Netflix Diagnostics & Stream manager screens on Fire TV
With USB keyboard connected use these keystroke combinations:
CTL + shift + alt + D (Diagnostics - A/V stats, incl detailed stream info incl bitrates)
CTL + shift + alt + S ('Stream manager control panel - options to change video bitrate and CDN)
These key combinations also work on the Windows 8/Silverlight Netflix player. The main differences being (i) the menu layout is different (ii) the Fire TV's Settings screen lists the top 5800kbps video bitrate which I haven't seen as an option on the Silverlight one, and (iii) on the Fire TV selecting the 'Override' (OK/Apply) dialogue button to apply a rate, once selected, is proving challenging dammit.
Via the debug screen I've observed that Netflix on my Fire TV generally stays around 720 / 3000kbps, even though I have a stable 15mbps+ connection.
So the option to force the Fire TV to select a higher Netflix bitrate than the conservative one it seems to be selecting for me - 1080p/5800kps in particular - has appeal. Appreciate that this might mean buffering pauses sometimes, but you don't know till you try, right? Which brings me to...
On this screen, use the Tab keyboard key to tab between panels then PageUp / down keys to cycle between options.
I got as far as succesfully selecting 5800kbps video bitrate and tabbing to highlight the 'override' (ok/execute) on-screen button but I can't find a keyboard key or combo that will 'press' this. Eg. Pressing enter/return merely toggles the underlying video between pause & play. Most keys do nothing at all. Others kick you out of the vid. Connecting a mouse brings up a circle 'pointer' but clicking with it via the left or right mouse buttons on the 'override' dialogue box does nothing. Maybe a combo of keyboard and mouse keys would work but I can't try both at once yet.
If anyone could solve this final step I'd be much obliged.
