Alienware AW3418DW & XBOX One X 1440p Issues

So yesterday my brand new AW3418DW arrived. Very exciting!!

On PC it is sublime, paired with a GTX 1080ti via DisplayPort.

The excitement didn't last long though! On XBOX, its a different matter.

Using the HDMI port on the monitor, I connected the XBOX and turned it on. I saw what I expected, a 1080p image (black bars on the left and right side of the monitor). So I went to the XBOX settings and changed automatic detection to HDMI, this then allowed me to choose 1440p from the resolution options.

As soon as 1440p was selected, the monitor goes black and enters power saving mode, a few seconds later, the monitor turns on again and the XBOX resets its resolution to 640 x 480.

I tried different settings, like colour space settings, selected allow 50Hz etc etc. Nothing would allow 1440p to work on this monitor, it simply went into power save mode every time. Oddly, there was only two refresh rate options available, 60Hz and 120Hz, no option for 50Hz. So I gave up and left it at 1080p.

Everything seemed fine in 1080p mode. I fired up BF1, had a few games, enjoyed how smooth the image was on the AW3418DW. A friend calls me and said I have a beer waiting for you round the pub, so off I go for a couple of beers, while leaving the XBOX on and in the BF1 menus.

On returning from the pub, I noted the XBOX was off, nothing unusual, but when I turned it back on, I have no image, a black screen. So I did the usual hard reset by holding the power button down for 30 seconds. I can hear audio coming from my headset, but no image on the AW3418DW. Went through the process of hard resetting the XBOX several times, all efforts failed to bring back and image on the AW3418DW.

I started troubleshooting, first by trying various different known working HDMI cables, then connecting my Mac Mini to the HDMI port on the AW3418DW, all fine, nice and perfect image from the Mac Mini. HDMI port on the AW3418DW seems fine. All HDMI cables seem fine.

I then connected the XBOX to my original BenQ RL2755HM monitor that it was initially connected to (and worked fine for months). And of course, no image. Seems as though the XBOX will no longer output from its HDMI port.

I tried the video reset procedure, which didn't work. I tried doing the full factory reset of the XBOX by using the USB method, that didn't make any difference.

Image output from my XBOX if officially dead!

I refuse to believe this to be a coincidence. New monitor = none working XBOX.

So I did a little reading, like you would in this situation.

Turns out the XBOX One X 1440p support is limited to 2560 × 1440. And of course the AW3418DW does not appear to support this resolution, according to the manual, the HDMI port supports the following range of resolutions and refresh rates:

• IBM VGA, 640 x 480p


• VESA, 720 x 480p


• VESA, 720 x 576p


• VESA, 800 x 600p


• VESA, 1024 x 768p


• HDTV, 1280 x 720p


• HDTV, 1280 x 720p


• HDTV, 1920 x 1080p @ 50Hz


• HDTV, 1920 x 1080p @ 60Hz


• 3440 x 1440 @ 50Hz


As you can see, no mention of 2560 × 1440.

I just find it hard to understand why the XBOX would stop outputting an image. Did I fry the GPU by selecting the 1440p option a few times?

Luckily the XBOX is under warranty as its only a few months old. New one on its way. But I am now very reluctant to connect the replacement XBOX to the AW3418DW. Even if I leave it in 1080p mode, as this was the mode I was playing BF1 on before I left for the pub!

Unless I am being stupid, or missing something completely, or the AW3418DW I have is faulty in some way, I cannot recommend the AW3418DW for use with the XBOX One X. At least not in 1440p mode!

Has anyone here successfully got the AW3418DW to work at 1440p on their XBOX One X?

I no have the Alienware 34" monitor

But I do have the Asus PG348Q ROG Swift 34" 3440x1440 monitor and an xbox one X so I have a go and see how the xbox one x works on it later this evening.
As I have never tried using my xbox one x on my PC 34" monitor
