Maybe it’s only improving video resolution. Perhaps the mind tends to focus on the color contrast being presented once the overall video signal resolution is improved.
Paralleled HDMI Cables Connection Improves Video Quality
I obtained two female HDMI Y-splitters and used them to connect my Oppo BPD-83SE Blu-ray player to my UHD/4K monitor using two inexpensive, 6’ lengths of 4K HDMI cable from CZoom.
The resultant Blu-ray DVD video presentation yielded improved resolution and enhanced color contrasts with this configuration. The change in video quality was like going from 2K to something much higher than 2K (2K+). I don’t know if audio quality improved, as I haven’t connected my monitor to external speakers, home audio or video system. I’ll see whether the paralleled HDMI cable connection improves video quality from an UHD/4K player with an UHD/4K Blue-ray DVD.
This connection is analogous to the Schroeder Method of IC placement, as discussed below:

https://forum.audiogon.com/discussions/doug-schroeder-method-double-ic
The possibility that it worked at all in the HDMI context was surprising. And I’m using very inexpensive parts for this evaluation. CZoom 4K HDMI cables cost ~$15 per cable from Amazon and the HDMI Y-splitters ran ~$8 per splitter from eBay. One wonders whether significant improvements can be wrought with better quality components or an integrated dual HDMI assembly.
I would be interested in learning from others who try this technique.

I don’t. So the impact could be much greater. I searched the Forum threads for recommendations about HDMI cables. Landed on this one: https://forum.audiogon.com/discussions/one-of-the-best-hdmi-cable?page=2 Many posts by my old buddy, Geoff, who recommended AQ Carbon HDMI cables. Directional and (more) expensive. Might be my next test. |
I was initially confused after I installed the splitter configuration and turned on the DVD player: it seemed to pause for some time before presenting video images. I am not sure whether it was user/operator error or something with the newly inserted cables. Everything resolved in short order, however. @taras22: makes sense that bandwidth would be in play in both instances. @teo_audio: by "receiver chips" are you referring to monitor hardware or biological (eye/brain) hardware? |
