How to change resolution in the recalbox 4.0?



  • Hi,

    The recalbox is working fine in almost TVs here. But there is one tv, actually my room's tv, that when I turn on the Pi3 the inicialization screen appears but when the recovery screen disappears there is no image from the recalbox. I know that this Tv doesnt work with high values of resolution ( in the xbox, I have to put on the low resolution to works on this tv ) but I dont know how to change the recalbox's resolution. I tried to change this:

    CEA 5 HDMI : 1920x1080 @ 60Hz 16:9, clock:74MHz interlaced

    CEA 4 HDMI : 1280x720 @ 60Hz 16:9, clock:74MHz progressive

    on the system config, but it wasnt effective.

    I read the recalbox's manual and found this:

    "You must connect the recalbox on a DVI screen but you have a black screen ?

    Just edit the config.txt file, and comment the line
    hdmi_drive=2
    with a # :
    #hdmi_drive=2

    On recalbox v4.0.0, /bootpartition is on read-only.
    So before editing your config.txt, you must mount your /boot partition with read-write rights.
    Go on root acces, then type this command : mount -o remount, rw /boot"

    But I didnt find this adress (/boot)!

    There should be no space between remount, and rw.



  • @paradadf I dont know where i do this! Where is the boots folder?

    @nubirro what can I say... on /boot
    That's the path. Go to the root folder and look the boot folder there.



  • @paradadf I really cant found this folder. Is there on /recalbox/share when I open the recalbox by my PC? Or I have to open the recalbox on the web by the Ip adress?

    @nubirro you can't access that parh through the web manager nor the samba share. As you wrote, the adress that is accessed is /recalbox/share which just doesn't match wirh /boot 🙂
    You need either WinSCP, Putty or direct access to make it. Look in the wiki for those. You need ro make the partition writable, wiki helps too.



  • @paradadf Ok! I did all the things that u said. I used the WinSCP opened the directory like the manual tolds me, use the comand:" mount -o remount,rw /boot" but I havent see the boot folders yet. I looked for some "config.txt" but I found the recalbox-config.txt and I didnt found the line that the manual told me to change (hdmi_drive).

    @nubirro you must be blind my friend. There is one other option. Plug your microSD to your computer and you should see the boot partition. That's the only partition that Windows manage to read btw. You cal also hold the shif key on a connected keyboard while booting recalbox. That should give you the possibility to edit that file directly.



  • @paradadf The best to edit the config.txt would be to do it through noobs

    FYI there can be a space between remount, and rw 😉
