My point is that he needs a new video card to have normal 4k. It won’t work with that he has. Although I have no idea why one needs to bother about 4k on 43 inches.
I’ve got 75 inch and the 4k worths every penny on it, below 50 inch 1k is good enough.
You were being reasonable, I was being facetious.
My present secondary monitor is a wall mounted (same spot) 24" widescreen display mounted with the long axis vertical (so the input is rotated to match) which gives me 1680 vertical. This works for pages I want to screenshot but are often extend below the bottom of my primary screen (many a web page invoice, for example). But, then I give up width, and width is handy for side by side viewing of documents, viewing spreadsheets, and so on.
As far as text goes, the 1050h x 1680v pixel resolution on the present 24" secondary monitor isn't "bad".
4k 42” at monitor distance and I can *just* still see the pixels.
