Lower refresh rate from LCD, is it possible to increase it?

What I mean is when I have the FPZ connected to my TV via HDMI the game play is smooth w/o stuttering on the TV, the FPZ stutters. quick example is screen transitions in Super Metroid, on the FPZ they animate as if I have frame skip set to 1 and on the TV it's set to 0. TBH I can't even get the audio to output via HDMI. I'm using the default emulators from the SD image. Every emulator runs like that even the Retropie menu isn't as smooth as it is on my TV.
