Question A laptop to output 4k at 120Hz with external monitor?

[ressys]

Hello,

I read that even if you have a laptop that runs at the resolution of 3.200 x 2.000 max, connecting it to a 4k 120Hz monitor, you can output that resolution and Herz, provided you have the right port, cable and laptop performance.

Is that correct? I am looking at an ASUS Vivobook S 16 OLED ( Core Ultra 7 155H, Arc, Thunderbolt 4, 16GB), but I doubt it can do the thing. What is there to know? What laptop could handle the task?

Thanks in advance.

Don't know where you read that. But if you read Intel's specs for the Core Ultra 7 155H

https://www.intel.com/content/www/u...-24m-cache-up-to-4-80-ghz/specifications.html

the 120Hz spec only applies to the laptop's built in display panel. For the HDMI output the spec indicates 60Hz is the max.

Can't you use the Thunderbolt 4 port?

I already use a USB-C to HDMI adapter on my desktop for 4k 120Hz, because my RTX 2080 doesn't have HDMI and my LG C1 lacks a Displayport.

The manual does indicate that you can use the Thunderbolt port but does not say anything about what resolution and refresh rate you would get from that port. You'll have to find someone who has already tried it.

I hoped to find someone like this here. Asus wont answer my inquiry. Only option left is to purchase a unit and test for myself, but then if it fails the test I will wonder whether it is the device, or the cables I used. So a definitive answer to the question would still be desirable.

A question for your question.
What would you even need 120 for ?
