The maximum resolution output of the PlayStation 4 Pro is 4K.
The PS4 Pro, released in November 2016, was Sony’s higher-performance version of the PlayStation 4. Its headline display feature was support for 4K output, commonly referring to 3840×2160 resolution, along with High Dynamic Range support on compatible televisions.
That does not mean every PS4 Pro game renders internally at native 4K. Developers could choose different techniques, including checkerboard rendering, dynamic resolution, or higher-quality 1080p modes. Some titles offered a choice between sharper resolution and smoother frame rates, so the actual image-generation method varied from game to game.
The console’s output capability is also different from its internal hardware performance. The PS4 Pro was designed to deliver a better 4K television experience, but it was not an 8K machine. Its upgraded GPU, faster memory bandwidth, and support for enhanced game patches helped it improve resolution, texture quality, and performance over the original PS4.
