LCDSirPlus release packages are unsigned. Verify the supplied SHA-256 checksum before running or extracting a download.
LCDSirPlus is a Windows dashboard for the Logitech G13. It shows system, game, device, network, and Discord voice information on the G13 LCD or an on-screen preview. The preview works without a G13.
- Windows 11 x64
- A Logitech G13 for the physical LCD and buttons; optional for preview use
- Logitech Gaming Software for the recommended G13 connection
- PresentMon for FPS; release packages include the approved executable
- HWiNFO or LibreHardwareMonitor for CPU temperature; neither is bundled
- Discord Desktop and your own Discord application for voice names
Verify a release package's SHA-256 checksum before running it. The instruction manual contains the complete verification and installation steps.
For an installed copy, open LCDSirPlus from the Start Menu. The installer also adds shortcuts to the instruction manual and security guide.
For a portable copy, extract the ZIP, open its folder in Terminal, and run:
.\LCDSirPlus.exe --previewThe tray icon controls the preview. Clicking the preview does not take keyboard focus from a game or other active app.
Installed settings are stored in:
%LOCALAPPDATA%\LCDSirPlus\Config\lcdsirplus.txt
Portable settings are in lcdsirplus.txt beside LCDSirPlus.exe. Valid saved
changes apply automatically; invalid changes are rejected without replacing the
last valid settings.
Use the instruction manual for setup and troubleshooting, the configuration reference for every setting, and the button option reference for all 53 LCD choices.
- Never put a Discord client secret in settings, command arguments, logs, screenshots, issues, or chat. Paste it only into the manual's masked prompt.
- PresentMon can display a selected program filename and FPS. Set
presentmon_enabled 0if that exposure is unacceptable.
Safe mode disables optional dashboard data sources, network probes, startup changes, and destructive actions while keeping basic local readings and the preview available:
.\LCDSirPlus.exe --safe-modeExplicit Discord authorization and credential-removal commands remain available in safe mode. See the security guide before sharing diagnostics or changing hardware-related services.
Exit LCDSirPlus before updating. Run a newer installer with the same scope, or
replace the files in a portable folder. Settings under %LOCALAPPDATA% are kept
when an installed copy is removed; the manual explains how to remove them.
