Retropie boots to 640x480 resolution over HDMI

Question

I flashed the latest Retropie image (4.4) and it boots with a resolution of 640x480 when connected over HDMI to my 4k TV.

I used the correct Retropie image for my Pi 3. I confirmed the screen resolution using tvservice -s.

How can I get it to run at 1080p?

You can force a resolution by using raspi-config as follows:

You can also do this manually by editing /boot/config.txt and uncommenting and changing the following lines:

hdmi_force_hotplug=1
hdmi_group=2
hdmi_mode=82
hdmi_drive=2

or hdmi_group=1 hdmi_mode=16 – Jaromanda X Jan 15 '19 at 07:31
With hdmi_group=1 you use CEA. I experienced colour issues when using CEA on my TV, others may not. – Morgoth Jan 15 '19 at 15:52
fair enough - I read somewhere (though I can't find it, and it seems to be contradicted in official RPi docs) that using DMT, i.e. hdmi_group 2, will disable audio through HDMI – Jaromanda X Jan 15 '19 at 22:13
It might have for me, I thought it was an unrelated issue. If you follow this answer and don't have sound then do this: Why is my audio (sound) output not working? – Morgoth Jan 16 '19 at 05:53
