Q: QuestionWhat would the refresh rate be if the resolution is 1080p on both hdmi outputs??

Asked 1 year ago by Louiienation.

• A:Answer Hi louiienation, we appreciate your inquiry! When using 1080p on both HDMI outputs via HDMI adapter, the refresh rate depends on the HDMI version and the capabilities of your display. Ensure that your monitor or TV supports the desired resolution and refresh rate for optimal resolution. With HDMI 2.0, you can achieve 240 Hz refresh rate at 1080p resolution.

Asked 2 months ago by KR.

Q: QuestionWill this EXTEND to 2 screens, the larger screen is 32” curved QHD 2560 x 1440p ? The hdmi extender to 4k won’t work unless is backward compatibility to 1440p and most hdmi splitters I find only go to 1920 x 1080 which is not high enough.

Q: QuestionThis adaptor says it will support two 4k monitors at 60hz. What frequency would I get if I used this device with two 2k monitors that are capable of 180hz each?

Asked 4 months ago by Josh.

• A:Answer Thank you for your inquiry, Josh! While the Insignia™ USB-C to Dual 4K HDMI Adapter is designed to support two 4K monitors at 60Hz, using it with two 2K monitors that are capable of 180Hz will still likely result in a maximum refresh rate of 60Hz per monitor. This limitation stems from the HDMI 2.0 bandwidth used by the adapter, which prioritizes resolution over high refresh rates when handling dual outputs. So even though your monitors can handle 180Hz, the adapter will cap them at 60Hz. System requirements include compatibility with Windows 11 & 10, macOS 10.2, iPadOS 12, Chrome OS version 48.0.2564.82, and Android OS 8.0. Tine| Insignia SUpport

Q: QuestionI would like to use my iphone as the source and route the view to two monitors. Is this compatible with Iphones?

Asked 1 year ago by Kojo.

• A:Answer Thank you for your inquiry! The Insignia™ USB-C to Dual 4K HDMI Adapter is not directly compatible with iPhones. iPhones typically use a Lightning port, not USB-C, for connectivity. You would need a Lightning-to-HDMI adapter to connect your iPhone to a monitor. However, some iPads with USB-C ports (like newer iPad Pro models) can use this adapter for dual monitor setups.

Q: Questionwill this work on a Chromebook / Chrome OS ?

Asked 1 year ago by Joey.

• A:Answer Thank you for your inquiry! Yes, the Insignia™ USB-C to Dual 4K HDMI Adapter should work with a Chromebook or any device running Chrome OS that has a USB-C port. Chrome OS generally supports external displays through USB-C connections, so you should be able to connect this adapter to your Chromebook and extend or mirror your display to two external 4K HDMI monitors. Just ensure that your Chromebook has a compatible USB-C port and that it supports the necessary display capabilities for dual 4K output.

Q: QuestionI bought this and am only able to get one monitor to connect. If I unplug one monitor then the other turns on, but the second I plug back in the first one then the second turns off. What is going on?

Asked 2 years ago by Hobbes530.

• A:Answer I had this problem on my Macbook Pro M3 Pro which supports 2 monitors. I had to unplug one monitor at a time and adjust the refresh rate down to 60 Hz, which then allowed it to display. However the 2 external monitors are only mirroring each other. It doesn't seem to support extending both.

Q: QuestionDoes this allow extended display to 3 screens total (Display 1 laptop left, display 2 middle screen, display 3 right screen), or only extended to one screen with the other either duplicating the laptop screen or the other HDMI screen)?

Asked 2 years ago by Anonymous.

• A:Answer With Windows 11 Home it works on my two laptops (a Dell and a MSI) to support Extended Desktop to two additional monitors in addition to the display screen in the laptop for a total of 3 screens able to display three different apps and other computer information. Once plugged in the user has to select "Extend Desktop" and click Apply in the Windows Settings/ Display section. Windows remembers the setting for the next time the computer is powered on. No experience with Apple MacBooks here; sorry
