Dell S2719DGF Monitor support for 1440p at 120hz?

Hi

Was looking at a 27 or 32. I would like to purchase the Dell S2719DGF BUT I read that there are problems getting true 1440p resolution at 120hz on the Xbox with it. It apparently only lets you run 1080 at 120hz or 1440 at 60hz. The other 2 monitors you mentioned
are quite pricey. I live in South Africa and monitors get a hefty import tax. I am not sure if you known whether the issues with the Dell monitor supporting 1440/120 on the Xbox have been sorted out ?

Hi,

I've got some more information on your issue, unfortunately, you're not going to like it.

According to the manual, which you can
download from here. This screen does not support intermediate refresh rates such as 120Hz at 1440P. As for 120Hz at 1080P, I can't explain that as this refresh is not supported either.

From the screen shot below, you can see this monitor supports 144Hz (143.9 is basically 144) on the vertical refresh rate and 155Hz via Display Port. There isn't a 120Hz option listed.





Also, you'll note in
this review I found for the Dell S2719DGF, they didn't test 120Hz because it wasn't supported.

"Note that we aren’t testing other refresh rates such as 120Hz as the monitor does not include intermediate refresh rates such as this as listed resolutions."

As you can see, this isn't a console issue, it's a monitor one.

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)

I would look into your monitor and call DELL not Microsoft. I also have a One X and have never had any problems, as soon as select 120hz it automatically drops me down from 4K to 1440p. You must be misunderstanding something about your monitor as there
must be a defect of some sort or your monitor does not support 1440p at 120hz.

For reference, before responding I booted on both my One X's. One is connected to a Samsung 4K QLED and I had no problem switching from 4k 60 to 1440p 120. My other X is connected via an LG 4K monitor and again when selecting 1440p OR 120hz it automatically
selects 1440p or 120hz without any issues.

I'm having the exact same issue with my monitor. It's a Dell S2719DGF, supporting up to 2560x1440 at 144Hz over HDMI 2.0. I've tried an assortment of settings and HDMI wires; I even purchased an HDMI 2.1 wire to see if it was a bandwidth problem, eventually
coming to the same conclusion as you... It's a problem with the Xbox. I can run 1440p 144hz with Freesync/G-Sync enabled perfectly fine over HDMI on my PC with my RTX 2070. For now I'll be forced to stick with 1080p 120Hz until Xbox releases a fix, or addresses
the issue.
