HMM, my laptop has a Skylake i7 and can output 4K to 2 external monitors simultaineously, so I doubt the claim of 4K needing Kabylake i7s to display 4K. The graphics card is an Nvidia GTX 960M.
I was uncertain beforehand, but as soon as I set it up I was converted. My desk is against a wall, so I don't lose anything that way.
Two bricks, but I will find something better. Probably.
And thanks all for the input.
Cheers
You have a GPU so the type of CPU is irrelevant. If you want Intel integrated graphics to do 4K@60Hz you'll need Kaby Lake if your monitor wants HDMI 2.0. If your monitor can take Displayport you can do it back to at least Haswell, maybe before.
(Converting from DP to HDMI is doable but costs about as much as a GPU)

That's about what I recall too but maybe needs a 760 for DP (and a power requirement about 3x that of the 750).
The question is more can it do it *without* using the graphics card - just using the on chip HD Graphics. The only thing that my i7 3770 on chip graphics can't do is support video picture in picture which is a nuisance for video editing but otherwise not a problem for me.
I am pretty sure the 7th generation CPUs can do 4k @ 60Hz natively with on chip hardware without needing any external graphics card at all (motherboard connectors permitting). There is a slight hit on shared memory bandwidth doing this which will get worse at higher resolutions.
Ah! point taken and thanks.
Yup. Like many, I started out with a 14" 4:3. And have increased to size over the years. Now a widescreen 24" - and unlike the previous sizes don't think it would be nice to go much bigger.
Oh - a 40" wouldn't fit here without some 'building' work. ;-)
Who are "we"?
Graphics cards only use a couple of hundred watts when in use. Sitting with an unchanging screen uses bugger all.
I find even the latest onboard graphics sluggish for day to day windows usage.
That's a good point. My experience of lack of scaling support is on a
15" laptop with a 4k screen, where it's really noticable and almost unusable in some cases. I can imagine that a 40" monitor wouldn't be as much of a problem.
No it doesn't. An adapter is about a tenner or so, I looked them up once before.
When using a TV as a PC monitor, you need to be sure it has the option to turn off over-scan or other scaling nonsense.
And be able to turn off under/over scan scaling on the GPU on your PC.
You need 1:1 pixel mapping, ie the resolution of the panel needs to map directly to the resolution you are feeding it.
Yup, two of them side by side works for me ;-)
A 40" 4K used in "portrait" orientation might work!
This is what put me off varifocal glasses - restricted FOV.

Need to buy decent lenses. I'll give you that they aren't cheap.
I had a bit of a problem with my first pair which had quite small lenses.
The solution is to choose a frame that that suits you, takes the largest lenses possible and pay a little extra for the superior grade of varifocal lenses.
Mine came from Specsavers and the incremental cost for the lenses was quite low but looking as far to the left and right there are no aberations, just excellent wall to wall vision.
Considering that you effectivelu get three pairs of glasses for the price of one, the cost is quite reasonable even if you have to replace your glasses every year. It is worth it to me for the sheer convenience alone.
My frames and initial lens costs are always well under £100 and a 25% reduction based on being over 60 makes one pair a better option than their two for one offer so I always pay extra for the anti-scratch coating and photo-chromic lenses.
This. Those tiny little lenses that are trendy at the moment are hopeless.
Bigger lenses are available - but not from the chain stores.
My current varifocal lenses are certainly smaller than the previous ones, but work perfectly well. I've been wearing VF lenses since 1990 and would hate to give them up; I'd be forever swapping glasses.
Follow-up.
Today I bought a 43" LG 43UH650V for £399 from Argos for use as a monitor, and I'm very pleased with it. 3840x2160 at 30Hz is just great for my needs.
