Video performance
Image quality: Clean 4K scaling with accurate edge detail and minimal aliasing at moderate scaling ratios. Colors are generally neutral; built-in color controls allow useful fine-tuning.
Scaling algorithm: Good balance between sharpness and artifact suppression. Very large upscales or extreme downscales can show minor ringing or softness compared with high-end broadcast scalers.
Frame rate handling: Stable conversion across common frame rates (24/25/30/50/60). Smooth pulldown and deinterlacing for interlaced sources on supported models.
HDR: Basic HDR pass-through supported on many units; comprehensive HDR tone-mapping may be limited or require firmware/configuration.
— I can do that. But I need to confirm: vec550 4k upd
PoE (Power over Ethernet): Simplifies installation by receiving power via the network cable.
IR & RS-232 Passthrough: Allows remote control of source devices.
Scalability: Capable of 1-to-many or many-to-many matrix switching.
Q: Can I downgrade to a previous firmware version?
A: Downgrading is possible but not recommended unless you are experiencing severe bugs on the new version. The process requires a special "force downgrade" package from technical support. Because it is a musical instrument, it does
Strengths
