The display specifications of the Samsung QN85QN1EFAF and Samsung QN85QN70FAF are remarkably similar across the board. Both share the same QLED Mini-LED LCD panel at 84.5″, a native 3840 x 2160 resolution at 52 ppi, a 144Hz refresh rate, 10-bit color depth with 1.07 billion colors, and identical HDR support — covering HDR10, HDR10+, and HLG, but not Dolby Vision. Both also feature anti-reflection coating, an ambient light sensor, and wide 178° viewing angles in both axes. In practice, this means both televisions will deliver a virtually indistinguishable picture quality under controlled conditions.
The sole differentiator lies in adaptive sync compatibility. The QN1EFAF supports AMD FreeSync, FreeSync Premium, and FreeSync Premium Pro, while the QN70FAF replaces base FreeSync with Nvidia G-Sync compatibility, while retaining FreeSync Premium and Premium Pro. For PC gamers, this distinction is meaningful: G-Sync compatibility broadens the TV's appeal to users with Nvidia GPUs, whereas the QN1EFAF is strictly AMD-ecosystem friendly at the base tier. Both remain equally capable for AMD Radeon users at the Premium and Premium Pro levels.
If gaming with an Nvidia GPU is part of your use case, the QN85QN70FAF holds a clear edge thanks to its G-Sync support. For AMD GPU users or those who primarily watch content, the two televisions are effectively tied on display performance, with every other panel specification being identical.
