is only a connector. You are getting the max possible for HDMI 1.4b, and for getting more you need HDMI 2.0. – harrymc – 2019-02-01T13:44:28.073
@harrymc but since USB Type-C supports DP doesn't that mean it can achieve 4K@60Hz theoretically? – k9yosh – 2019-02-01T14:25:04.327
You can just query on Amazon for "USB C to HDMI Adapter 4K@60Hz" and get lots of results, but these cable+adapter have very cheap in-built video processors. Don't expect any performance like what you get from a real video card. – harrymc – 2019-02-01T15:04:36.770
@harrymcI found that Accell has products that supports this. And it is certified by VESA. So that should work I guess. https://www.accellww.com/collections/adapters/products/displayport-1-2-to-hdmi-2-0-adapter

@harrymc Type-C becomes the video adapter, yeah? correct me if I'm wrong – k9yosh – 2019-02-01T15:33:03.423
No, it's just a port, no inbuilt adapter. Don't confuse yourself. – harrymc – 2019-02-01T16:28:03.687
A port passes information, it does not create it. – harrymc – 2019-02-01T17:02:12.963
@harrymc so If I buy an adapter like this adapter it should work yeah? since the adapter does the switching or conversion it requires?
