Dual-link DVI was a very short-lived item, as was Apple's ADC (DVI + power on the same connector). Supporting those going forward? You're basically doomed.
That's what I'm concluding. Looks like I got stuck in an in-between state. My monitor's 2560x1600 resolution is very uncommon these days.
It always seems like small, simple upgrades have unintended consequences for me.
Isn't that the truth! I had totally forgotten about the dual-link DVI issue. I now remember running into it the last time I upgraded my desktop. I ordered a lower-end graphics card because I don't game much, but it didn't support dual-link so I had to swap it for a better one. Annoying.
... someone will say "no, dummy, this $10-30 cable/adapter will get you what you want!" ...
Does
this help?
Unfortunately, all that does is make me conclude that it isn't worth it. In fact, It tells me that I underestimated the equipment necessary for this. I'd have to do this in two steps instead of one, and it'll probably cost around $200 just for the adapters.
Given that and the cost of the Dell dock, I'm starting to weigh all my options. USB C monitors are still really expensive. I'd love something like this
LG model, but $700 is a lot.
The other options, though, aren't much cheaper. The least expensive decent 4K monitor I can see on Amazon is around $370. That and the Dell adapter cost about $510. At that point I'd honestly consider spending the extra $200 for the USB C monitor.
Or, I could go with a lower resolution but smaller monitor. The problem is that I've been spoiled. Going by PPI, my current 30" monitor is 100 ppi. My XPS 13 is 169ppi. A FHD 24" monitor is 91ppi, and it's noticeable to me. Maybe I sit too close, though

What monitors do you all use?
