Feature: Resolution Selection

Scenario: Set to Kano's preferred resolution
Given Kano's list of preferred resolutions (defined below)
When I turn on the screen
Then the OS detects the screen's preferred mode (CEA or DMT)
And the OS detects the screen's preferred aspect ratio
And the OS loads a list of Kano's preferred resolutions for that configuration
And the OS selects the preferred resolution from that list which the screen supports
And the OS outputs an HDMI signal with that HDMI mode and resolution

Scenario: Set to Kano's preferred resolution for 16:9 screens
Given a screen's aspect ratio is 16:9
When the OS is searching for Kano's preferred resolutions in the screen's EDID list
Then it looks for 1366 x 768px
And then it looks for 1360 x 768px
And then it looks for 1280 x 720px

Scenario: Set to Kano's preferred resolution for 16:10 screens
Given a screen's aspect ratio is 16:10
When the OS is searching for Kano's preferred resolutions in the screen's EDID list
Then it looks for 1280 x 800px
And then it looks for 1440 x 900px

Scenario: Set to Kano's preferred resolution for 4:3 screens
Given a screen's aspect ratio is 4:3
When the OS is searching for Kano's preferred resolutions in the screen's EDID list
Then it looks for 1280 x 960px
And then it looks for 1024 x 768px

Scenario: Turn on a CEA screen with a supported resolution
Given I have a CEA screen
And My screen supports one of Kano's preferred CEA resolutions
When I turn on my kit
Then I want the OS to output HDMI signal in CEA mode
And I want that resolution to be the best possible resolution (using Kano's CEA preference list)
And I want sound to work
And I don't want the OS to reboot

Scenario: Turn on a DMT screen with a supported resolution
Given I have a DMT screen
And My screen supports one of Kano's preferred DMT resolutions
When I turn on my kit
Then I want the OS to output HDMI signal in DMT mode
And I want that resolution to be the best possible resolution (using Kano's DMT preference list)
And I want sound to work
And I don't want the OS to reboot

Scenario: Turn on a screen without a supported resolution
Given My screen doesn't support one of Kano's preferred resolutions
When I turn on my kit
Then I want the OS to output an HDMI signal with my screen's preferred resolution and mode
And I want sound to work
And I don't want the OS to reboot

Scenario: Turn on a screen without EDID information
Given My screen doesn't send the OS any EDID information
When I turn on my kit
Then I want the OS to output Kano's preferred resolution: 1280x800
And I want sound to work
And I don't want the OS to reboot
