Common Features During Remote Control

After initiating remote control, members can expand the control panel through the floating arrow above the remote control screen, and adjust features such as video, audio, keyboard and mouse, clipboard, preferences, and performance monitor as needed.

Prerequisites

• The member has joined the enterprise;
• The administrator has authorized the target device for the member;
• The member has successfully initiated a remote control session;
• The current member has the corresponding feature permissions.

If a feature entry is not visible, contact the enterprise administrator to confirm role permissions.

Resolution, Refresh Rate, and Image Quality

If you need to adjust resolution, refresh rate, or image quality during a remote session, first click the floating arrow above the screen to expand the control panel, go to Video, and then configure the following settings as needed.

Resolution

Click Resolution and select a suitable resolution option as needed.

Up to 8K resolution is supported.

Refresh Rate

Click Refresh Rate and select a suitable refresh rate.

Up to 165Hz is supported.

Image Quality

Click Image Quality and select a suitable image quality option as needed.

Advanced option: Select YUV 4:4:4 Color to improve image color performance.

In AskLink Business, the available image quality upper limit may be affected by enterprise service, network route, and administrator configuration.

Full Screen, Maximize, and Display Fit

This section explains AskLink's display fit options to help you find suitable settings between clear display and convenient operation.

Display Fit Options

Through Display Fit, you can select how the remote screen fits the window. The following three modes are available:

• Scale Mode: The remote screen is proportionally filled inside the remote window and adjusts with the window size;
• Original Mode: The remote screen is displayed at its original resolution. If the remote screen resolution is larger than the local resolution, scroll bars appear;
• Auto Mode: Intelligently combines scale and original strategies.

If black borders appear, it is usually because the aspect ratios of the Controlled and Controller are different. You can adjust the resolution ratio on the Controlled.

Click the floating arrow above the remote screen to expand the control panel, select the Video settings item, and choose the desired display mode under Display Fit.

Fit Strategy in Full Screen

Click the floating arrow above the screen to expand the control panel, then click the Full Screen Mode button.

Fit Strategy When Maximized

• Auto: The remote screen proportionally fills the remote window;
• Original: The remote screen is tiled inside the remote window;
• Scale: The remote screen proportionally fills the remote window.

Click the Maximize button above the window or double-click the taskbar to maximize the window.

The default scale mode on macOS cannot be adjusted.

Remote Audio

Remote audio can transmit sound from the Controlled device to the Controller, making it easier to receive system notifications, meetings, media playback, and other audio content in sync. You can also select the capture device of the Controlled as needed to meet different usage scenarios.

Turn Remote Audio On or Off

1. Click the floating arrow above the remote screen to expand the control panel, then select the Audio settings item;
2. Turn the Remote Audio option on or off to enable or disable remote audio.

Through the Shortcut Bar

1. Click the floating arrow above the remote screen to expand the control panel;
2. Click the Audio Button to enable or disable audio transmission.

Background Audio

On desktop, background audio lets audio continue playing after switching session tabs or minimizing the window.

1. Click the floating arrow above the remote screen to expand the control panel, then select the Audio settings item;
2. Turn the Background Audio option on or off to enable or disable background audio.

On mobile devices, after Background Audio is enabled, remote audio can continue playing even after switching to another app.

2. At the target location, use the shortcut Ctrl + V, or right-click and select Paste.

If you do not need real-time clipboard content sync, keep Clipboard Sync in Preferences on the control panel turned off.

When macOS is used as the Controller, two-way text sync is supported, while files only support sync from the Controller to the Controlled.

Virtual Display

During remote control, you can create one or more virtual screens to expand the workspace.

Create a Virtual Display

1. Click the floating arrow above the screen to expand the control panel, then select Video;
2. Click Create Virtual Display to complete the operation.

Enable Disable Special Pointer Style in the Preferences tab.

Privacy Screen and Lock Screen When Remote Control Ends

• After Privacy Screen is enabled, the physical screen of the Controlled device hides displayed content during remote control;
• After Lock Screen When Remote Control Ends is enabled, the Controlled is automatically locked when the session ends.

Enable Privacy Screen or Lock Screen When Remote Control Ends in the Preferences tab.

Encoding Options

HEVC-preferred encoding and GPU acceleration options for the Controller and Controlled are provided. You can choose according to device performance.

Enable the options under Encoding Options in the Preferences tab.

Performance Monitor

The Performance Monitor is used to quickly understand the current remote connection status and help determine the current network status and device performance.

Basic Information Area

You can view the basic status of the current connection.

Controlled Screen Capture Method

• Windows: DXGI (Windows 8 and later) / GDI (Windows 7);
• macOS: Metal;
• Linux: X11;
• Android: MediaProjection;
• iOS: ReplayKit.

Encoding Method

Example: H.264 / HEVC (H.265).

Color

Example: 4:2:0 / 4:4:4.

Network Information Area

You can view the service level and network information of the current connection.

Route Level

• Free Route: Image quality up to 4K 30 FPS 8 Mbps; File Transfer 2 Mbps; no acceleration capability;
• High-Speed Route: Image quality up to 4K 60 FPS 16 Mbps; File Transfer 4 Mbps; when an unstable connection is detected, AskLink acceleration nodes are used automatically;
• Dedicated Route: Image quality up to 4K 165 FPS 24 Mbps; File Transfer 8 Mbps; when an unstable connection is detected, AskLink acceleration nodes are used automatically;

Performance Area

Traffic

Indicates the current remote connection data status, measured in KB/s.

Latency

Indicates the time from your operation to the other device's response, measured in ms.

Packet Loss Rate

Indicates the percentage of packets that fail to arrive successfully during network transmission out of the total sent packets. Packet loss may cause operation commands to be lost, or the screen to stutter or skip frames.

Effective Frame Rate

AskLink uses a dynamic frame rate strategy and only captures and transmits as needed when the screen changes. Therefore, the real-time frame rate of the Controlled device changes dynamically with screen content.

Other Term Explanations

HEVC / H.264

• H.264 (AVC): Strong versatility, best compatibility, balanced image quality and size;
• HEVC (H.265): Higher compression efficiency, lower bandwidth usage, and higher hardware requirements.

4:2:0 / 4:4:4

• 4:2:0: Default or common choice for video, saving bandwidth;
• 4:4:4: More precise color edges and clearer image, with higher hardware requirements.

MAX / MIN / CUR

• MAX: Maximum value in the last 30 seconds;
• MIN: Minimum value in the last 30 seconds;
• CUR: Real-time value.

How to Enable Performance Monitor

Enable by Default

1. Go to My in the AskLink Business Controller;
2. Click Other;
3. Enable the Performance Monitor option.

Enable Only When Needed

1. Enable Performance Monitor in Other;
2. You can also open it through the shortcut bar icon.

Notes

• If a feature entry is not visible, it usually means the administrator has not enabled the corresponding permission, or the current device or system does not support the feature;
• High resolution, high refresh rate, high image quality, remote audio, and screen extension increase network bandwidth and device performance consumption;
• Features such as driver-level keyboard and mouse, privacy screen, and virtual display may require the Controlled device to have the corresponding system permissions.
