Yes, you can connect the PS4 to the monitor with the HDMI cable.

Hello, I have two 24" Samsung screens of this type. I find it more advisable to use two screens of the same dimension. That way, the eyes don't have to focus on another dimension, which makes working much more pleasant. Unless you don't place the second one right next to it. Then the size plays a less important role.

No, it is not included and must be purchased separately. I have two of the monitors on the dual mount: King Mod Dual-Mount (Table, 24")

Tilting forwards and backwards is possible, yes, but you cannot rotate (portrait / landscape)

There are lots of them, look under monitor holder. I have fixed two of these screens to the table with the "Arctic Z1 Basic (table, 43") holder. TipTop.

Yes, normally no problem, with a USB-C (ThunderBolt) to HDMI adapter.

Unfortunately not 😅

Both monitors are Full HD and have a resolution of 1920 x 1080 pixels.

Yes, according to the following instruction manual page 21 "Removing the Stand (C22F390FH* / C22F392FH* / C24F390FH* / C24F392FH ....." http://downloadcenter.samsung.com/content/UM/201805/20180518095702048/BN46-00552H-Ger.pdf

No. This monitor does not support daisy chaining. According to my information, this is only available via DisplayPort anyway. And even then, the monitor must have at least 2 DisplayPort connections and support this in principle.

Yes. However, it is not a "real" gaming monitor. You can find gaming monitors here (More filters on the left): https://www.digitec.ch/de/s1/producttype/monitor-31?pdo=68-16663:7562&rm=opt~v68-16665:0.6096&tagIds=77-624

Hello Ives I bought the monitor about 1 month ago, I can only recommend it. To your question: Yes it works, I did it myself, but only with one monitor :)
