Forest HDMI embodies all of AudioQuest's core philosophies on cable design. Forest employs solid 0.5% Silver-Plated conductors, Solid High-Density Polyethylene Insulation, and precise signal geometry. Specific attention has been paid to maximizing the performance of HDMI, and indeed, AudioQuest's HDMI cables push sonic performance to new levels.
AudioQuest 18Gbps High Speed HDMI cables have the bandwidth required for video up to 8K/30 (8-bit, 4:2:0), which is 7680 x 4320 resolution (over 33 million pixels) at up to 30 frames-per-second (fps). 24 and 30 fps are the frame rates for almost all movies and many TV shows.
All AudioQuest 18Gbps High Speed HDMI cables are guaranteed to have the 18Gbps bandwidth required for compelling features like 8K/30 video, HDR (High Dynamic Range) imagery, and eARC (enhanced Audio Return Channel).
HDMI hardware’s previous ARC capabilities max out at lossy (compressed) 5.1-channel surround sound. Not only do all generations of AudioQuest HDMI cables “with Ethernet” support ARC, but in order to ensure superior audio performance, the ARC-channel conductor-pair is internally controlled for direction, running in the opposite direction from the 4 pairs that carry information to the TV. New HDMI 2.1 hardware supports Enhanced Audio Return Channel (eARC), which increases bandwidth dramatically to support uncompressed and lossless high-resolution multichannel audio, including Dolby TrueHD and Atmos, and DTS-HD Master Audio and DTS: X.
AudioQuest 18Gbps High Speed HDMI cables support High Dynamic Range (HDR) and Dynamic HDR. HDR content expands the contrast of the image for blacker blacks and brighter whites/highlights as well as greater color saturation and brightness. Dynamic HDR (HDR 10+ and Dolby Vision for example) enables frame-by-frame HDR optimization rather than HDR settings that are fixed for the entire program.
