High-Resolution
Antialiasing 12-bit subpixel sampling precision enhances AA quality
Rotated-grid full-scene antialiasing (RG FSAA)
16x FSAA dramatically reduces visual aliasing artifacts or "jaggies" at
resolution up to 1920x1200
Display Resolution
Support Dual Dual Link DVI-I output-drives digital displays at resolutions up to 3840 x
2400 @ 41Hz
Internal 400 MHz DACs - Two analog displays up to 2048x1536 @ 75 Hz each
nView Architecture Advanced multi-display desktop & application management seamlessly
integrated into Microsoft Windows®.
Optional G-Sync Delivers Frame lock/Genlock functionality to unprecedented levels of
industrial realism, visualization and collaborative capabilities. Frame lock
allows the display channels from multiple workstations to be synchronized,
thus creating one large "virtual display" that can be driven by a multisystem
