VRR is greyed out when display settings are set manually vs. Auto-detect.

I just saw Alienware AW2720HF specs, my friend.

Take a look at this video:

On Display & Sound settings > Video fidelity & overscan > Display

Is it Overrides Auto-detect (Recommended)?

Sometimes if is not, if it is set to 1080p or 1440p, it doesn't allow VRR

Don't know why, since when it is on Auto-detect it is set to 1080p.

But see the video and try his recommended settings please to see if VRR option gets enabled.

I have checked the manual, it says it supports 1440p 120hz over hdmi the only thing it supports over display port is 1440p 165hz. So I will ask again why won't it let me set it manually hdmi then choose 1440p 120hz, but the option is available with auto detect. The monitor also supports VRR and free sync over hdmi.

It doesn't lol

Hate to burst your bubble but it doesn't support.free sync it supports GSYNC

IT IS a Freesync monitor!

As normal, ngocphi is getting confused with the technology. It's a GYSNC compatible FreeSync monitor.

As for why it see's 120Hz on Auto detect and doesn't when you select it manually is probably due to the display not 'talking to the Xbox' about what it's capable of doing, for want of a better explanation.

With 'Auto' set in the Xbox display settings, the monitor will tell the console via EDID (Extended Display Identification Data) what it can do and the console will change settings accordingly. The manual override is there mainly for trouble shooting purposes.

There are two ways to check you're getting 120Hz.

• The console either lets you select it in display settings or it sets it itself.
  
• A game lets you select 120Hz (120 fps mode) in its settings menu. Games like Dirt 5 have this within their options menu.
  

For best results it is highly advised you have VRR enabled. Without VRR running, games at 120Hz will see stutter. The reason for this is the fact that most games run 'up to' 120fps rather than a sold 120fps. When the game frame rate drops below the display refresh rate you'll get duplicate frames, these will manifest as stutters and the screen will tear. VRR keeps the display refresh the same as the game frame rate.

That's an odd one!

Go into your Xbox ones display settings and switch off auto detect. Then you can play with some of the setting manually until you figure out the problem.

Try the 50Hz setting and the 3D setting. (Also HDMI/DVI)

If you rely on the auto-detect TV feature you should try manual display settings and see if the problem still preserves.
