Newb - Intial setup, video stuck at 640x480

@Carbooja just to check... you are using an HDMI cable, right?

[Carbooja]

@columboscoat

Yes that is correct, brand new pi with latest build of retropi

TV supports 1080P

[columboscoat]

@Carbooja ok. I'll check my config.txt against yours.

[columboscoat]

@Carbooja You are missing a few hashes at the beginning of some lines. Is this a cut an paste error or your actual FULL config.txt file?

[columboscoat]

@Carbooja sdtv_mode should be commented out with a #.

[Carbooja]

yes its a cut and paste of my full config, let me hash out the sdtv

[Carbooja]

Same issue.

[columboscoat]

@Carbooja Did you reboot after the change? You will need to.

[Carbooja]

@columboscoat

This is what i'm doing, I power off the unit, I have a copy of the config.txt file on PC which i'm editing using notepad++

Once i've made the change, i plug in the SD Card into my PC, copy the config file on the the SD card overwriting the one there.

[columboscoat]

@Carbooja change HDMI_mode to 1. And reboot. Can you not just make these changes on the pi from desktop or using nano text editor?

[columboscoat]

@Carbooja Use the command line / terminal and enter "tvservice -s" no quotes. Post the output.

@columboscoat said in Newb - Intial setup, video stuck at 640x480:

tvservice -s

What commands do I have to run prior to this ?

I'm connected via putty now..

pi@retropie:~ $ tvservice-s
-bash: tvservice-s: command not found
pi@retropie:~ $

There is a space before the -s: tvservice <space> -s should get you the correct output

[Carbooja]

@mrbwa1 state 0x12000a [HDMI CEA (1) RGB full 4:3], 640x480 @ 60.00Hz, progressive

[columboscoat]

@Carbooja change hdmi_mode to 16. Reboot.

[mrbwa1]

@Carbooja My standard Config.txt has the following lines commented out:

uncomment to force a specific HDMI mode (this will force VGA)

#hdmi_group=1
#hdmi_mode=1

So as stated, change to hdmi_mode=16 (and you can probably comment out those lines if you are going for the standard 1920x1080 resolution).

EDIT: hdmi_mode=16 is the standard 1920x1080 and what is used if the lines above are commented out.

[columboscoat]

@mrbwa1 tvservice -m cea will show him all resolutions and frequencies supported. To the left there will be native and prefer. Mode 16 is the preferred mode. My TV is mode 31 (native) @50MHz because I am in Ireland and that is standard. The same for the UK.

Thanks for the clarification. That's what I get for only half-paying attention to the question. I forget that my TV is 1080P 60Hz native even though it's only a 720P TV.

[Carbooja]

We're good!

I think in hindsight, disabling hdmi_safe=1 mode and then setting hdmi_mode=16 did the trick.

Thanks for all your help!

Now time to explore this thing :)

[columboscoat]

@Carbooja Glad you are sorted. Have fun.
