VRR Incorrectly using frame doubling on 120hz displays

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.

Hi,

What ngocphi has said is somewhat true but not entirely. I'm sure they mean well but I little more explanation is required.

The Asus VG32VQ can do 120Hz at 1440P, however, the VRR (Variable Refresh Rate) FreeSync on this display tops out at 85Hz over HDMI. So for Xbox, 1440P 120Hz and VRR is a no go. You should be able to get to 120Hz with VRR at 1080P though.

The inability to do 1440P @ 120Hz is a limitation of your display's hardware, nothing to do with the older HDMI 2.0 port.

Most of these monitors rated refresh is based on their Display Port hardware.

Older TV's that have a '120Hz mode' are generally not true 120Hz displays. They do this by using a technique called frame interpolation. Frame interpolation is a process of inserting artificial frames between the original frames of a video signal. This creates the illusion of a smoother, more fluid image.



Frame interpolation works by analysing the motion of the previous and next frames in a video signal. The TV then uses this information to create a new frame that is halfway between the two original frames. This new frame is then inserted into the video signal, creating the illusion of a higher frame rate.



This is only useful when watching certain TV broadcast content such as sport as the image may appear more smooth and possibly less blurred. However, it can, and often does, include artifacts. And, when the action is too fast, additional blurring and even ghosting can affect the output.



You should not enable any TV post processing when playing games as this will cause severe input lag. It won't feel smooth at all.

There are no 120Hz games on Xbox One S. The 120Hz option was added as this is part of the feature set of the Variable Refresh rate technology feature added in around 2018. VRR syncs the display refresh rate with the game frame rate on compatible displays. This can prevent screen tearing.

Hi,

Unfortunately we don't have any other information than you do. I can tell you though that the reason 120Hz isn't working on all monitors is because of an issue with the display timings.

Usually 120Hz isn't 120Hz exactly. If I monitor has a none standard refresh of 119.88, but the console expects 119.98 then the 120Hz option will be unavailable. This should be an easy enough thing to fix if they put their minds to in. These none standard
refresh rates cause no problems with PCs as PC graphics cards are not tied to standard VESA display timings.

Also bear in mind that VRR can also be a factor. Many displays can only utilise the full refresh rate with VRR over display port. 120Hz without VRR isn't worth enabling.

Hi,

This is a very frequently asked question at the moment on these forums. Basically the display timings accepted by Xbox Series X are different to the timings (the frequency measured in Hz) that a PC graphics card will accept.

This is because most monitors don't use the standard timings put down by VESA (Video Electronics Standards Association), they have their own none-standard timings. An example of a none standard timing could be 119.88Hz instead of something closer to 120Hz
of 119.98Hz. Such timings cause no problems for PCs as their graphics cards are not locked to the VESA standard. This why 120Hz works on your PC, but not on your console.

I really hope that makes sense.

Bear in mind also that the LG 32GK650F-B, like many of LG's gaming monitors, has a 100Hz limit to FreeSync over HDMI. So, even if you could get 1440P @120Hz you can't use FreeSync. FreeSync is a Variable Refresh Rate technology that syncs the display refresh
with the games fps output. Without VRR you'll get screen tearing whenever the frame rate drops below 120 fps on games that support that frame rate.

There are no official responses to this issue from Microsoft despite the potential for a technically easy fix. So for the moment at least, you'll either have to drop to 1080P for 120Hz (and turn on VRR) or stick with 60Hz and VRR.

There are still benefits to using a monitor over a TV. Most TVs are still HDMI 2.0 and don't have VRR and users on these displays will get screen tearing, you won't have this issue.
