Two different version: GSL1680E and GSL1680F

We might have a problem because there is two different version of the chip see:

What's the problem here? Is it relative to the resolution? One is 800x480, another is 480x272?

Isn't it just using a conversion factor?

800/480: 1.667
480/272: 1.765

P.S.: I noticed that the example codes in the mentioned links have a definition of SCREEN_MAX_X and SCREEN_MAX_Y, but apparently they are not used anywhere.

I believe the resolution is configured directly in the firmware.

So I sent an email now to 'Silead Inc.', they still have an active website, "www.sileadinc.com", it's in chinese, but with Google Translate I was able to find the contact page.

Not sure there is a problem to start with. It's just the I couldn't test both variant to make sure the driver work for both of them
