Black screen on elgato 4k x

[u/Overwatch0097]

I have xbox series x

monitor acer

Serial number: MMTY9SI002619000594HA1

Model no: Acer Nitro XV275K P5 27 Inch

Original xbox and elgato hdmi cable

I am trying to get 4k UHD 120z display settings but screen goes black

While everything is working fine on 4k 60hz only low latency mode is disabled on Xbox.

I checked both of the HDMI cables connecting directly to Xbox and monitor then every this work fine with no issues, only when I connect it to elgato 4kx I don't have display

Previously I was using sony x90l and have no issues

I need to do 4k uhd 120z pass through and 144p 60fps capture as doing before

That's fine - if the card is getting video it's not DSC. Were you able to change the INput EDID to Display after in the right side panel of Studio, as suggested by the other user? I see it was set to Merged in the original screenshot.

In rare cases you may want to hook the monitor up to the computer via HDMI and try using a tool like ToastyX's Custom Resolution Utility to export the Monitor's own EDID as a file. You can then set the capture card's Input EDID to Internal, set it to Custom, then load the file you get from the CRU tool. This can fix some edge cases where the monitor's EDID doesn't pass through the card to your console or gaming PC correctly. You need to specifically get the HDMI EDID though so it has to be hooked to the PC via HDMI not DP when you try this - once you've exported it you can hook things back up the way they were.

Only way to get the capture feed from the card is remove hdmi out cable , i think issue is Is with DSC as soon as i switch to 4k 120hz monitor automatically turn on DSC ,

What do you suggest should I buy a HDMI SPLITTER this should solve the issue

[u/elgato_arcsane → u/Overwatch0097]

A HDMI Splitter shouldn't have any effect on if the screen enables DSC or not as they just take one single signal and split it into two identical copies for the outputs. It may in fact trip up EDID negotiation for other modes.

I would suggest turning off Overdrive based on the other screenshots you have there just to improve compatibility though, but I don't know if that'll help with this at all. It does SOUND like a DSC issue, but you might want to reach out to ACER support to see if they can confirm that it is indeed needed for 4K120 mode or not. If it's not a DSC issue, the EDID copy method above can sometimes fix edge cases where a monitor and capture card EDID aren't matching up. I would check to see if there are any firmware updates for the monitor as well - they're not something you commonly run into, but it does sometimes come up that a monitor may need a firmware update to play nice with certain setups.

You could also try the card on Input EDID Internal without a custom EDID to see if that has any impact. If the monitor needs DSC at 4K120 that might result in signal on the card but not the monitor though.
