Build 4077 D7 HDMI problem

Hi everyone,

I have had nanodlp running for a long time with no problems.
I have updated to build 4077 and have had update errors.
In order to solve it:
I have saved the machine configuration and profiles
I have saved config.txt
I have formatted and done a clean install of build 4077.

I cannot display images on the screen.
Does anyone have the D7 running build 4077?

Config.txt

Re: Build 4077 D7 HDMI problem

If I compare my configuration export with the one available on the nanodlp.com website, I see that in the last builds fields have been added. The same thing happens with the manual https://3dprinterwiki.info/d7/d7-nanodlp-settings-2/

Re: Build 4077 D7 HDMI problem

It could be a firmware issue.

Re: Build 4077 D7 HDMI problem

No I mean raspberry Pi firmware. Image you are using as OS must probably utilize different firmware.

Re: Build 4077 D7 HDMI problem

Does it work with other displays? If yes it is good idea to contact LCD manufacturer, some settings config.txt may require change on newer pi firmware builds.
