4K and HDR Support for Games
4K resolution and HDR display support have moved from premium features to player expectations — especially on console and high-end PC platforms where 4K displays are now mainstream. Implementing these features correctly requires more than simply rendering at higher resolution: it demands careful art pipeline decisions, HDR-aware color grading, and platform-specific certification compliance. Kreonit provides expert 4K and HDR implementation services that make your game look stunning on modern displays without compromising performance.
4K and HDR Services
4K Rendering Pipeline Setup
Configuring dynamic resolution scaling, supersampling (DLSS, FSR, XeSS), temporal anti-aliasing, and LOD systems for 4K output — balancing visual sharpness with consistent frame rate targets across the hardware range your players actually own.
HDR Color Pipeline Implementation
End-to-end HDR pipeline implementation — linear working color space, scene-referred rendering, HDR10 and Dolby Vision output formats, tone mapping calibration, and in-game HDR calibration UI for player display setup.
HDR Art Validation and Correction
Reviewing existing game assets and lighting for HDR correctness — identifying materials with incorrect roughness or emissive values that look fine in SDR but blow out or appear incorrectly under HDR rendering conditions.
Display Technology Comparison
| Standard | Peak Brightness | Color Gamut | Platform Support |
|---|---|---|---|
| SDR (baseline) | 100 nits | sRGB | All |
| HDR10 | 1000-10000 nits | DCI-P3 | PS5, Xbox, PC |
| Dolby Vision | 10000+ nits | DCI-P3+ | Xbox Series, PC |
| HGiG (game standard) | Variable | DCI-P3 | PS5, PC, Xbox |
Frequently Asked Questions
Does adding 4K support require rebuilding all art assets?
Not necessarily. If original assets were authored at sufficient resolution, upscaling technologies (DLSS 3, FSR 3, XeSS) can deliver excellent 4K quality from lower render resolutions. We assess your existing asset resolution against 4K output requirements and recommend the most efficient path.
How do you calibrate HDR for players who have different display capabilities?
We implement the HGiG standard in-game calibration flow — showing players peak brightness and black floor test patterns to let them configure HDR output for their specific display, ensuring the best possible experience across the enormous variety of HDR display capabilities.
Does HDR implementation require console platform certification?
Yes. PlayStation and Xbox have specific HDR certification requirements including mandatory calibration UI, correct metadata output, and handling of SDR fallback. We ensure full compliance with platform requirements as part of HDR implementation.
Can HDR be added to an existing shipped game as a post-launch update?
Yes, though it requires careful implementation. We assess the existing rendering pipeline for HDR readiness, implement the required changes to the post-processing chain and output pipeline, validate across target displays, and manage platform patch certification for the update.
