Portable Monitor and Link Card

The Portable Monitor is a handheld screen. It streams the widget output of up to 8 computers without placing any monitor blocks — useful for drones, planes, or just checking your base from your inventory.

Crafting

Link Card — one row: paper, copper, redstone.

Portable Monitor — a shaped recipe: iron in the four corners, glass in the middle column, redstone left and right of the glass, link card on top.

Linking computers

• Right-click a computer with the Portable Monitor to add it as a channel. Right-click more computers to add more channels (up to 8; the same computer is never stored twice).
• Shift-right-click a computer to remove that computer from the channel list again.
• Shift-right-click in the air to clear all channels.

The item glows once it stores at least one channel, and its tooltip shows the linked position.

Using the screen

Right-click in the air to open the display. It shows the widgets of the active channel exactly like a wall monitor would — buttons, sliders, and text inputs are clickable.

• Click a channel tab (or press arrow left/right) to switch computers.
• Right-click a channel tab to remove that channel.
• ESC closes the screen; the game keeps running.

If the screen says no signal, the linked computer is probably not running a graph that feeds a Monitor node — see Monitors.

Same widgets, smaller screen

The portable canvas is 256×144 pixels with 6 rows, while a wall monitor starts at 64×64 pixels per block. All 12 widget types work on both.

Link Cards

A Link Card stores a reference to one computer:

• Right-click a computer to bind the card to it (the card glows and shows the position).
• Shift-right-click in the air to clear the binding.

Link cards have two uses:

1. Copy a link: hold a bound card in your offhand and shift-right-click the air while holding the Portable Monitor — the monitor replaces all its channels with just this one computer.
2. Authorization: anyone carrying a bound Link Card (in the inventory or offhand) can view and click the linked computer's displays, even from far away — there is no distance limit. This is what keeps drones and planes usable.

Computed Glasses use the same trick: they mirror your first bound card as a wearable HUD.
