Raspberry Pi 4 stuck at max. 1024x768

I was able to run my brand new Pi succesfully at 4K the first time that I ran Buster.

From that moment on no matter if I reflashed (twice) the SD, if I change HDMI port or if I change HDMI cable the Pi does not go any higher than 1024x768... :?

I am using a OKdo 5,1V 3A power supply by the way.

Do I have to start thinking I got a faulty unit? :x

You should tell us what kind of screen you are using... Its the screen and Pi who usually agrees what is the best resolution.

It's a Samsung Q7F (year 2017) 55" LED TV.

I suspect it's because I am using a cheap HDMI adapter.

Ordered a micro HDMI to HDMI cable so let's see what comes up with it...

Ensure you are using HDMI0 (nearest the USB power connector)

Thanks I tried with both ports, but I suspect it might depend on the micro HDMI to HDMI adapter. 😅

I will post again as soon as I try the just ordered micro HDMI to HDMI cable.

Tip of the day :

DO NOT BUY MICRO HDMI TO HDMI ADAPTERS . IT'S CRAP !!

A straight cable (bought on Amazon for the same price btw) connection sorted the issue ! :oops:
