High-dynamic-range rendering (HDRR or HDR rendering), also known as high-dynamic-range lighting, is the rendering of computer graphics scenes by using lighting calculations done in high dynamic range (HDR). This allows preservation of details that may be lost due to limiting contrast ratios.
60 fps typically, some gaming monitors can do up to 540 fps; internally, display refreshed at up to 540 fps [18] [19] 60 fps typically, some can do 120 fps; internally, display refreshed at e.g. 480 or 600 fps [20] 60 fps typically. Up to 480 fps. [21] Flicker: Perceptible on lower refresh rates (60 fps and below) [22]
This can create a potentially noticeable 30 Hz (half frame rate) flicker. Temporal dithering tends to be most noticeable in darker tones, while spatial dithering appears to make the individual pixels of the LCD visible. [1] TFT panels available in 2020 often use FRC to display 30-bit deep color or HDR10 with 24-bit color panels.
During video motion, screen tearing creates a torn look as the edges of objects (such as a wall or a tree) fail to line up. Tearing can occur with most common display technologies and video cards and is most noticeable in horizontally-moving visuals, such as in slow camera pans in a movie or classic side-scrolling video games.
High-dynamic-range rendering (HDRR) is the real-time rendering and display of virtual environments using a dynamic range of 65,535:1 or higher (used in computer, gaming, and entertainment technology). [6] HDRR does not require a HDR display and originally used tone mapping to display the rendering on a standard dynamic range display.
Current generation gaming systems are able to render 3D graphics using floating-point frame buffers, in order to produce HDR images. To produce the bloom effect, the linear HDRR image in the frame buffer is convolved with a convolution kernel in a post-processing step, before converting to RGB space. The convolution step usually requires the ...
Similar to some computer monitors and some DVDs, analog television systems use interlace, which decreases the apparent flicker by painting first the odd lines and then the even lines (these are known as fields). This doubles the refresh rate, compared to a progressive scan image at the same frame rate.
Standard dynamic range (SDR) is still based on and limited by the characteristics of older cathode-ray tubes (CRTs), despite the huge advances in screen and display technologies since CRT's obsolescence. [1] SDR formats are able to represent a maximum luminance level of around 100 nits. For HDR, this number increases to around 1,000–10,000 nits.
