Scaling
Scaling changes video resolution so equipment with different capabilities can coexist in the same HDMI system.
Scaling means making the picture bigger or smaller in pixels, for example from 4K to 1080p or back.
It lets a 4K player work with an older Full HD screen, and the other way round.
Like resizing a photo, the content stays the same, only the number of pixels changes.
Can the HDfury Vertex upscale and downscale?
YESYes. It scales between 1080p and 4K at 24/25/30/50/60 Hz, per output: TOP (TX1) is the downscale port and BOTTOM (TX0) is upscaled when possible. The frame rate stays the same.
How to use it with the Vertex:
- Choose a mode with the SCALE slide switch: No Scaling/Passthru, Custom Scaling/GUI or Auto Scaling (p.12).
- Auto Scaling: both outputs sense the connected display and convert to what it can show (p.14).
- Custom Scaling: in the GUI SCALER section set resolution, colour space and deep colour per output (p.30).
- Tick NO UPSCALING if your display should do the upscaling (p.31); RS232: #set scale auto/custom/none (p.49).
What it is
Scaling changes video resolution so equipment with different capabilities can coexist in the same HDMI system.
Why it matters
HDMI behaviour is determined by the complete signal chain. Vertex exposes and manages these technical layers so mixed sources, displays, projectors and AV processors can be configured more deliberately instead of relying only on automatic handshakes.
Common questions
Can the Vertex send 4K to my TV and 1080p to my projector at the same time?
Yes. In Auto Scaling mode both outputs auto-sense the connected display, and the TOP output can down-convert, for example to 1080p60 (p.14).
Will scaling make the picture worse?
Downscaling loses detail the smaller screen cannot show anyway. For a display that supports the input format, No Scaling/Passthru passes the signal untouched (p.12).
Should I turn scaling off for Dolby Vision?
Yes, use No Scaling/Passthru. TV-led Dolby Vision travels in an RGB 8-bit container and changing the format can break it (p.12, p.113).
