OS X Mavericks 10.9.3 Beta Contains Native 'Retina' Resolution Option for 4K Displays

Apple should release a new 4K - 24-inch display with built-in*Thunderbolt 2 and*USB 3 hubs as well as*SDXC card reader.

 

If you're talking about the Dell Precision M3800 then this is way off.

If you're talking about the XPS 15 then sure, every company has its crap lineup. Like the white MacBook of days past.

 

I'm already aware of the developer tools. There's a difference though between setting an iMac's interface to Retina (x2) and let's say x1,3 to increase readability for my mom.

 

with a 4K iMac i think Apple will surpass the Mac Pro price...so i don't know that they will want that

 

Someone posted earlier that rMBP's older than 2013 wouldn't be able to drive a 4K display.

I have a 2012 15" w/650m. Since I have two thunderbolt ports would I be able to drive a 4K display with multiple inputs?

 

Unfortunately, this issue is far from straightforward. The first hurdle lies with the capabilities of the particular display you're trying to use. Since 4K is still emerging, it's been a bit like the wild west in terms of standardization thus far. The key points, however, are supported refresh rates and input selection. The next factor is whether your GPU can drive that many pixels, and I want to say that for most Macs going back as far as 2008, it actually can. Then there's the matter of what display outputs are available on your Mac, and finally, OS / driver limitations.

Many 4K displays support 30 Hz, single-input operation, and in fact some are entirely limited to 30 Hz. You should be able to drive any of these just fine using DisplayPort (Thunderbolt), HDMI, or an active DP to High-Speed HDMI or DP to dual-link DVI adapter. Mavericks appears to mostly remove the 165 Hz pixel clock limit for HDMI which allows resolutions beyond 1920 x 1200 over HDMI, but this is one of those areas where you may need to tweak your setup with custom resolutions (SwitchResX) or possibly patch your drivers to increase the TMDS clock limit.

In order to manage 4K at 60 Hz, many 4K displays support using dual inputs to drive the display as two separate tiles. You can use two DisplayPort (Thunderbolt) ports, two active DP to dual-link DVI adapters, or some combination of active DP to High-Speed HDMI adapters / built-in HDMI port to drive one of these panels at 60 Hz. Automatic configuration of such displays is far from guaranteed, and may take some tweaking. With Mavericks, Apple seemed to be manually adding certain displays to a sort of configuration white list, and that list seems to have expanded some with the 10.9.3 beta.

The latest 4K displays still use multiple tiles, but can work via a single input by using DisplayPort 1.2 MST, which essentially sends the data for multiple displays down a single cable. The MacBook Pro (Late 2013) and Mac Pro (Late 2013) are the only Macs that support this method, and the MacBook Pros only gained driver support for this capability as of the 10.9.3 beta. Very few displays support DP 1.2 MST, but some that do, such as those from Dell, do not allow dual-input to drive the display as a single surface at 60 Hz. They do, however, work just fine at 30 Hz with a single HDMI or DisplayPort 1.1a input. The Dell UP2414Q in particular is one of the newly supported displays under the 10.9.3 beta, which also hints at possible support for DisplayID 1.3 going forward.

You should be able to drive the ASUS PQ321Q or Sharp PN-K321 at 60 Hz using dual HDMI inputs (with an active DP to High-Speed HDMI adapter to provide the second HDMI input), however it may require OS X 10.9.3 or some EDID / driver wrangling to get it to work properly.

 

This is awesome to hear, but I'll never be able to afford what this news is about haha.

 

Guys,

According to some reports, Late 2013 high-end rMBP with Nvidia 750M card can output 4k @ 60Hz after the 10.9.3 beta release. As you know this is the only Haswell rMBP that has discrete graphics card.

How likely in your opinion the integrated graphics Iris card in the 13'' and Iris Pro in the low-end 15'' Haswell rMBP are capable of outputting 4k@60Hz?

 

Mac Mini 4K

Did they enable the Mac Mini (Late 2012) to use a 4k at retina settings? It is fully capable of doing so and I would like to know.

