Hi! I work at Level1. Hopefully I can help you out.
First of all, I have a post with all kinds of information & educational videos here:
I highly recommend reading that and watching our videos, but I will try to give some direct information to you.
I’m not sure what you mean by “limit” gaming or performance? I can give you some facts that hopefully answer your questions though.
The KVM tries to be as passive and non-intrusive as possible to avoid conflicts. It is just redirecting your signal.
- The DisplayPort 1.4 KVMs are all completely Nvidia G-Sync & AMD FreeSync compatible.
- Make sure you have good quality cables & you will have no problems achieving up to 4K/120Hz (No DSC) or up to 4K/240Hz (With DSC).
If you are meaning “performance” as in changing FPS rates in games or causing lagging, that is a non-issue. The most prominent problem you could potentially face is not getting the refresh rate to be as high as you’re hoping for without it visibly struggling. Most of the time, that problem stems from your cables. They’re not created equally & easily can cause problems.
If you have any issues we do accept returns, issue RMAs, and offer support through email.
Please let me know if you have any questions!
