Monitor Warranty

[TNA]

I am considering getting a 4k monitor this year, not sure if I can wait for new Dell ones to come out.

What I am wondering is, how does the on-site warranty on these monitors from different companies work exactly?

I do recall reading someone had an issue with an Asus 4k monitor and it was taking weeks to sort out. Is this the same for Samsung, AOC, Acer etc..?
In my experience Dell just send a panel out and it is with me the next day if something goes wrong. Does any other company do that?

By the lack of response I take it that it is only Dell who provide such service. Shame that.

Can't be too long for the Dell P2715Q to come out
