Resolution and refresh rate

The device decides. When it connects, the app tells the computer the size and refresh rate of its own screen, and the computer’s PixelBridge display follows. You set your preferences in the Android app.

In the app: Settings › Display

Setting	Options	Default
Resolution	Auto (best latency) · Native (sharpest) · fixed sizes 1080p, 1440p, 4K where the screen has room	Auto
Refresh rate	Auto (the screen’s top rate) or a specific rate the screen supports	Auto

• Auto streams a little below the screen’s full sharpness to keep the lag down.
• Native uses every pixel of the device’s screen. Pick it for detailed artwork or small text.
• A fixed size never goes above what the device’s screen can show.

Streaming quality

When the computer supports it, the app also shows Streaming quality:

Setting	Range	Default
Speed or quality	Performance · Favour speed · Balanced · Favour quality · Quality	Favour quality
Frame-rate cap	30 to 120 fps	60 fps
Bitrate	5 to 60 Mbps	50 Mbps

The computer applies these, and it serves every connected device from one encoder, so the most demanding request wins. To get 120 fps on a 120 Hz tablet, raise the Frame-rate cap to 120. On Windows, tray › Force 120 Hz also asks for 120 Hz on the PixelBridge display.

On the computer

• Windows has no resolution setting of its own: the tablet decides, and Match the tablet’s resolution (on by default, Settings › Display) makes the PixelBridge display follow it.
• Mac has an Opening resolution (1280 × 720, 1920 × 1080, 2560 × 1440 or 3840 × 2160; default 1920 × 1080) and a Frame rate (30, 60 or 120 fps; default 60) in Settings › Display. They are used only until a device announces its own screen, and apply the next time serving starts.

If the picture lags or looks soft

• Lag: set Resolution to Auto, use the cable, or close busy apps on the computer.
• Soft picture: set Resolution to Native, or move Speed or quality toward Quality.
• Windows PC with AMD graphics only: PixelBridge uses a software encoder there, which limits the picture to about 720p. NVIDIA and Intel graphics don’t have this limit.
