I am about to order LG's new 65 UHD TV to use as a monitor for nMP. It has HDMI 2.0, so I am assuming that I will be able to use it @60hz down the road when nMP gets some kind of HDMI 2.0 update. Is there any reason not to buy this TV now? I am also assuming that I could run this at UHD@30hz right away, am I correct?

Thanks.

Probably will be an adapter Thunderbolt > HDMI 2.0
But i don't think will be any kind of upgrade of the embedded 1.4 hdmi to 2.0.

a 65 inch screen in your face sounds unpleasant...i wouldn't buy anything 4k until things are ironed out and running solid for a couple months. Thats just me tho

not really in my face. ;) Yeah, I want to see what Apple comes out with but I doubt that I can wait.

It's finally here!!! Right out of box, it sees all the resolutions upto 4096x2160@24hz. But I can't seem to get HiDPI mode. Updated to the 10.9.3 open beta, but it still doesn't show HiDPi modes.

Any idea? :)

In the reflection of the monitor I see your couch, a doorway, etc. But I don't see a reflection of you taking the picture.

Therefore, I assume you are a vampire.

nah I am there, if you look closely. ;) Still can't get HiDPi in a resolution I'd like. (non-2x) Tried SwitchResX and I can make 5120x2880 scaled res, but resulting 2560x1440 is 60hz and comes out blurry and out of screen.

With a monitor that large, why would you want to run it at anything other than native resolution?

it's UHD TV, so menus and fonts are way too small!
Then maybe move the desk a little closer. Is there a distance where the menus and fonts are comfortable and your not on top of the tv?

If I move closer to be able to read the native resolution fonts, the screen becomes overwhelming. It is HUGE. :eek: Also my monitors recommended listening distance is 1.5-2 meters, which is why I got the 65 inch TV in the first place, to be able to run it at "retina" resolution.

You have to do what's comfortable obviously but I think this is bizarre... I mean HiDPI is designed for screens with high pixel density (like 4K on a 27" display). Pixel density is certainly not a problem on a 65" screen so it must be too far away.

From what I've read, 40" seems about ideal for 4K at desktop viewing distances... which would be about 24" away (arms reach). Some people get by with 4K on 32" displays at 24" away. So if you double the size of the pixels (as is the case with your 65" screen), presumably your monitor would look ideal at around 36-48" away.

People work with dual 27" displays (which is a combined 54") at arms reach and don't find that overwhelming, but you find this screen overwhelming at 36-48" away?

There must be a distance at which this screen feels exactly the same as working on a 32" or 40" 4K display at arms reach.

And of course, the downside to running HiDPI is that you're throwing away screen real-estate... in this case, for no good reason that I can see.

I will be happy with 2560 x 1440 (HiDPi) or somewhere around that. At 3840 x 2160, things are just too small, as you can see on the picture I uploaded above. I choose eye comfort over screen estate.

kinda SOLVED: Holding down the option key while clicking "scaled" resolution from Display pref, worked. It then shows the HiDPi resolutions.
