Reliably distribute 4K@60Hz video signals to your UHDTV using this Select Series High Speed HDMI cable from Monoprice! It supports HDR and HDR10. HDR is an acronym for High Dynamic Range. TVs with HDR show a better, more realistic image with more contrast, brightness, and colors than ever before. HDR significantly expands contrast ratio and color accuracy. Contrast ratio is related to how bright or dark a screen is and color accuracy is how closely the colors on the screen match colors in real life. Bright images seem brighter, with more depth.
