What people are saying

Rated 1 out of 5 by from No Power Waited two months for this monitor and can't get power to work. So frustrating. Customer service was not at all helpful.
Date published: 2020-06-19
Rated 4 out of 5 by from Amazing sharpness, contrast, and color gamut I bought this monitor approximately 1 month ago to use with my Mac Mini 2018 and it is the best monitor I have ever purchased. Amazing contrast, sharpness, and color fidelity. And the sound is not bad. I have only one caveat. It has not integrated 100% smoothly with my Mac Mini, an intermittent issue permitting use of Accessibility > Increase Contrast tool has required a software user account rebuild and so far Apple has not been able to isolate the cause other than help with the workaround. Also I cannot scale for 3840 (the true resolution of the monitor but only, for some reason, to 3008--however I use either the default or 2560 and this has not been a problem.)

Rated 5 out of 5 by from Easy to set up Two cables to hook up and that's it. Integrates with my MacBook without any issues. The display is fantastic.

Can this monitor be used with the different computers? Say a Mac mini as the main input, but occasionally a MacBook Air? Can I use separate cables/ports for the two computersor is there only one real &ldquo;input&rdquo; port? Thanks!

I have a Lenovo legion with usb-c will this work with the monitor not sure if usb-c and thunderbolt 3 is the samething?

Asked by: Brayan
You can plug a USB-C device and cable into a Thunderbolt 3 port whenever you want because Thunderbolt 3 fully supports USB-C. USB-C and Thunderbolt 3 both utilize the same reversible port, but while USB-C and Thunderbolt 3 port look the same, Thunderbolt 3 has some extra hardware compared to the more widely-adopted USB-C. your USB-C accessories and cables will work with a Thunderbolt 3 port. All Thunderbolt 3 ports are also USB-C ports. However, the same cannot be said for the other way around; not all USB-C ports are also Thunderbolt 3 ports. Thunderbolt 3 was developed by Intel and offers high-bandwidth data transfers between devices, with maximum transfer rates of 40Gbps (or 5GB/s) available. Importantly, it's also built on PCI Express (PCIe) and DisplayPort, and this goes to why Thunderbolt 3 cables and accessories, for the most part, aren't compatible with USB-C only ports. Because USB-C doesn't use PCIe. USB-C is merely the latest generation of the USB standard, something that's been present in everything from computers to cameras to phones for a while now. So when you try to plug in a Thunderbolt 3 accessory to a USB-C port, it just won't work because there's no PCIe controller in the USB-C port. However, while you can't use most Thunderbolt 3 devices with a USB-C port, the same isn't true the other way around. You can plug a USB-C device and cable into a Thunderbolt 3 port whenever you want because Thunderbolt 3 fully supports USB-C. Windows is officially unsupported on the LG 24 inch UltraFine 4K UHD IPS Monitor with macOS Compatibility, Model # 24MD4KL-B but the display can mostly work with a Windows PC that supports Thunderbolt 3 and you will only get 4K as a maximum resolution...^IFV
