Can you run, from a SSH session:

tvservice -s
tvservice -p

and post the output ?

Hi I don't have ssh enabled, watching a tutorial on how to do it. Since rasberry pi doen't connect to my dell, I have connected to my tv via HDMI/DVI cable and will get ssh enabled before connecting it back to my dell monitor using ssh

Hi, finally enabled SSH and installed WinSCP on my PC so my pi and PC showing same network. I switched my rasberry pi back to my dell monitor and have SSH ready to use

Going to be a noob here, how do I get the output?

You need to use Putty, not WinSCP, to run those commands.

Hi, thankfully I installed Putty before, finally got it working


pi@retropie:~ $ tvservice -s
state 0x12000a [HDMI DMT (4) RGB full 4:3], 640x480 @ 60.00Hz, progressive
pi@retropie:~ $ tvservice -p
Powering on HDMI with preferred settings
pi@retropie:~ $

Thanks

@mitu Also, I connected my raspberry pi to my TV as it works but for some reason, no signal from my pi to the TV. Used the same cable as before but since the changes I made, tv is blank as well, no signal.

@mumihp You can back-out the changes you've made (the config.txt modification), but I don't see how that would impact the TV image. The commands you ran are not changing any settings, they only probe and power up the display.
What version of RetroPie are you using ?

Hi, I am using retropie v4.5.1

Thanks,

Looking at the specs of your monitor, it looks like the native resolution is 1280 x 1024. Try forcing this resolution by modifying the config.txt file with the video mode for this resolution - see https://www.raspberrypi.org/documentation/configuration/config-txt/video.md and look for hdmi_group and hdmi_mode.
Add also

hdmi_ignore_edid=0xa5000080
config_hdmi_boost=4

to those configuration and then try again to see if you get any video.

Hi, it seems my HDMI has stopped recognising anything. Since the changes, pi won't work on my tv or hdmi monitor (did before) so I basically did a fresh install of retropie. No matter what I do, I get the no signal on the tv/monitor. I don't understand if I did a fresh install, surely it my pi should be as I never changed anything so me connecting to the TV or my other monitor should work.

Honestly, it's frustrating, spents hours over the week, tryig to fix it after work. Worked great at first but now, nothing on anything. Atleast if it didn't work on my dell monitor, still could use it on my tv or other monitor but nothing now.

Could it be that your cable or HDMI port are damaged ?

Hi cable works fine, tested it with my other devices but nothing with rasberry pi. I don't know if it broke recently with me pulling it out often but decided to buy a new one, but will wait until the prices comes down, which it should since pi 4 came out recently.

Anyway, thanks for the help.
