Correct screen saver displayed. I really wish there was a way to display the whole thing and not get cut off on the side
I have the full width aquarium showing on my 32" TV/monitor in windowed mode under Linux as an experiment, after I came across an old comment in the forum about it some time ago. The only problem is that it has a window border and it is quite short to maintain the correct aspect ratio. From memory, the window is 1912x538.
If I recall correctly, the suggestion was to either remove window borders or create a black border and a black desktop and hide the taskbar under Windows, but I'm not sure yet how to do that under Linux.
However, the issue remains that the full width aquarium will be "letterboxed" on standard 16:9 displays and only on super-wide 32:9 displays would it potentially fill the screen.
There is another issue with the full width aquarium and that is on plasma and OLED displays, the small somewhat static image may cause image retention problems. I think it would need a scroll pixel shader or something equivalent to pan the window vertically and smoothly over time to ensure more pixels were activated on average. Unfortunately I am not knowledgeable enough about such things to competently implement, although it does not matter on my VA TV/monitor where I have been testing it out as it is not so sensitive to image retention or uneven pixel wear.
I suspect IPS LCD displays would be best for full width aquariums as they don't suffer much from image retention and their colour/brightness rendition off-axis is not as impaired, whilst their lower contrast is not really an issue with bright colours.
