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

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. yourUSB-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 onlyports. 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 ina Thunderbolt 3 accessory to a USB-C port, it just won't work because there's no PCIe controller in the USB-Cport. However, while you can't use most Thunderbolt 3 devices with a USB-C port, the same isn't true the otherway 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 thatsupports Thunderbolt 3 and you will only get 4K as a maximum resolution...^IFV

Select the Color Management tab,then click Color Management. Select the Advanced tab then click Calibrate display. This will start the Display Color
Calibration wizard. There are also a number of monitor calibrators such as: i) Datacolor Spyder5ELITE. The bestmonitor calibrator for professionals. ... ii) X-Rite i1 Display PRO. Another top professional calibrator. ... iii) Datacolor
