[AccessD] Screen Resolution

[James Button]

My take on resolution and screen size -

Ideally the screen should be at a sufficient distance for you to be able to see all of the screen with one eye and not moving  your head or eye.
  - or you will be continually turning your head.
At 4K the screen will probably allow text to be too small to read easily.
but you can set the video driver to run a 4K screen at HD.
Using 4K resolution may make it OK to have multiple App displays on the screen at one time
 so you can concentrate on whichever is appropriate for a session. Having the others open for occasional reference
 - or for spreadsheets, and tabular data that would have had you very frequently scrolling the screen left and right.
Also allows 2 up views of pictorial mode pages.

But the selected resolution of the signal going to the display should not be set to higher than the video resolution you are using within the OS screen setting
just wastes CPU, memory (& paging I/O( as well as power 0- and can actually give a poorer display image than having the setting being a submultiple of the screen pixel count (width and height)
as in put a 1920x1080 set of pixels onto a HD ready 1,280 x 720  screen means the video board has to have space and CPU to generate the image, 
and then the screen electronics have to convert it by merging pixels to get the actual physical cell count - 
And a blue line next to a red one on the image gets shown as a single ( purple ?) one on the display,
OK - a red one between 2 blues  may be shown as just blue as there are 8 blues and 8 reds to be split over a 3x 3 block of cells  !
so - best to have the video board output match the cells on the display !
  
Also worth remembering that many 'office work' on the motherboard video controllers will acquire main memory RAM if there is not enough on the video system to run the displays at your selected resolution.
