Monitor Scaler Color Depth Bandwidth: 8-Bit vs 10-Bit RGB Full at High Refresh Rates: Historical Paradigm Evolution and Next-Gen Architectural Projections

[Lily Collins]

Everyone keeps throwing around “10-bit” as some holy grail, but I want real field data from people actually running high-refresh panels.

Historically, the 8-bit vs 10-bit conversation at high refresh rates was purely a bandwidth problem, and the math still bites people today. Uncompressed RGB needs resolution × refresh × 24 bits (8-bit) or 30 bits (10-bit), plus blanking overhead. So a 2560×1440 panel pushing 240Hz at 10-bit demands roughly 21 Gbps of clean payload, which blows past HDMI 2.0 and even strains DisplayPort 1.2, but sits comfortably under DP 1.4’s 32.4 Gbps ceiling—if you’re still running uncompressed. That’s exactly where DSC (Display Stream Compression 1.
