NUC11PHKi7C input lag

[Max_ap]

Hello,

I have a NUC11PHKi7C which is suffering time to time of input lag (mouse and keyboard). I've read around old post regarding input lag problem with Nvidia graphics cards, but I don't have found a solution yet.

Nvidia drivers are the lastest updated from Nvidia app.

I'm not completely sure if the lag is there after the Nvidia card is used instead of the embedded intel video card, but I have that suspect. 

The problem is more frequent or noticeable when file explorer is open and working on moving files, but it's not always laggy.

Has anyone a similar problem and found a solution?

Thank you

I'm assuming that you are using wireless mouse + keyboard, connected to NUC with USB Wireless Receiver.  If this is the case, try to insert this receiver into front USB port or even better in a distance from the NUC - on USB HUB or using USB Extender Cable (this is an example only).

Yes, correct. I use a Logitech Unifying receiver.

Using the front port is just for shorter distance/less interference?

In another nuc (10th gen not 11) I have a similar configuration but no problem at all. 

Thanks

I think you forgot to mention that you are using a wireless mouse and keyboard, in that case you are experience "USB3 interference" which is a well know problem when connecting a wireless dongle to a USB3 port.
Possible solution are to use a long extension cable, or using the internal USB2 port via an adaptor.

Yes, correct. I use a Logitech Unifying receiver.

The long extension cable is for reducing interference putting the receiver far away? Would a USB hub with 2.0 port help?

In another nuc (10th gen not 11) I have a similar configuration but no problem at all. 

Thanks

Hello @Max_ap 

Yes, the interference are probably causing this problem.  More information you may find here: Wireless product not working properly when also using a USB 3.0 device and here: USB 3.0* Radio Frequency Interference Impact on 2.4 GHz Wireless Devices

I got an extension cable. I will check if it occurs again or not.

Thank you

The Intel white paper has been moved to the USB.org site. Here is updated link: White Paper: USB 3.0 RFI Impact on 2.4 GHz Wireless Devices.

I used the extension cord. The problem still appears randomly, so maybe it was only partially determined by an interference.
