RGB bias lighting with HDMI passthru for ultrawide monitor

I’m looking into bias lighting for behind my monitor. I would prefer a device that has HDMI passthru since I plug in a few different devices (laptop, Nintendo Switch, etc.). The monitor is 2560×1080. I really don’t like the idea of camera-based bias lighting.

I found this company which looks pretty good, but I don’t know if their “HD” device works with that aspect ratio/resolution. Their support contact also doesn’t seem to like replying (both the form and email).

To summarize:

• RGB Bias lighting kit
• HDMI passthru
• support for 2560×1080 resolution
