How do I activate 1440p resolution and 120hz refresh rate on my Dell G2724D Gaming Monitor?

Hi neversatisfied415,

I’m about 99% sure there is nothing wrong with your Xbox One. The supported resolution and refresh rate is 1080P/1440P @ 120hz. It wont go higher than that. As for that Dell monitor, on these forums I have come across people having issues with getting 120hz
over 1440P on that model. Could it be that the feature was not activated via firmware? Only Dell Support can help you there.

I have been thinking about a 1440P monitor for a while now and so far my research is pointing towards the Gigabyte models where the user manuals state support for 1440p/120hz. I am waiting to see what resolutions are supported by Series X and if we finally
get 3440x1440 before commiting.

My suggestion is before committing to any 1440P monitor check the user manual to see if it clearly states support for 1440P/120Hz over HDMI. I would also be looking at newer released models of monitors (2019 onwards)

So the Xbox will not do 144hz. You can increase your refresh rate to 120Hz for 1080p and 1440p resolutions. Your display must support 120Hz
over HDMI. Be careful as a lot of monitors only support higher refresh rates on the Display port and not on HDMI.

My advise would be to set the monitor at 60hz 1080p.

Yes I'm there and the Game is for 2k. So that is not the problem.

My Xbox One X will not accepted the Setting "1440p with 120hz" with my HP X27i Monitor. Do you now that issue ?

With a lot of monitors, the lower the resolution, the higher the refresh rate you can have.

Near as I can tell, that monitor has a native refresh rate at 1440p of 60Hz (that is what it defaults to)...it then uses Variable refresh rate to bump it up higher. As noted above, the EDID fails as the Xbox needs a 120Hz setting to run at 120Hz. The monitor will definitely do 120Hz via HDMI but only on a PC/Laptop it seems.

I can't confirm it but I suspect that the monitor's native RR for 1080p is 120Hz.

This has been an issue for quite a few HP models, both whilst using the One X and also whilst using the newer Series X/S's

That monitor supports 120hz ONLY at 1080p, and 60hz at 1440p according to the companies website. That would be why you cant select 120hz at 1440p

"With our monitors, you can run 120Hz at 1080p resolution. Or you can rock a pixel-perfect 1440p resolution at a 60Hz refresh rate. Even knowing this, you’re now able to enjoy buttery smooth gameplay
on one of the most popular game consoles of all time — thanks to FreeSync support"

Hi,

The issue here is usually the actual refresh rate of the monitor and what the Xbox expects the refresh rate to be.

When talking about high refresh rates, 120Hz isn't exactly 120Hz. Your monitor's 120Hz maybe 119.88 and the Xbox expects 119.98. Those slight specifics will make all the difference between being able to use 120Hz or not. Also, even if the cables are VESA standard, if the display isn't you're out of luck.

PC graphics cards don't use fixed refresh rates, hence the reason why you experience no issues with a PC.

Is this your monitor? https://www.mi.com/global/monitor34/

That's not a 1440P display. It's an ultrawide (WQHD). A true 1440P display is 2560x1440 (QHD). Any other resolution other than native on your console will have to be interpolated with a lower resolution stretched across the screen. This will produce quite a blurry image as Xbox consoles do not support ultrawide resolutions.
