Free tool · Portrait Displays G1

Set the IP on a Portrait Displays G1 in 60 seconds.

The G1 reads its network settings from a file named net_config.ini on a USB stick. This tool builds that file for you, no IP coding guesswork. Fill in the form, download the file, drop it on the USB, plug into the G1.

Configure as many units as you like. Each one ships in its own folder inside a single ZIP, so you never confuse one G1's config for another. Runs entirely in your browser: nothing is uploaded anywhere.

Introducing the G1 Pattern Generator

1Identify the unit
Used as the folder name in the ZIP. Pick a pattern from the dropdown or type your own.
Defaults to portrait-g1 if blank. Changing it reboots the G1.
2How will it connect?
Wired is the default and most reliable. Switch to Wi-Fi only if no Ethernet is available.
DHCP works if your network hands out IPs automatically. Static is required for fixed addresses.
3Static IP settings
Skip the rest? Click Auto-fill and we'll set the gateway to x.x.x.1 (your subnet's .1), primary DNS to the gateway, and secondary DNS to 8.8.8.8.

Batch — units ready to download

No units yet. Fill in the form above and click Add to batch.
Preset = a small .json file that remembers every unit in the batch (name, network, IP, Wi-Fi, etc.). Save it to archive a job, share with a colleague, or come back later to regenerate the ZIP. Note: Wi-Fi passwords are stored in plain text, treat the preset file like any other config file.

What to do with the file

  1. Format the USB stick to exFAT. The G1 reads exFAT only. Windows: right-click the drive → Format… → File system: exFAT → Start. macOS: open Disk Utility → select the USB → Erase → Format: ExFAT.
  2. Extract the ZIP you downloaded. You'll see one folder per unit.
  3. Copy the net_config.ini from one unit's folder onto the root of the USB stick. Only that one file should be on the drive, nothing else, no folder.
  4. Connect the G1 to a display via HDMI (the network stack only activates when a display is present), and connect Ethernet or place it within Wi-Fi range.
  5. Insert the USB into the G1's USB port. The status light goes solid while the G1 reads the config.
  6. Wait for the light to return to blue. Then it's safe to remove the USB. The G1's new IP address is shown on the connected HDMI display.
  7. Configuring another G1? Repeat steps 3–6 with the next folder's net_config.ini. Same USB stick is fine, just overwrite the file each time.

Common pitfalls

Nothing happened when I plugged in the USB
  • The drive isn't formatted as exFAT. FAT32 and NTFS won't be read.
  • The file isn't named exactly net_config.ini (lowercase, no extra extension like .ini.txt).
  • The file is in a folder on the USB instead of at the root.
  • Other files are on the USB. Per Portrait, the INI must be the only file in the directory.
  • No HDMI display is connected, the G1's network stack stays inactive without one.
The Wi-Fi password isn't being accepted
  • The G1 supports WPA2 only. WPA3-only networks won't connect.
  • Firmware 1.00.025 has a known bug with the $ character in passwords. If your password contains $, change the network password or use a guest SSID.
  • The G1's Wi-Fi radio is 2.4 GHz, 802.11 b/g/n only. A 5 GHz–only SSID won't be visible.
The G1 took the IP but I can't reach it
  • Confirm the IP shown on the HDMI display matches what you intended.
  • Make sure your computer is on the same subnet (or routed to it).
  • The G1 listens on port 2101. If you're firewalled, allow that port.
  • If you set a static IP, double-check the gateway is in the same subnet as the IP.
How do I reset network settings?

Generate a fresh INI with the values you want (or with DHCP selected to fall back to automatic) and apply it the same way. The last config wins.
