My HDMI does not work with the Arris cable box

[Novel8]

A couple of weeks ago I had Spectrum come to replace my Cisco cable box. In its place that gave me Arris. Never heard of them. Anyway after the repair man left, I went ahead to connect via a hdmi 2 x 1 splitter that worked perfectly with the Cisco box, but not with this one. I went to the store and tried to exchange for Cisco, but the attendant said they only have Arris, no more Cisco. So i returned home with the Arris. Experimenting with the hdmi splitter I finally got to view the cable channel on my Kitchen tv...BUT, it only works if i do not have the hdmi second output connected to my main TV. So as far as I know, I would have to do daily changing cables just to view in Kitchen. I'm talking about local channels that one usually gets with an OTA, but i get very bad or not even some channels with my indoor antenna. I have tried numerous antennas and still cannot get some local channels in my area which is NY and that is saying something. I see that they are selling Cisco box's on Ebay very cheap, but no remotes. So what good are those box's without a remote? Why would anyone buy them for the lack of a remote?

Arris is best known for their SURFboard cable modems which they used
to sell under the Motorola brand. You didn't give any details of the
Arris STB, splitter or the 2 TVs. If the STB is DCX4400 its HDMI
format is 2.0a which supports 4K and UHD. The splitter and each TV
might or might not. If the main TV does and reports that to the STB,
the STB might upconvert to 4K and either the splitter or kitchen TV or
both might not be able to handle that. Disconnect the main TV and the
Arris might drop down to the highest resolution the kitchen TV says it
can handle, which also works for the splitter.

Try connecting the STB directly to the main TV without the splitter.
Does that work?

The STB might have a setting to limit its HDMI output to 1080p and
non-UHD, which might fix your immediate problem. But if the main TV
can do 4K and Spectrum offers any 4K channels, you would only see them
in the lower resolution.

Yesterday a software update fixed my neighbor's HDMI problem.
