Rk 3328 video resolution

Having a problem with my board and screen. Recently purchased a couple of inexpensive touch screens that work dandy for pi and lepotato but the resolution on renegade is too high and text just looks like dust on a 7 inch monitor. I took a look at potato xorg driver.conf and there's a lot of modes listed, but on renegade I see:

Section "Device"

                Identifier "NOGPU"

                Driver "fdev"

Endsection

And xrandr -- listmonitors output:

Failed to get size of gamma for output default

Monitors 1

0: +default 1600/423x900/238+0+0. 

I'm still learning things, but I know exactly how to brick it again 😃. 

I hope I have enough information for you and your assistance will be greatly appreciated.
