Frequently Asked Questions - NS-431H Newstar
How do I install my Newstar NS-431H KVM switch?
Connect your keyboard, mouse, and monitor to the console ports on the switch. Then attach up to four computers to the HDMI, USB, and audio input ports. Finally, connect the switch to power via the included USB line if required.
How can I switch between computers connected to the NS-431H?
You can switch by pressing the push button on the front panel or using the keyboard hotkeys (e.g., Scroll Lock + Scroll Lock + 1-4) to jump to a specific port.
Does the NS-431H support 4K resolution?
No, the NS-431H supports a maximum resolution of 1920x1080 at 60 Hz. For 4K needs, consider other models.
Can I use a wireless keyboard and mouse with this KVM switch?
Yes, because the switch uses a standard USB HID interface, your wireless receiver will work as long as it is plugged into the console USB ports.
Is the NS-431H compatible with Mac computers?
Absolutely, it works with macOS as well as Windows and Linux without extra drivers.
Does the KVM switch need an external power adapter?
The switch is mostly bus-powered, but if your USB devices draw more current, we recommend using a 5V DC power adapter (not included) to ensure stable operation.
How do I switch the audio source along with the video?
The audio inputs are linked to each port, so when you switch to a computer, both the HDMI video and 3.5 mm audio are switched simultaneously.
Are there any LED indicators to show which port is active?
Yes, each port has a blue LED that lights up to indicate the active computer.
What should I do if the monitor shows no signal?
First, verify all HDMI cables are securely connected. Then check that the correct input source is selected on your monitor. Try switching to another port to see if that works.
How long is the warranty for the Newstar NS-431H?
The product comes with a 1-year limited warranty, covering defects in materials and workmanship under normal use.
