Re: New Pi 4 4gb no HDMI

There are two HDMI ports on the RPi 4. For me, only Port 0 (left hand one) works.

Re: Converting Arduino code to Python Code

Please excuse my ignorance - it's several years since I used Arduino.
But why don't you just connect the Arduino to a USB port on the RPi and run your sketch on the RPi?

Re: xrdp works until reboot

Been there, done that.
Eventually, I gave up fighting it.
Instead, use RealVNC which comes bundled with Buster.
You just need VNC viewer on your PC.

Re: Raspberry Pi 3 B+ availability

There may be people on this forum who have surplus 3B+s, having replaced them with RPi 4s.
This may tide you over until Apr 2020.
I got rid of 4 RPi 1Bs recently to someone in a similar position to you.

I get sound with HDMI 0, but it is very faint, and to hear it I must have 100% volume on the TV .

Re: How to connect WiFi on RPi4 and Raspbian Buster on startup?

Have you tried shutting down, disconnecting the ethernet cable, then powering up?
This will remove eth0 from the equation.

And the lugs on the sides of the PS are really annoying if you're using a power board, because they protrude over the adjacent slot meaning you can only use every second one.

Re: Raspberry Pi 4 Thread - general discussion

I'm running buster on an RPi 4 4GB. The RPi is connected to a Samsung TV by HDMI cable.
In Chromium, when I try to stream, the pictures come through just fine, but I need both RPi and TV at 100% volume to hear sound.
Is there a way to tweak the volume up a bit?

Re: Raspberry pi doesn't get ip while ssh is enabled

With the standard configuration the Pi expects to get an IP address via DHCP. Windows 10 also expects to get an IP address via DHCP. So if you connect them together on the ethernet ports they are both going to 'ask for' an IP address but thete's no router providing an answer. So you'd need to eithe...

I'm using a RPi4 4GB to stream TV in Chromium, with HDMI connection to a Samsung TV.

Re: Can't access Pi over WAN

I had this problem with a previous router. It would not allow "hairpin routing", so to access my website using its external IP address, I had to use a machine outside of my LAN. When I replaced my router, the problem went away.

Re: Backing up 32 GB SD card on Windows 10

IMHO, it's better to back it up onto an SD card using Accessories/SD Card Copier.
Then , if the SD card fails, you just slip in the backup card and you're away again.

Having said that, I do a nightly backup of programs and data to Win 10 using WinSCP

Re: Can't connect to website via external IP

Sounds to me like a problem with your router.
To connect to your site using an external IP, the router must do what's called "hairpin routing".
Not all routers have this capability.
Maybe your router can do it, but not well.

Can you connect to your site from outside of your LAN?