 

this seems good, but i will, or never, have a 4K display, unless Apple makes their laptops with 4K, iMac', this alone, would be useless to me.

Since Apple's only going with 4K external displays, that puts me out.

 

They should be able to drive 4K @ 60 Hz using dual inputs, but single input MST is still a big question mark. So is single-input HBR2 SST mode for the 13-inch models, at such time as displays supporting it actually become available.

Well, fully capable of 3840 x 2160 @ 30 Hz perhaps. 60 Hz would require dual inputs and might be tricky given the single Thunderbolt port. I believe the HDMI port comes from the HM77 PCH and is limited to 165 MHz (3840 x 2160 @ 18 Hz), thus making it of little use. Apple did use a Parade PS8401A repeater / level shifter though, which will pass up to 300 MHz TMDS signals. I haven't seen anyone confirm that such high pixel clocks are possible from that platform though, and it would run contrary to what's stated in Intel's datasheets. So you'd need a dual-input capable 4K display and a pair of Thunderbolt devices that provide DP 1.1a or High-Speed HDMI outputs in order to do 60 Hz.

Refresh rate aside, the other small detail is that the scaled resolutions are actually rendered at 4x (2x in each dimension) and then scaled down to fit the display. Thus the "Looks like 3200 x 1800" requires rendering at 6400 x 3600. Expect performance from your Intel HD 4000 IGP to be less than stellar. Bear in mind that the initial drivers for this part lacked 4K support entirely, and we're talking about pushing the same number of pixels as 6.25 2560 x 1440 displays.

Running at 30 Hz with the "Looks like 1920x1080" setting would probably be the best option for a 2012 mini, and this should be enabled in 10.9.3. In fact, I think this mode is enabled even under prior versions of OS X.

 

Oh, I think that's the perfect monitor for me! 4K 60hz IPS and 99% RGB for a really affordable price.
I say that because where I live the Thunderbolt display is 41% more expensive than this Dell one. That's the price difference of both from the official store, not re-seller.

I think the only bad part is I'll lose the charger...

Has someone experience with dell display with MACs?

 

Apple TBD for $960 or so:
- Quality display
- no dicking around with EDID crap that may or may not work with the next OS release
- built-in docking for USB, thunderbolt/displayport, ethernet, firewire

Dell 2713:
- $650 for the display, requires EDID override ******** that may or may not work in the future
- only a couple of USB ports for docking.

Add a third-party dock for $200-$300, if any of them are actually shipping, and you get right up there in the ATD price range, with a lot less convenience and a lot more FUD.

 

Dang, what terrible timing. My 30" ACD just died tonight. I wish there were a clear successor to replace it with.

 

I'm actually having trouble finding the current ones at the most popular Finnish or Swiss stores... typically this points to an impending release. Here's hoping for release in the next few weeks!

 

There is still hope they reintroduce the 17" MBP with a 4K screen... I'd buy that in a heartbeat!

 

I really wish Apple would do this! I'm missing my 17" screen size but cannot go back from retina now

 

I bought a used 23" ACD that was DOA after I got it home. Randomly I gave it a good shake and it started working again. I have to do it every so often.

Give that a try.

Agreed, the ATDs have great value.

I don't really want 4K/UHD in the same form factor as the existing 27". 30+" please, ideally 39+", otherwise I'm fine with the current product (with a price drop or port spec refresh). Maybe this pairs up with iTV rumors or they share a display.

Not sure about you but I want the real estate when I'm at my desk, not the clarity over a certain level. Defining retina means that you don't push pixels over that viewing distance. And I'll take a good display over a high resolution one any day.

2560x1600 wouldn't be a bad refresh, give it a chin and make it as tall as the iMac.

The thing that would be a category killer would be resolving the ability to daisy chain another (non-Apple) display off the TB port. This would enable MBAs and MBPs to run multiple displays and everyone to have a simpler "docking experience" where you just plug in magsafe and TB. Updating to TB2 will make this less of a system hog.

 

Hello,

I just got a LG UHD TV, and it sees resolutions up to 4096x2160@24hz, but I can't seem to get the correct HiDPi mode. Only 960x540 shows up as HiDPi mode.
