      I have Raspberry 3 connected to JVC monitor with composite cable.
      sdtv_mode= 16 active.

      ES screen picture is blurry, almost unable to read.
      When starting MAME games everything is fine. Any ideas, what to try to improve ES picture quality?

        @mjh Have you tried editing the recalbox.conf file?
        Try to edit the recalbox.conf, line:
        ;system.es.videomode=CEA 4 HDMI
        Delete the semicolon from the beginning, getting:
        system.es.videomode=CEA 4 HDMI

        There is not only the "CEA 4 HDMI" option, there are many other modes that you can test and find out which fits best in the screen that you use.

        You must follow the format: "DMT 4 HDMI" or "CEA 4 HDMI"

        CEA modes are intended for TV, they include plenty of interlaced and progressive modes, usually with 25/50 / 100Hz (PAL) or 30/60 / 120Hz (NTSC) frame rates and TV resolutions of 288/480/576/720/1080 scan lines. DMT modes are intended for computer monitors, therefore there are none of the interlaced modes, the resolutions are 640/720/800/1024/1280 and the frame rates are compatible with the computer monitors, something like 60/70/75/80 / 85 / 120Hz.

        In this link you will find the detailed list of videomode:

          I understand information like this:
          CEA & DMT modes mentioned on the list behind Your link are for HDMI only?

          My JVC monitor is connected using composite cable, so HDMI setting are not affecting to picture? Or am I understanding something wrongly?

            @mjh Sorry! You're right, so change:
            system.es.videomode=default
            Change too:
            global.videomode=default
