nuc x15笔记本，作为游戏本竟然不支持独显直连？

[Kch-I]

intel nuc x15游戏本需要支持独显直连，这么好的配置价格，没独显直连太可惜了。

This laptop supports connection of external displays via both HDMI and USB-C/Thunderbolt-based DisplayPort connection. What is it that you don't like about this support?

是的，通过外部链接可以达到独显直连，但是失去了笔记本的高刷屏和便携性，独显处理完的内容要经过核显输出，核显会大大降低其性能，所以需要独显直连。

The external displays don't process anything. Are you referring to the use of an external graphics engine? Why would you want to do that when you have Intel UHD and Nvidia RTX graphics engines in the laptop itself?

No，Your translation seems to have conveyed the wrong message.When you use the original screen，graphics output by GPU must go through UHD,there is a performance penalty,especially>300fps，like CS GO.It is said that this feature can be added through a BIOS update.The “外部链接” is mean use HDMI and Thunderbolt 4.I hope this problem can be solved.

[n_scott_pearson]

Ah, I understand what you are asking now.

In the X15 design, they had to choose which graphics engine would 'own' the connection of the internal display and they chose it to be the iGFX engine. Yes, there is going to be a slight performance penalty for graphics output from the dGPU to be displayed; this cannot be avoided. The situation is similar at the USB-C connector; it would appear that the CPU design requires that an iGPU DP be utilized in this connector and will affect output to an external monitor connected to this port. The HDMI interface, on the other hand, is directly-connected to the dGPU and you aren't going to encounter this performance penalty when using an external monitor connected to this port.

It is what it is.

Yes,and the 独显直连（Graphics Processing Unit Direct）can solve this problem.Maybe update BIOS to add this function.Players need it!

The function isn't possible via a BIOS update.  The screen is physically connected to the igpu, only the HDMI is connected directly to the dGPU (nvidia card).

Laptops that support switching have a physical switch inside that changes the connection between the two.
