@joelw23 the webite with the resolution settings isnt working so i cant tell you what the hdmi mode is for 1280x1024 since i am not home at the moment but add this setting too.

hdmi_force_hotplug=1

joelw23

Thanks but that setting is on as well

@joelw23 change your hdmi mode from 16 to 35. You can try 37 as well but i believe 35 is correct for your monitor

joelw23

tried 35...still nothing..

config.txt here:

also just tried another vga cable just to be sure.. same result

when i unplug the vga cable the monitor goes in to "self test feature check" mode

when the vga cable is plugged in, it goes right in to sleep mode with the yellow light on the power button.

BuZz

@joelw23 if posting configs, please put them in a code block for readability http://commonmark.org/help/

I have also tried a usb cable that plugs in to the wall in case the pi3 wasn't giving enough power...

monitor is still in power save mode with no signal.

joelw23

the company that sold the adapter is sending me a new one to try...

hopefully this one is defective.

@joelw23 this could be a possible issue or it was from how you copy and pasted, but why do all the words "uncomment" not have hashtag "#" in front of them?

joelw23

must be how it copied an pasted...they do have a # in front of them in the config.txt file

Hmmm, I got this model :

And It worked for me, but needed to set "hdmi_drive=2" (uncomment the line in /boot/config.txt) for get a good quality image; if not, the colours looks strange.

Note: Uncomment means that you should delete that # to get that code line working (no spaces too)

@flop ditto. i use this same one. i also have another type that works too but i like this one much better because of quality

@joelw23 , I forgot it, when I use my vga - hdmi adapter, I need to make a "sudo reboot" via putty for get my monitor showing the image, it´s strange but it works (I put rpi ON, then via putty "sudo reboot" and the monitor displays the rpi)

joelw23

turns out the adapter was bad...

they sent me a new one and it worked with no issues.

@joelw23 awesome. It sucks when you are relying on something as important as that and its defective.
