Dbk - macmini + LG tv = twice the screen at half the price of an iMac.
We have direct personal experience doing this and it worked out great.
Like colinng had read, we too saw many articles asserting that 4K tv’s don’t make good monitors.
But the price difference was so large, we decided to try an experiment -
We bought an LG 43 inch 4K tv to replace an Apple 30 inch cinema monitor that had been connected to a macmini.
The LG tv cost us $299 vs. The $4,000 we paid for the Cinema Display many years earlier.
The results were awesome. Gorgeous image with double the display area of the 30 inch cinema, and twice the pixels at 8 million for 4K UHD.
The Cinema Display was a good product that earned its keep over many years, and had a very good image, but the new LG is visibly better. We put up multi page documents with lots of small font text, and it’s razor sharp and much easier to read than the older Cinema Display.
It was a surprising result, but it is indeed awesome, so we got several more of these for cad workstations and software dev screens, and the team loves them.
There are newer tv models that are twice the price but their smart tv features don’t matter for professional needs, so this model from last year is really an outstanding bargain.
Here’s the link to this particular LG model on amazon -
Our advice on screens is to not over-invest right now, since industry is in a massive transition to OLED large panels, and they are technologically far superior for contrast, dynamic range, and viewing angle - just like on your iPhone X.
Right now OLED’s are pricey, but that will change in the next couple years since they are are wafer-thin and require far less materials cost to make, so they’ll end up cheaper than today’s lcd’s. They just need a little more manufacturing experience, and it will be all over for lcd’s.
So 27 inch iMac screens will soon feel very cramped, and you’ll be able to get a 65 inch super thin OLED screen for $800 in about 18 months.
The screens are changing so fast, it doesn’t make sense any more to build it into the box like the iMac.
Today’s macmini can even drive 2 or 3 of these screens - that’s like 16 million pixels and huge panoramic area for just another 299. But start with one, it’s plenty big.
Btw - now, even an iPad Pro can drive the LG 4K screen over usb c. So, soon you won’t even need the macmini either.
Once you use the big 43 inch, 8 megapixel screen, you won’t want to go back to the 27 inch.
Amazingly, it even plays tv from cable too.
