AMD Eyefinity 3.0 Allows Mixed Resolution Support
Ryan Martin / 6 years ago
AMD is set to release the third generation of its custom multi-display technology, Eyefinity 3.0. The third incarnation will bring new optimisations and features to the mix with the headline change being support for Eyefinity with displays of different resolutions. This mixed resolution support will be implemented in three different ways: fill mode, expand mode and fit mode. The first of those, fill mode, utilises the full resolution of all displays but as a result of that the resolutions created are not quadrilateral (i.e. are not rectangular). The next mode, expand mode, creates a rectangular resolution based on the vertical pixel count of the highest resolution display and the combined horizontal width of all displays. The resulting area that the smaller displays cannot show is designated as “unavailable area” because the displays lack the resolution to project it.
The final method is fit mode by which the vertical pixel counts are kept constant across all three displays so it will use the maximum common vertical height. In the example below you can see that you’d end up with three 1080p height screens but the middle one becomes 2560 x 1080. This differs to previous Eyefinity where it would simply set the middle display to 1920 x 1080, now you can use the extra width by sacrificing the height which is preferable to sacrificing both.
The most interesting of the potential uses for Eyefinity 3.0 is the ability to create Eyefinity resolutions from displays of the same panel resolution height. This means gamers with a couple of 1920 x 1080 displays can add a 2560 x 1080 display to their configuration and use it fully, or gamers with a 1920 x 1200 display could buy a couple of cheaper 1600 x 1200 displays to add to their existing set up.
Eyefinity 3.0 will arrive with the AMD Catalyst 14.6 driver package which is expected in June 2014.
