I have an UI5-based app (1.66+), which works correctly, but there are huge empty spaces on the left and right sides of the screen (aka letterboxing is on):

I want to disable letterboxing to use the entire screen space.

I tried the following approaches so far:

To use "fullWidth": true in sap.ui section of manifest.json
To add desktop-related classes to the HTML-tag in index.html:

<html class="sap-desktop sapUiMedia-Std-Desktop sapUiMedia-StdExt-LargeDesktop">

To add appWidthLimited: false to index.html:

<script>
    sap.ui.getCore().attachInit(function () {
        new sap.m.Shell({
            app: new sap.ui.core.ComponentContainer({
                height: "100%",
                name: "APPNAME"
            }),
            appWidthLimited: false
        }).placeAt("content");
    });
</script>

Just like it is described in «How to customise Shell container in SAPUI5».

But none of them works for me.

Update:
I succeeded to solve the issue via a static XML-template — just add <Shell id="shell" appWidthLimited="false"> to the main XML-template, but now I want to understand how to implement it via JS in new sap.m.Shell(…) definition.

The starting point for code experiments is below.

index.html:

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8">
        <meta name="viewport" content="width=device-width, initial-scale=1.0">
        <title>widescreen</title>
        <script id="sap-ui-bootstrap"
            src="../../resources/sap-ui-core.js"
            data-sap-ui-theme="sap_fiori_3"
            data-sap-ui-resourceroots='{"letterboxing.widescreen": "./"}'
            data-sap-ui-compatVersion="edge"
            data-sap-ui-oninit="module:sap/ui/core/ComponentSupport"
            data-sap-ui-async="true"
            data-sap-ui-frameOptions="trusted">
        </script>
    </head>
    <body class="sapUiBody">
        <div data-sap-ui-component data-name="letterboxing.widescreen" data-id="container" data-settings='{"id" : "widescreen"}' id="content"></div>
    </body>
</html>

Component.js:

sap.ui.define([
    "sap/ui/core/UIComponent",
    "sap/ui/Device",
    "letterboxing/widescreen/model/models"
], function (UIComponent, Device, models) {
    "use strict";

    return UIComponent.extend("letterboxing.widescreen.Component", {

        metadata: {
            manifest: "json"
        },

        init: function () {
            // call the base component's init function
            UIComponent.prototype.init.apply(this, arguments);

            // enable routing
            this.getRouter().initialize();

            // set the device model
            this.setModel(models.createDeviceModel(), "device");
        }
    });
});

Ok, so there seems to be many similar questions regarding how to disable/enable letterboxing. This answer should provide a solution for each case:

Standalone

Look for the instantiation of sap.m.Shell in your project and configure appWidthLimited accordingly.

For example:

In index.html or index.js

sap.ui.require([
  "sap/m/Shell",
  "sap/ui/core/ComponentContainer",
], (Shell, ComponentContainer) => new Shell({
  appWidthLimited: false|true, // <--
  // ...
}).placeAt("content"));

In root view

<Shell xmlns="sap.m" appWidthLimited="false|true">
  <App>
    <!-- ... -->

Of course, the Shell can be configured dynamically in JS too with myShell.setAppWidthLimited(false|true).

API reference: sap.m.Shell

Only for SAP Fiori launchpad (FLP) case

The component …:

should not contain sap.m.Shell anywhere (please check the root view).
launches from FLP instead (no index.html).

Statically in manifest.json

"sap.ui": {
  "fullWidth": true|false,
  ...
},

Dynamically in runtime

sap.ui.require([ // somewhere in controller
  "sap/ushell/services/AppConfiguration"
], config => config.setApplicationFullWidth(true|false));

API reference: sap.ushell.services.AppConfiguration

According to Available OpenUI5 Versions the newest OpenUI5 version is 1.65.0. How is you app based on 1.66.0?

Setting appWidthLimited: false on the sap.m.Shell should do the work. Check out this example (plunker / github) (in the Plunker run preview in a new window)

You can achieve that removing the shell control from index.html:

sap.ui.getCore().attachInit(function () {
    sap.ui.require(["sap/ui/core/ComponentContainer"], function (ComponentContainer) {
        new ComponentContainer({
            name: "yourProject",
            async: true,
            manifest: true,
            height: "100%"

        }).placeAt("content");

    });
});

instead of this:

<script>
    sap.ui.getCore().attachInit(function () {
        new sap.m.Shell({
            app: new sap.ui.core.ComponentContainer({
                height: "100%",
                name: "APPNAME"
            }),
            appWidthLimited: false
        })
        .placeAt("content");
    });
</script>

Static implementation via XML-template:

<mvc:View controllerName="letterboxing.widescreen.controller.index" xmlns:mvc="sap.ui.core.mvc" displayBlock="true" xmlns="sap.m">
    <Shell id="shell" appWidthLimited="false">
        <App id="app">
            <pages>
                <Page id="page" title="{i18n>title}">
                    <content></content>
                </Page>
            </pages>
        </App>
    </Shell>
</mvc:View>
