already checked. there is no such setting.

i googled, and found that other peoples are experiencing the same problem with their 2K android player



either
- the apps developers update their app layouts to support 2K
- the brand releases a firmware update to address this issue (since mine is brandless, FML)
- or i need to tweak down the resolution by myself (which defeat the purpose of buying 2K screen)

IMO, until 2K become a mainstream resolution for car android player, avoid it at all costs. unless u dont mind this one problem.

UPDATE:
car link works great. it seems like it doesnt have issue with the resolution. gmaps displayed properly. but you need to reconnect everytime you minimize/switch to other app, which is a hassle and major turn off.

UPDATE 2:
i found the culprit for the gmap UI problem. the default home screen has a gmap widget. i just simply remove the gmap widget, and voilaaaa. the UI become much much better, like in phone & tablet. other app like youtube and play store still have small UI.
