Monitor not able to run 1440p at 120hz on Xbox Series X

[fourboons]

It’s not a for sure answer but maybe this would help. I am having the same exact problem but my monitor is not an hp. It’s a Viotek and it has 1440p at 144hz. I have tested it on my computer through and hdmi 2.0 and I know it is capable of that output. It’s sounding to me like it’s an Xbox issue and not a monitor one.

Everybody, I was having the same issue as you guys. Could not figure it out was super pissed. I found the solution!!!

it’s in your xbox settings. Watch this YouTube video https://youtu.be/p93nCfgH38A

As the video refers to an Xbox One X and not an Xbox Series X, can anyone confirm that the suggestion in the video is working?

I would like to use 1440p @ 120Hz once my Xbox Series One comes in.

Thanks in advance.

In addition to my previous message, apparently if you change the settings in the Xbox to 8-bit color and then you should be able to do 1440p @ 120Hz, you can even put 10-bit color back afterwards. Can anyone confirm?

I've tried everything - none of it works. I bought a new monitor not from HP and it runs 1440 120hz fine - i'll just sell this HP one now 🙄

How do you change the bit colour settings on the series x to allow both 1440p and 120hz?

[Passittokobe]

I can confirm it works with Series X, that’s what I used it for. Should work for120hz. And yes you can change the color bit settings (I’m not too keen on what that is but I see the options for it) 

Edit: I don’t think this monitor runs 1440p though. At least not the one I have

Anyone got anywhere with this? Don’t want to have to send this monitor back when nothing suggested that it wouldn’t run 120hz/1440p

This is the thread. Its because the HP monitors use non standard refresh rates. Meaning that the xbox does not detect its compatibility with 120hz (i think the HP are like 119.88 hrtz) 

Xbox have said they are going to release an update, but so far nothing. Samsung and Asus monitors work at 1440p 120hz fyi

"Native resolution (QHD (2560 x 1440)),Maximum resolution (QHD (2560 x 1440 @ 144 Hz))." HP spec, page quote"

Plus this ,

1 DisplayPort™ 1.2; 1 HDMI 2.0

"The HDMI standard is a high-level specification, it recommends a certain number of video formats, but it does not impose any of these formats. It is then up to the manufacturers to decide which video formats they want to implement or not in their HDMI interfaces. If you buy a TV with an HDMI 2.0 port, for example, it does not mean that it will be able to handle all the video formats offered in the version of this standard."

knowing that , my linked up eDID app below ( shows what you have)

in the old days,  (omg 10 year or back)

the top 10000 monitors sold have a  guide, you open said guide(RTM) and there is this great matrix of supported sweep rates.

H x V x refresh rates,

with Y/N in each box.

but then came monitors with 3 ports?  DVI and HDMI and DP, (VGA is dead so forget it) (yours  is only HDMI)

and versions different (rules) of each VESA specs. (matters big time)

so many makers of monitor got lazy and didn't not want to do that 3times, all 3 ports. 3 matrix's. (but your mon  is 1 port)

The xBOX must support this,  and only MS knows that never HP. even XBox versions not the same. wow. HW/SW both.

The PnP rules and logic flows like this....

but this is  what happens, in ALL OS,  the PC (or xbox) sends out a command to the monitor on the eDID pin to the EDid chip in the monitor and guess what this edid table has all the facts you can not see in the silly manual.

the eDID chip shows all things the monitor can do, if xBOX likes what it sees it can do all those modes.

see this APP, see this run this and see all the facts just one program app , free and 100% safe

here is my old View sonic, 

the Xbox must like what it sees here, IT MUST, if not ask MS why not. (gpu card limits or OS limits , i could never guess)

now you know what eDID does,  the plug and PLAY info chip seen in ALL MODERN monitors made.

Pins 13 to 19 on the HDMI cable must be correct ,no missing or bent pins or PnP can fail easy,  modern cable is BEST !!

also hot swap cables can fail, boot the PC cold to get full resolutions do not hot swap cables and wonder why it fails.

You now have the power to see why it fails  hardware is 1st then MS XBOX limits is 2nd.

cheers and happy holidays to all.

I call XBOX foul ! but  use the app above, and see if there are holes  in the  MATRIX. (what if there are older versions of this  monitor that is missing support there)

The VESA rules set this, up, if XBOX does not comply with the VESA rules, it fails.  HP is not MS.
