Hi,
I'm looking to purchase a 7" display with the new Eve4 BT817 controller. I am migrating an existing application which uses a 5" display which has square pixels. From reading 7" TFT datasheets I see that pretty much all of them have non-square pixels. For example the 7" 1024x600 Riverdi RVT70HSBFWN00 has a pixel size of 0.1506 (width) × 0.1432 (height).
The main reason why I want this is to display round circles, not ellipses, it also makes any math for coordinates easier.
I've searched the various datasheets but not finding much in the way of how to use Horizontal Scanout Filter. Even how its actually set (see
https://brtchip.com/wp-content/uploads/Support/Documentation/Datasheets/ICs/EVE/DS_BT817_8.pdf)
If I were to keep 1024 x 600 and set HSF to get square pixels, would I then see an unused region on the right hand edge of the display? If so, could I then increase the resolution to (for example) 1060 x 600 to use the entire width of the display?
Is there an example of this being used I could look at?
As an aside does the Eve Screen Builder / Design software (or any other similar tools) take HSF into consideration?
Many thanks
Toby
