Just be aware that old machines can bog way down when you start asking them to push millions of pixels. Their old graphics subsystems were never designed to handle that much data, bus widths are a major bottleneck.
Yeah that’s a good point. There’s definitely some machines in that bracket that are capable since with the right GPUs they could drive similar contemporary displays though (G5 tower with circa 2005 2560x1600 Apple display for example), and it’d be great to not be restricted to only those old GPUs to gain that capability.
For older machines even cleanly driving a new 1920x1080 display without a dongle would be a nice upgrade.
