Change the HDMI output resolution in a RK3188 android stick

Hello all,

Im trying to use a RK3188 android player (model Q7S, Android 4.4) to drive a 3d kiosk but the 3d display has a pretty low resolution (800x600) that is incompatible with the available outputs (they have a very similar 720×576 resolution).

There's any way to change it? Maybe a custom kernel that would work or a way to modify the stock kernel.

The device is already rooted with a custom recovery installed.

Best Regards,
Igor

Cx919ii (j22) rk3188 CWM

Hi folks I asked this over at freaktab but no answer....
I have a cx919ii and its running its original 4.2 JB now for a over year ,its rooted, and even has a 1 TB USB drive (thanx Stickmount). I want to use cwm for my recovery but I have not found one specially for my unit. What I have found is a generic rk version that depends on the existing kernel IMG and doesnt write /kernel.
Anything out there that will boot even if I get the wrong kernel while flashing a ROM and also has adb (also just in case) help me out...Google hasn't found me the answer

Joying Rk3188 Head unit Questions

I've tried searching and couldn't find any concrete answers (probably tapatalks fault) to the following problems. What is the voltage on the audio preouts(RCA's)? I just installed the JY version yesterday and noticed my volume has greatly decreased from the OEM unit with an active Line out converter. I'm thinking its the preouts voltage. The second question has anyone been successful at getting torque or Carista to work? I have a BT ELM 327 adapter that I've had for years and it has worked with all other android with out a problem. It does not even show up in Bluetooth devices. The third question is on cars with a can-bus system. I have this installed in as 2011 VW CC, is there anyway to get song information to show up with a music app other than the stock music player? I'm not too fond of the JY music interface. I'm currently running Malaysk's ROM and darkleo's MCU v2.59
