I have a 2015 13" MacBook Air with 2.2GHz CPU running MacOS Sierra. I also have a Thunderbolt Display (at 2560x1440), but I would like to get a new LG ultrawide monitor. Apple's webpage for the MacBook Air says: Dual display and video mirroring: Simultaneously supports full native resolution on the built-in display and up to 3840 by 2160 pixels on an external display, both at millions of colors So does that mean my MacBook Air can drive either of these LG monitors? If so, what video adapters would I need (for HDMI 2.0 and DisplayPort)? LG 34UC98-W (3440x1440 via Thunderbolt 2, HDMI 2.0, DisplayPort) LG 38UC99-W (3840x1600 via HDMI 2.0, DisplayPort) Thanks for any help.
