I thought I had good HDMI cables until a friend gave me an Audioquest Forest HDMI when I upgraded my TV to 4K UHD OLED with HDR. My Blu-Ray was having problems maintaining the HDR signal and the Forest had 18Gbs speed and the problem went away BUT then I decided to replace all my HDMI's and found Monoprice Premiums with same specs for like $ 12.99 each. Installed on everything and really improved the picture from my Roku Ultra's and on my PS Audio equipment using the I2S connects. Saved and fortune and got kickbutt results.
Happy watching / listening. - Shad
