Xbox Series X not showing on screen after overiding display to HDMI

Can't say for sure. This is an older HDMI 2.0 monitor. While most work, some of these displays limit the HDMI refresh rate to 100Hz, which would make 120Hz impossible.

You likely won't find this information any many reviews as Display Port is the common way to connect these displays to the main system they were designed for, PCs. Connecting gaming monitors to consoles in a recent thing, and not all monitors work well with Series X over HDMI. Just because the specs say 165Hz, doesn't mean you're guaranteed to get 120Hz over HDMI.

These monitors however, are all compatible with Xbox Series X|S https://www.rtings.com/monitor/reviews/best/xbox-series-x

For the monitors that fully support 1440P @120Hz, HDMI 2.0 is enough. You don't need HDMI 2.1. The Samsung G5 1440P is one of those monitors. However, the rated 165Hz is for PCs running the monitor through Display port. That being said, HDMI 2.0 on this display has enough bandwidth for 1440P at 120Hz.

The important thing to note is that Xbox One X or Series X isn't like a PC and games won't run better automatically just because you've got a 1440P display. Many Xbox Series X games will still render internally at 4K and will be downscaled to the lower display resolution. You'll only see improvements in performance if said performance options are available in the game. As far as I'm aware, ACC does not have a 1440P performance mode. It doesn't need it though as it a pretty solid (for the most part) 60fps game - well, it is on Xbox Series X anyway.

These gaming monitors have a technology called FreeSync which is also supported by the console. FreeSync eliminates screen tearing and judder when performance drops.

I tried every hdmi port that’s brand new and nothing works

It sounds like you are experiencing some issues with your Xbox Series X. To troubleshoot the zoomed-in display on your TV, you can try the following steps:

1. Check the display settings on your TV.

- Some TVs have a "Zoom" or "Aspect Ratio" setting that can cause the display to appear zoomed in. Make sure this setting is set to the correct value for your TV.

2. Check the display settings on your Xbox Series X.

- You can access these settings by going to the "System" tab in the "Settings" menu, then selecting "Display & sound" and "Video output". From here, you can adjust the display resolution and other settings that may affect the display's appearance on your TV.

3. Check the HDMI cable and port.

- Ensure the HDMI cable is securely connected to the Xbox Series X and the TV, and that the port on both devices is free of any debris or damage.

4. Try a different HDMI cable.

- If you have another HDMI cable that you can use, try connecting your Xbox Series X to the TV using that cable to see if it resolves the issue.

If you continue to experience issues with the zoomed-in display on your TV after trying these steps, you may want to consider seeking assistance from Xbox support or a professional repair service.

Note also that during setup, the Xbox One X default resolution is 1080p, If the console detects you are using a 4K display, it will prompt you to ask if you wish to change to 4K. If not, you can change this manually from the settings screen.

You can see if your TV is displaying correctly either from an information button on the remote, or by simply changing the HDMI source back and to the Xbox One X again. This will usually show a information pane at the top of the screen showing the resolution
your TV is set to.

On my Samsung it says UHD 3840x2160.
