Wait for a Display Upgrade
The 2020 MacBook Pro 16 will reportedly come with a mini LED display. This is likely coming in Q4 2020, so it is a year out at this point, but it will rely on this new screen technology according to Ming-Chi Kou.
The mini LED technology can deliver a wide color gamut, better contrast ratios, HDR and local dimming. It may also allow for thinner display panels and better power efficiency.
Kou also predicts this technology is coming to the 2020 iPad Pro in Q3 2020. It's unclear if this tech will make it into a smaller MacBook Pro in 2020, but it is likely going to debut on the 12.9-inch iPad Pro and the 16-inch MacBook Pro and then trickle down.
