By using a Chrome browser (version 55 or later), you can use multiple monitors in HTML Access Web client to display a remote desktop window.

You can add up to one additional monitor to your primary monitor to display the current remote desktop window to which you are connected. For example, if you have three monitors, you can specify that the remote desktop window appears on only two of those monitors. Adjacent monitors must be selected for the multiple-monitor setup. The monitors can be positioned side by side or stacked vertically.

Beginning with HTML Access Web client 4. 5, the per device DPI synchronization is applied when the multiple-monitor feature is enabled. If you are using two monitors that have different DPI settings, the DPI settings on the HTML Access agent are set to the same DPI setting value used by the monitor of the client machine that was used to start the HTML Access Web client session.
