Comet (GL-RM1) V1/V2 Console Guide¶
Settings¶
On the console, navigate to Settings. The settings page includes four sections:
Quick Search¶
You can quickly find the settings you want by entering keywords at the top of the Settings page.
Video¶
You can customize the video settings on the console, such as display mode, video quality, video transmission, screen orientation, and EDID.
-
Mode: Switch between Normal and Smart mode as needed. Smart mode helps reduce bandwidth consumption, especially in weak networks.
-
Latency Mode: You can choose between Lowest Latency and Smooth Display for the device. This feature was introduced in firmware v1.9.0.
What's the difference between Lowest Latency and Smooth Display?
-
Lowest Latency: Minimizes input latency to deliver snappier keyboard and mouse response.
-
Smooth Display: Optimizes visual performance to eliminate stuttering and frame loss for steady playback.
-
-
Quality: Adjust the video quality to low/medium/high/ultra-high/Lossless according to your network environment and resolution requirements.
-
Transfer: Switch the video transmission method between WebRTC, WebRTC (FEC), and Direct. Note that the Direct transfer has no sound.
What's the difference between WebRTC, WebRTC (FEC) and Direct?
-
WebRTC: Balances smooth video and stable audio for real-time remote control.
-
WebRTC (FEC): Adds forward error correction to improve connection stability under poor or unstable network conditions. When selected, it automatically repairs lost data packets by transmitting a small amount of redundant data, reducing screen flickering and lag.
-
Direct: Provides the lowest latency and lossless video quality, but does not support audio transmission.
-
-
Orientation: Adjust the console's rotation angle to 0°/90°/180°/270°.
-
EDID: Short for Extended Display Identification Data, it automatically matches the optimal display parameters.
The default setting applies to most scenarios and generally does not need to be modified. See here for details. If the screen does not refresh after EDID adjustment, restart the controlled device.
-
View: This setting, introduced in firmware v1.9.0, determines screen scaling when resizing the browser window. Available options: Adaptive, Best Picture Quality, Original Pixel.
Remote Device Settings¶
You can adjust the relevant settings of the controlled device.
-
Speaker: Control audio output from the controlled device (e.g., system sounds, video audio)
-
Microphone: Transmit local audio (e.g., your voice) from the controlling device to the remote end. It supports one-click mute, and a long-press shortcut to activate the microphone (i.e., Press To Speak).
-
Keyboard: Turn on or off the keyboard of the controlled device.
-
Bad Link Mode: i.e. Release keys immediately. Each key press is sent as a single quick press-and-release action, preventing stuck keys or unintended repeated input during remote control.
-
Show Virtual Keyboard: Show and use the virtual keyboard on the console.
-
Swap Command and Ctrl for MacOS: This feature swaps the Cmd and Ctrl keys to ensure keyboard compatibility across different operating systems.
-
Mouse: Turn on or off the mouse of the controlled device.
-
Show Local Cursor: Show the mouse of the controlling device on the screen.
-
Mouse Jiggle: The Mouse Jiggler feature simulates subtle, periodic mouse movements to prevent the computer (i.e., the controlled device) from going to sleep due to prolonged inactivity, such as during remote meetings and server management.
-
Scroll Rate: It refers to the speed at which the mouse wheel scrolls or the number of lines/units scrolled per wheel rotation, affecting how quickly content moves on the remote.
-
Scroll Direction: It determines whether scrolling the mouse wheel up/down moves content on the remote screen in the same direction (natural scrolling) or the opposite direction (traditional scrolling).
Four direction modes are available: Standard, Vertical Invert, Horizontal Invert, and Both Invert.
-
Mouse Mode: Allows switching between Absolute Mode and Relative Mode to ensure smooth and accurate cursor control in different remote control scenarios.
What's the difference between Absolute Mode and Relative Mode?
-
Relative Mode: The mouse position is calculated based on movement rather than fixed screen coordinates. You must click inside the remote window to control the mouse. The cursor is locked within the remote screen and cannot move out smoothly. This mode provides better compatibility with BIOS, old systems, and embedded devices.
-
Absolute Mode: The mouse position corresponds to exact screen coordinates. The remote cursor follows the local one smoothly and accurately, allowing seamless movement between your local screen and the remote screen. It is ideal for daily desktop control and precise operations, though a slight delay may occur due to network transmission.
In short, use Absolute for smooth daily control; use Relative for BIOS access, some older devices that do not support absolute positioning, or to avoid accidental cursor movement.
-
-
Relative Sensitivity: It is available when the Mouse Mode is Relative.
-
Primary Button: Select the left or right button as the primary click. This feature was introduced in firmware v1.9.0
System¶
You can customize the system display settings of the console, or reset the device with one click.
-
