Analog vs Digital max resolution

Hi all- I was looking at options to create a 4-monitor setup by adding a video card (I'd probably replace my ancient video card at the same time, and buy 2 of the same brand/model), and 2 new monitors to go with the two I already have.

I am trying to research an alternative- I can get a 4k tv as large as (same total resolution as) my desired 2x2 monitor setup. Since all my work is in virtual machines, I can just size them to 1/4 size each and show all 4 at the same time, which is what I'm looking for.

I can get a 4x TV the right size for relatively cheap (~350), but as I look at video cards that say they can support that resolution, I'm seeing a lot of
"Max Resolution: Max Analog: 2048 x 1536 Max Digital: 3840 x 2160"
So digital is definitely what I'd want, but I'm confused by the distinction... especially since the cheap 4k TVs would rely on HDMI. HDMI uses a digital signal, but is there some reason it would be considered analog? It's not like those cards have some special analog output that I can see.

Thanks for any info!

You must be looking at videocards with VGA outputs, that's analog. DVI, HDMI, and Display Port are digital. You can simply get a videocard that will support all four monitors, but at least one of those monitors will need to have a display port input.

If you decide to use a 4k tv as one big monitor make sure it has support for chroma 4:4:4, as opposed to just 4:2:2 or 4:2:0. Then get one of the new generation videocards, like AMD's RX line or Nvidia's 10xx line. Those cards have updated support for 4k.
