Cable quality has a significant impact on audio visual content, especially with high bandwidth 4K content. Image loss, flashes, and visual anomalies such as sparkles can all be triggered by poor HDMI connections. THX certifies cables with 75 independent laboratory tests, so every pixel is faithfully reproduced.
