I have an Asus VivoBook 15 X510UR-BQ166T (Intel Core i5-7200U 2.50GHz, NVIDIA GeForce 930MX 2GB GDDR5, RAM DDR4 8GB, USB 3.1 Type-C, HDMI) and recently bought a LG 32UD59-B (31.5" UHD 4K, AMD FreeSync, DisplayPort, HDMI 4k), which I'm still waiting to be delivered.

Immediately after buying it I was quite concerned about a question: is it possible to use the monitor in 4K resolution and 60Hz without a DisplayPort? I couldn't find the HDMI version supported and I don't know if USB Type-C could stream in 4k. I chose this monitor precisely because of its image quality, response time, pixel density, size and resolution, and I may have had a terrible deal if I can't use it with my laptop.

I don't plan on playing hard games or using modeling programs, I just wish I could read, code and watch movies without seeing pixels or waiting for the mouse to move, which pisses me off a lot.

If my fear is real and I can't really connect it directly, is there any kind of passive/active converter/adapter or dock station that I could use to get the most out of the resolution? I don't understand how this would be possible since the limitation should be the laptop's connector output speed, but I've seen some people comment on this and I was quite confused.

Does there seem to be any workable solution or should I start thinking about returning the monitor before the company actually delivers it? Here in my country this kind of hardware is very expensive, and exchanging products is always a complicated issue, which is why I am concerned.

  • If your USB port supports display output, your USB C port is DisplayPort, just with a different connector. It can stream the same things DisplayPort can, becuse it is the same. However, not all USB C ports can be used as a display output (unless you use some kind of USB graphics card in between).

    Thanks @Peter! How can I find if my USB C port can be used as a display output? And what do you mean by some kind of USB graphics card in between?

So I've done some research and your monitor supports hdmi 2.0 and display port 1.2, both of these can play 4k @60hz, I could not find out what type of hdmi your VivoBook is so not sure on that but anything 1.4 or later should do 4k. As for the usb-type C, the VivoBook is 3.1 gen 1 where as in order to get a display output you need a usb thunderbolt 3, so while a type c to display port would fit in your VivoBook it will not give out a display. I will continue to look for the type of hdmi on the vivo and let you know if i find out but for now the only way you can connect to the monitor is using that hdmi port.

  • Note that for HDMI, v1.4 will support 4:2:0, 2.0 and higher will support any. You will need a cable rated Premium for 4K60 HDR (or basically any content requiring HDMI 2.0 bandwidth). For 4K60 SDR, you can probably get by with a cable rated High Speed. But if you need to buy a cable and the VivoBook supports HDMI 2.0, it might be worth just getting a Premium one to avoid needing to upgrade later since the monitor supports 2.0.
