Help me better understand what you are saying. Your response implies the Redmere Ultra Slim Active High Speed HDMI Cable (purchased from Monoprice) provides equal performance as my Monoprice 24AWG CL2 High Speed HDMI® Cable. If such is true then why aren't all non-long length HDMI cables ultra slim?
High speed
passive hdmi cables are currently certifiable for up to 25'. That means that the cable purchased, for the length purchased, are basically "guaranteed" to meet HDMI 1.4/2.0 hardware specs. At that length, any gauge should work just fine. At 25' and above, you
may need a cable with a thicker gauge to meet the HDMI 1.4/2.0 specs. CL2 is for in-wall installation.
Active cables, such as Redmere, can meet the HDMI 1.4/2.0 hardware specs because they draw a little power from the sink end (tv side) so they can transmit the signal at longer lengths without loss, and the cables can be a smaller gauge because of the active component.
Again, how long is your run and how are you installing your cables?
