Does this monitor work with LG 27" 27MD5KA

[terryw1]

With this configuration of the MacBook pro?

(Mid 2015) Apple MacBook Pro 15-Inch Retina Laptop Force Touch Quad i7 2.5GHz - 3.7GHz / 16GB DDR3 Ram / 1000GB SSD / Radeon R9 M370X 2GB Video / High Sierra / HDMI / DVD±RW Drive / MJLT2LL/A

Is there a better monitor I should be looking at?
Thanks terry

Nope. Only the 2016 and newer MacBook Pros are compatible with 5K display(s). The model you listed can power a 4k display, albeit at 30 hertz as per Apple's specifications:

• HDMI video output
  • Support for 1080p resolution at up to 60Hz
  • Support for 3840-by-2160 resolution at 30Hz
  • Support for 4096-by-2160 resolution at 24Hz

The more appropriate Apple documents are:
https://support.apple.com/en-us/HT206587

https://support.apple.com/en-us/HT207448

In there, it mentions the "LG UltraFine 5K Display" which I presume is the same as the 27MD5KA. LG also has the 27MD5KA-B. In neither of these documents does Apple mention the model number - maybe they hope excluding the model makes it more likely you buy from Apple or Apple's documentation quality is getting worse. Either explanation is plausible.

In any case, neither mention the 2015 15" MBP as being able to do 5K on the UltraFine 5K. The 2015 15" MBP will do 5K if you have a monitor with multiple DisplayPort ports that were meant for that purpose. In the first document, look in the section on "Dual-cable displays".

The UltraFine 5K will do 3840x2160 @60Hz with the 2015 15" if you buy the Apple TB3->TB2 adapter and a Thunderbolt cable - so a $90 additional investment. Not a good deal unless you plan to get another Mac soon which can support 5K via a USB-C Thunderbolt cable.
