When inside a CloudApps Classroom streaming session, the resolution and Dots Per Inch (DPI) will be adjusted to match your local device configuration. This feature has some limitations and will depend on your local device, network capabilities, and class instance type.
Some displays use DPI scaling to make text and other graphics elements appear larger on high resolution configurations. On modern high performance laptops and Chromebooks, it's common to see very high resolutions with relatively small screens (13-15"). Without DPI scaling, text would appear very small and be hard to read. DPI scaling accommodates for this by making things appear larger and sharper.
In this article, we'll review:
Sessions with a GPU
Sessions with applications that require graphics intensive workloads like 3D modeling and video editing will be created with a powerful GPU capable of high resolution streaming to your browser.
When inside a session with a GPU, the maximum supported resolution is 4096×2160 or typically known as 4K.
The streaming session will attempt to match the remote resolution to the size of the window and DPI to your local device settings up to the 4K supported resolution.
In some cases, the remote resolution cannot be matched with the local device and you may see letterboxing on the streaming window or slightly blurry text. The best way to match the resolutions is to enable the Fullscreen feature, available from the side bar within the streaming session.
The network bandwidth and latency is affected by the remote resolution. Higher resolutions require more bandwidth and can introduce latency and packet loss on slower connections. A dedicated hard wired ethernet is preferred to Wi-Fi when you want to stream at higher resolutions.
The local device must also be capable of decoding high resolution video streams to guarantee a good experience. Setting your local device to an ideal resolution like 1080p, 1440p, or 2K is suitable in most cases.
Sessions without a GPU
Sessions without graphics intensive applications do not require a GPU and have more limited resolution and DPI scaling capabilities.
The streaming session in cases where a GPU is not present is limited to 1920x1080, commonly known as 1080p.
If your local display device is not set to 1080p, the streaming session will be scaled locally to fit within the browser window. This local scaling can make text blurry or hard to read depending on the window size so using the session in Fullscreen or a window approximately 1920x1080 pixels in size is recommended.
