Is the PS5 actually 4K?

Yes, the PlayStation 5 (PS5) is capable of 4K gaming, but it's important to understand how and when it achieves 4K, as well as the nuances involved.

PS5 4K Gaming Capabilities:

  1. Native 4K Gaming:

    • The PS5 supports native 4K resolution, which means it can render games in 3840 x 2160 pixels without upscaling. This provides sharp, detailed visuals with four times the resolution of 1080p Full HD.
    • Many PS5 games are designed to run in native 4K at 60 frames per second (FPS) or higher, giving you a smooth and visually stunning gaming experience. Some games, especially those optimized for next-gen consoles, can even run in dynamic 4K (which uses techniques like upscaling or rendering at a slightly lower resolution and then increasing it) to maintain performance while still looking close to native 4K.
  2. 4K at 120Hz:

    • The PS5 also supports 4K at 120Hz, which means it can output 4K resolution at up to 120 frames per second. However, not all games support 120Hz at 4K. For the few games that do, such as Call of Duty: Warzone or Devil May Cry 5 Special Edition, you'll get ultra-smooth motion in fast-paced gameplay. For this feature, you’ll need a 4K 120Hz compatible display, typically a TV or monitor that supports HDMI 2.1.
  3. HDR Support:

    • The PS5 also supports HDR (High Dynamic Range) in 4K, which enhances the contrast, brightness, and color accuracy of supported games, giving you more vibrant and lifelike visuals. HDR works best when paired with a 4K HDR-capable display.
  4. Games and Performance Modes:

    • Many PS5 games offer different performance modes. For instance, some games may offer a Performance Mode (usually targeting 60fps or higher at 4K) and a Quality Mode (which might render at a slightly lower resolution but with higher visual fidelity, including better textures, ray tracing, and lighting effects).
    • Some games, like Ratchet & Clank: Rift Apart or Spider-Man: Miles Morales, offer native 4K at 60fps with ray tracing enabled, while others may choose to prioritize a smoother frame rate or higher resolution.

Limitations of PS5's 4K Gaming:

  1. Not All Games Run at Native 4K:

    • While the PS5 can support 4K resolution, not all games run in native 4K. Some games may render at lower resolutions and then use upscaling techniques (such as checkerboarding) to make it look like 4K. These games can still look great, but they aren't true native 4K.
  2. Dynamic Resolution:

    • Many games use dynamic resolution scaling, which means they may fluctuate the resolution based on performance needs during gameplay. This can result in a game being rendered at something lower than 4K (like 1440p or 1800p) and upscaled to 4K. The difference is often hard to notice, but it's not technically the same as native 4K.
  3. Ray Tracing and Performance:

    • When games use ray tracing for realistic lighting, shadows, and reflections, it can put a significant load on the system. As a result, some games may lower the resolution (using dynamic resolution or lower frame rates) to maintain smooth gameplay while still having ray-traced visuals.
  4. 4K Streaming:

    • While the PS5 can play 4K media content from services like Netflix, YouTube, or Disney+, you will need a stable internet connection with enough bandwidth to stream 4K content smoothly (typically 25 Mbps or higher for 4K streaming).

PS5 4K Gaming Performance Overview:

  • Native 4K: Many PS5 games support 4K at 60fps, and some games can push 120fps at 4K.
  • Upscaling: Some games use upscaling techniques like checkerboarding to render visuals at lower resolutions and upscale them to 4K, which can still look fantastic.
  • Ray Tracing: When enabled, ray tracing can reduce the available resolution or frame rate to maintain high-quality lighting effects.

What You Need for 4K Gaming with PS5:

  • 4K TV or Monitor: To fully experience PS5's 4K gaming, you’ll need a 4K display that supports HDMI 2.1 to take advantage of features like 120Hz and 4K 120fps. Popular brands like LG OLED, Samsung QLED, or Sony’s own Bravia 4K TVs are great choices.
  • HDMI 2.1 Cable: To get the full benefit of 4K at 120Hz, you must use a high-speed HDMI 2.1 cable.

Conclusion:

Yes, the PS5 is capable of 4K gaming, but it depends on the game, display, and settings. While many games can run in native 4K, others use dynamic resolution scaling or upscaling methods to achieve 4K-like visuals. If you're looking for the ultimate 4K gaming experience with the PS5, you'll want a 4K display that supports HDR and HDMI 2.1 for the best performance in both visual quality and smooth gameplay.
