TPU brings attention to the fact that NVIDIA's new GeForce GTX 980 and GeForce GTX 970 cards feature DisplayPort 1.2 connectors, and not DisplayPort 1.2a, a requirement of VESA's new adaptive-sync technology. The website suggests the prime reason for this may be that NVIDIA wants to rake in G-Sync royalties and doesn't want to support VESA's royalty-free alternative.
When asked by Chinese publication Expreview on whether NVIDIA GPUs will support VESA adaptive-sync, the company mentioned that NVIDIA wants to focus on G-SYNC. A case in point is the display connector loadout of the recently launched GeForce GTX 980 and GTX 970. According to specifications listed on NVIDIA's website, the two feature DisplayPort 1.2 connectors, and not DisplayPort 1.2a, a requirement of VESA's new technology. AMD's year-old Radeon R9 and R7 GPUs, on the other hand, support DisplayPort 1.2a, casting a suspicion on NVIDIA's choice of connectors. Interestingly, the GTX 980 and GTX 970 feature HDMI 2.0, so it's not like NVIDIA is slow at catching up with new standards. Did NVIDIA leave out DisplayPort 1.2a in a deliberate attempt to check Adaptive Sync?
