This calculator should help you determine how much bandwidth a resolution needs,
thus allowing you to more easily figure out what type of display cable you need.


Video bandwidth of common cables and interfaces (without any TDMS 8b/10b overhead):

  • VGA (DVI-A) = ~9.63 Gbit/s (~400 MHz RAMDAC)
  • DVI-D = 3.96 Gbit/s (Single Link), 8.16 Gbit/s (Dual Link)
  • HDMI
    v1.0/1.1/1.2(a) = 3.96 Gbit/s
    v1.3(a/b/b1/c)/1.4(a) = 8.16 Gbit/s
    v2.0 = 14.40 Gbit/s
  • DisplayPort
    v1.0/1.1 = 8.64 Gbit/s
    v1.2(a) = 17.28 Gbit/s
    v1.3 = 25.93 Gbit/s (up to ~80.27 Gbit/s with compression)
The bandwidth number is for progressive frames, and the assumed bitdepth is 24. If details are wrong, or the calculations are inaccurate please use the contact form and it will be corrected!
CVT-RB stands for Coordinated Video Timings-Reduced Blanking and if often used by LCDs, other types of video timings are GTF, DMT, CVT, and the overhead may vary from resolution to resolution, and with EDID the monitor itself tells the system what the timings should be, which may or may not match typical CVT-RB timings. 59.94hz may also be shown as 60hz thus adding to the confusion
Cables has a transmission overhead also, if the TDMS method 8b/10b is used for signals then the overhead is 2 bits per 8 bits, meaning 24 bit will use 30 bits of bandwidth.
This is why all numbers in this calculator is without any overheads unless stated otherwise. To compare with the cable limit, use the CVT-RB number for a close approximation.
Ironically flat screen panels require no blanking, and all this mess with video timing is a remnant from old CRT monitors.

The following is a audio bandwidth calculator, it shows you how much bandwidth LPCM (uncompressed) audio requires, any potential overhead are not included in the resulting numbers.
You can enter channel values like "2" or "5.1" or "7.1" and frequency values like "48 kHz" or "44.1" or "48000".

Audio bandwidth of common cables and interfaces (without any overhead):

  • VGA (DVI-A) = Not supported.
  • DVI-D = Unofficially.
  • HDMI
    v1.0/1.1/1.2(a)/1.3(a/b/b1/c)/1.4(a)/2.0 = 36.864 Mbit (16/20/24 bit, 32/44.1/48/88.2/96/176.4/192 kHz).
  • DisplayPort
    v1.0/1.1/1.2(a)/1.3 = 36.864 Mbit (16/24 bit, 32/44.1/48/88.2/96/176.4/192 kHz).
A DVI-D output connector can unofficially handle audio as it is electrically pin compatible with HDMI (which was based on DVI-D), a modern computer graphics card could pass audio by using a passive DVI-D to HDMI adapter.
Lossless and lossy codecs may be used to squeeze more audio data together, these are not listed here and support varies widely between standards versions and interface implementations.
The number of channels and frequencies listed for each standard is what is officially listed as being supported, implementations may support less than or more than what is listed here.
