    Title a bit misleading since it only does 4k @ 30Hz or 60Hz/4:2:0

    • Anonymous,

    Pros: Works, good for tight spaces, supports 4:4:4 chroma with audio (LPCM up to 8-channel 192KHz 24bit)

    Cons: Title can be misleading to the average Joe as this is an HDMI 1.4 devices

    Device works great for tight spaces (I only had 40mm to work with) and fully supports 4:4:4 chroma with audio up to at least 48KHz 24bit

    It must be noted that this is an HDMI 1.4 device which was more than enough for my needs (1080p TV), but it would be nice if the title for the product said HDMI 1.4 rather than "4k HDMI" as the general consumer has associated 4k+HDMI with HDMI 2.0 (regardless of the fact that HDMI 1.4 can actually do 4k).

    6 out of 5 stars

    Pros: Allows for, and works with Eyefinity triple monitor setup.

    Cons: None

    First one was having electrical errors. No products (not even space rockets) are 0% fail. Immediate RMA with free replacement. 2nd one works as expected. No hassle involved. Had reasonably fast shipping into the midwest.

    If i am not mistaken, i am getting 60hz at 1080p.

    Artifacting/Screen glitching

    • Anonymous,

    Pros: cheap

    Cons: artifacts...

    This adapter will randomly artifact while watching videos. I tried on 2 different devices with different HDMI cables and I have issues with all combinations. The devices work perfectly fine if I plug them directly into an HDMI port but because I only have one of those, I needed this adapter. It's cheap enough not to waste time and money returning it though. I'll probably grab a different one from the MicroCenter nearby
