Techniques are disclosed to select display settings for a display device. Device capabilities may be read from a display device and a determination made whether the device capabilities support other display formats than are read from the display, for example, a high dynamic range (HDR) format or a high resolution format. When the device capabilities do not include an format supported by a video source, video may be driven from the video source to the display device in the format and, if confirmation is received that the display device displays the driven video, settings may be stored for the display device identifying the format as a one supported by the display device. Additionally, interconnect may be tested by estimating noise levels generated by the interconnect to a network connection and/or by estimating network throughput both when video is driven over the interconnect and when it is not. Display formats may be selected for the device based on a maximum data rate of a network connection that can be maintained while the interconnect carries video.
