I use this monitor with item number 12874435 for less than 52 CHF. Works like a charm.

The Samsung Odyssey G6 - G65B (27") should in principle be compatible with a current Mac mini as it has HDMI and DisplayPort connections that are typically suitable for Mac computers. However, there is no specific information about VRR or HDR support with macOS devices in the data provided. It is advisable to check the exact specifications and possible limitations related to macOS to ensure that all desired functions work properly.

144hz is not a native setting for this monitor, try creating a custom configuration to set 144hz.

EDIT: The Samsung Odyssey G6 - G65B monitor can indeed be rotated 180 degrees. Here are the exact details on adjustability: - Pivot: -92.0º ~ 92.0º.

I don't have a camera

which camera would you recommend

There is one included yes. You can operate all settings with it & use Netflix and co. as quick access. Set volume up/down etc. Just like a TV has.

Yes, as long as it complies with the Vesa standard, you can do it.

Small TVs that are not specially designed for gaming have a high latency, i.e. what you do with your controller is displayed on the screen with a delay. This isn't a problem for cosy games, but it ruins the fun for faster or competitive games. The PS5 outputs a maximum of 120Hz at 4K video resolution. Look for something that supports this so that you can use the full potential of your PS5, this monitor can display up to 240fps but "only" in Uhd (2K).

They are very similar. LC27G75TQSRXEN has a better colour space and has HDMI 2.1 connections, which is especially interesting for consoles (One X and PS 5).
