Question on video resolution

Post by mtcawirtz » Tue Aug 07, 2018 4:31 am

I just got my hardware today. I hooked it up to my arcade and the screen was garbled. I figured that since my CRT is HD I would have to change the settings. I took the PI up to my other TV and hooked it up via hdmi and started just fine, I went into the gui settings and clicked on Vertical High Resolution by accident. The screen went black and now nothing is showing up. Not sure what to do now, can I default it at all? I am a complete noob here. Any suggestions would be great.

Selecting the vertical high res option should have made the system reconfigure itself and reboot unless the option was still commented out for low res monitor safety in which case nothing should have happened at all. There is a default horizontal low res option in the menus but if you cannot see them that doesn't really help you either.

Just to confirm: when you power on the cab now the screen just stays blank? When the system is powered up does the RPi have any activity on its LEDs? Can you post the contents of the file /boot/config.txt (with the SD card in a desktop it will be the file config.txt on the first partition of the SD card) - it may give me a clue what's going wrong.

Did you download the software or were you supplied it with the RaspberryJAMMA? If you downloaded it the easiest way to return to standard settings would be to just re-image your card, not really an option if you bought it and haven't made a backup though.

If you don't have one I would make a backup of the card before doing anything else. It may be too late to make a quick easy restore you can use but at least you will have everything backed up if you make an image of the SD card, that way you cannot really make things worse than they have already gone while trying to fix it. If you copy the roms, menu themes and preview videos off the SD card you could rebuild it with a fresh copy of ARpiCADE 3.82 and then copy the games, previews and themes back but it may not be necessary to get you fixed up.

I had it hooked up to my LCD monitor because the CRT (Via VGA) was scrambled and I couldn't read anything. This is why I thought it was the resolution settings. It came up great via HDMI on my LCD and I changed the video setting in the settings tab within arpicade not Raspberry Pi. The screen went black and can't see anything on the LCD via HDMI but same garbled screen on the CRT (Via VGA). I ordered the 64gb Sd card from you with all of the horizontal games included. I can get the config.txt at lunch.

Looks like you actually switched the system into the 240p only non interlaced modes mode. In your config.txt change this section:

# Boot and menus in 240p (all games in 240p/256p/288p)
hdmi_mode=8
# Boot and menus in 480p (no res switching, just 480p)
#hdmi_mode=1

so it becomes:

# Boot and menus in 240p (all games in 240p/256p/288p)
#hdmi_mode=8
# Boot and menus in 480p (no res switching, just 480p)
hdmi_mode=1

and save the file. Next time the Pi will boot in high res. Had to Google your TV, looks like it should work fine even though I am not familiar with that one I used to use a SONY HD CRT pretty regularly without any issues.

I don't remember selling you anything... must be the username confusing me. Or you think I'm someone else maybe.

Same config.txt file this time near the top, find this:

# Comment/uncommment to flip the image to account for monitor mounting
# this is a 180 degree flip NOT hori/vert mounting
# (see bottom of file for horizontal/vertical mount option)
display_rotate=2

and change it to:

# Comment/uncommment to flip the image to account for monitor mounting
# this is a 180 degree flip NOT hori/vert mounting
# (see bottom of file for horizontal/vertical mount option)
#display_rotate=2

and the picture should be the right way up again.

Here is an update. It boots up fine. I can scroll through the games etc. Looks great. Then I click on one of the games and the video goes funny again. I have attached pictures. I am sure that I am doing something wrong. I will attach a new config file too. Thanks so much and sorry to be a pest.
