This does not sound like an issue at all. If someone has their laptop connected to multiple displays, they will almost certainly be running on AC power as well, so the slightly higher power draw wouldn't be a concern. The same goes for FreeSync. If you're playing a game with FreeSync active, you will almost certainly be running it on the Vega Graphics chip anyway, so of course it's going to be powered. When the Intel integrated graphics is being utilized for light desktop tasks, there will be no need for FreeSync to be active.The integrated Intel graphics can power up to three displays, but the Radeon Graphics engine supports up to six 4K displays simultaneously. Unfortunately, the discrete Vega graphics will stay powered constantly during that somewhat extreme use case. The processors also support Radeon FreeSync Technology. Intel's HD Graphics 630 doesn't support FreeSync, so it's likely that using the feature would also prevent shutting down the Vega graphics engine, making it a power-sapping feature.
