Xbox series x - no video output.

The ability to output 4K video is only a small part of the puzzle

The CPu and GPU of series consoles is far more powerful than any Xbox One. The Series S, while technically less powerful than the one x, has a far far more powerful cpu, the same one in the Series X

Fairly certain you can not dual monitor an Xbox One, and a splitter would only split the single video out. Here's hoping the Series X has dual HDMI outputs tho.

"The Xbox series S is a more than capable gaming console with an excellent power to price ratio that targets 1440p and can output upscaled 4k.

As a result you should not be getting significantly noticeable 'pixalation' over the series x."

The original poster bought an Xbox One S, not a Series S and was comparing it to an Xbox One X, not a Series X.

This problem is a tricky one, because the issue seems to lie either with the HDMI splitter, the capture card, or the HDMI cables that are in use.

I would like to know which Xbox console you have--if it's the Xbox One X or the Xbox Series X, which can impact on the amount of data that is being output, and in turn, can impact the video quality once it's being run through additional points and cables that don't all support the same quality of video that the included cables are meant to (I'm not trying to say that you can't buy those kinds of cables, I'm just using those hefty ones as an example).

For instance, the Xbox One X will output 1080p when playing games. The Xbox Series X will output 4k when playing games, almost 8 times the amount of data that the Xbox One X does.

You appear to have everything plugged in correctly from what I can gather based on your explanation, and if the Xbox console outputs the expected image quality when it's connected directly to the screen, it is likely that it's the items in-between that need evaluating.

I will do my best to see if it's the Xbox console causing any issues. If that's not the case, then my only recommendation is to make sure that the cables you're using from end-to-end can support the amount of data being transmitted from the console to the splitter, then from the splitter to the monitor and the capture card, individually.

Do you have a series console or a xbox one s or x

If the latter then no it's not available it's is only available on next gen consoles as it requires a lot more power then a xbox one can output

And no xbox one s or x Is not series consoles you are talking about 12 years difference in technology
