Option to prevent dGPU from disabling in Eco mode (battery power) ONLY if an HDMI monitor is connected

Is your feature request related to a problem? Please describe

Currently, on ASUS laptops (like the TUF A14), when switching to battery power, G-Helper automatically switches to Eco mode (if Optimized mode is selected) and disables the discrete NVIDIA GPU.
This causes "annoyances" when using an external monitor connected to the HDMI output, which is driven exclusively by the dGPU, resulting in the loss of the external display signal.

Describe the solution you'd like

Add a configurable option in G-Helper that:

• Detect if an external monitor is used or connected via HDMI
• If enabled, prevent automatic disabling of dGPU in Eco mode when on battery power only if an HDMI monitor is connected
• If this option is disabled or unchecked, the current behavior (disabling dGPU in Eco mode when on battery power) remains unchanged
• When the option is enabled but no HDMI monitor is connected, the dGPU should still be disabled as usual in Eco mode on battery power
• Additionally, when this option is enabled and an HDMI monitor is connected, prevent the system from going into sleep mode on battery power when the lid results closed (as already happens with the "clamshell" mode option in AC power)

This feature would allow users to keep external displays active while on battery power (e.g. off the AC power supply for a few seconds/minutes only), without sacrificing the default power saving benefits of Eco mode when no external monitor is connected.

Thanks for considering this option!

@raksati hello, I was answering this couple of times already.

I don't know any reliable way to detect if external monitor is connected via HDMI specifically (as it could be connected via left USB-C to iGPU as well).

Honestly, if you use external monitor on battery, why don't you just set Standard mode to make sure that GPU is always on ? Switching between modes in G-Helper is extremely easy :)

Hello,

I resolved with an external Powershell script that use G-Helper hotkey:

Add-Type -AssemblyName System.Windows.Forms
function Get-PowerStatus {
$status = Get-CimInstance -Namespace root\wmi -ClassName BatteryStatus
return ($status.PowerOnline -eq $true)
}
function Is-ExternalMonitorConnected {
# Recupera monitor connessi, considera quelli con VideoOutputTechnology = 5 (HDMI)
$external = Get-CimInstance -Namespace root\wmi -ClassName WmiMonitorConnectionParams | Where-Object { $_.VideoOutputTechnology -eq 5 }
if ($external) {
return $true
}
return $false
}
$lastMode = ""
while ($true) {
$onAC = Get-PowerStatus
$hasExternalMonitor = Is-ExternalMonitorConnected
$newMode = ""
if (-not $onAC) {
if ($hasExternalMonitor) {
$newMode = "STANDARD"
}
else {
$newMode = "ECO"
}
}
else {
$newMode = "STANDARD"
}
if ($newMode -ne $lastMode) {
switch ($newMode) {
"STANDARD" { [System.Windows.Forms.SendKeys]::SendWait("^+%{F15}") }
"ECO" { [System.Windows.Forms.SendKeys]::SendWait("^+%{F14}") }
}
Write-Host "Modalità attiva: $newMode"
$lastMode = $newMode
}
Start-Sleep -Seconds 5
}
