I have a 2020 M1 MacBook Air with a Thunderbolt 3 compatible USB-C cable.  PbP does not display the correct resolution. Do I need a USB-C to DisplayPort adapter?  Full screen displays 3840x2160 as it should.  Side-by-Side does not.  Thank You!

Asked by: VinnB
In PBP mode on the LG 43'' Class 4K UHD IPS LED Monitor (42.5'' Diagonal), Model # 43UD79-B you are running two external video input sources simultaneously on the screen using your preferred choice of inputs so you are not going to get the full 4K (3840 x 2160) resolution for each screen. A vertical split will give you two 1920 x 2160 pixel screens (i.e. the horizontal pixels are cut in half for each screen, which is 3840 divided by two which equals 1920 pixels and the vertical pixels remain the same which is 2160 pixels)...^Ivan

I have this monitor and it is only refreshing at 30hz. How can I get it to display at the 60hz listed in the specs? I lost the manual and can't find one online.

Please visit the support page at https://www.lg.com/us/support/product/lg-43UD79-B.AUS to access the Owner's Manual. To achieve 60Hz with a resolution of 3840 x 2160 the HDMI ULTRA HD Deep Color should be set to ON.

My PC has a quad card with 4 DP outputs. I'm reading that there are problems with dp to HDMI cables being used. Does this mean I need to have a video card with 4 HDMI outputs?

Asked by: Gpk1
The LG 43'' Class 4K UHD IPS LED Monitor (42.5'' Diagonal), Model # 43UD79-B comes with a DisplayPort cable as an included accessory. Regrettably, we are not aware of the problems of using DP to HDMI cables and cannot comment on that without knowing what the specifications are for those DP to HDMI cables. The monitor also has a USB-C port on it in addition to the 4 x HDMI ports and the DisplayPort. Two of the HDMI ports are HDMI 1.4 ports and the other two are HDMI 2.0 ports...^IFV

I just got this monitor in and need to connect it to my MacBook Pro. What exactly do I need to buy in order to make this happen? I'm not tech savvy so basic terms will be more helpful.

I just purchased a 16 inch MacBook Pro and want to connect it directly with the Thunderbolt 3 cable. Will Thunderbolt 3 to Thunderbolt 3 work? Or Thunderbolt 3 to USB-C? I’m a bit confused with what the right cable I’ll need. 

Asked by: jg6021
The LG 43'' Class 4K UHD IPS LED Monitor (42.5'' Diagonal), Model # 43UD79-B is not a Thunderbolt display. The monitor has a DisplayPort, USB-C and HDMI Ports on it. You can use a Thunderbolt 3 to DisplayPort 4K @ 60 Hz Adapter or find a dock that you can make the appropriate connections with if you do not want to carry adapters around. The Thunderbolt 3 ports in the MacBook Pro and MacBook Air work with USB-C devices, which have the same connector shape. If you want to use a USB-C device, you can just plug it into one of the Thunderbolt 3 ports. No adapter is necessary...^IFV
