LG yesterday released a new version of its UltraFine 5K Display with USB-C connectivity, allowing it to be used with 2018 iPad Pro models, but Apple has since confirmed that the iPad Pro cannot take advantage of the full 5K resolution.


In a new support document, Apple says the UltraFine 5K is limited to a 4K resolution of 3,840×2,160 at 60Hz when connected to 2018 iPad Pro models via USB-C. The full 5K resolution requires a 2016 or newer MacBook Pro, a 2018 or newer MacBook Air, a 2017 or newer iMac or iMac Pro, or a 2018 Mac mini.

The new UltraFine 5K Display is available to order for $1,299.95 on Apple.com. Like the previous model, it also supports Thunderbolt 3, with up to 94W of power for pass-through charging of any Mac or iPad connected to the display.

The new display has the model number 27MD5KL-B.

Imagine having the most svelte and streamlined tablet on the market connected to a fugly bezel-thick monitor that looks like it came out of a ca. 2007 accounting firm. The resolution would be the least of my concerns.
While using it, are you going to look at the screen or at the bezels? The resolution is imho more important.

The monitor is not a beauty, though.

So to be clear the previous generation 5K display was unable to handle an iPad Pro 2018 connected to it? Can anyone verify this? I've read the previous generation 4K display worked fine with iPad Pro 2018.

The problem is whoever decided the camera is mandatory. But even then, they could have trimmed the bezels overall or make the bottom bezel to match.

it has not enough bandwidth , since tb3 is still under Intel license
www.displayport.org states that technically, USB-C can now support 5K resolution.

https://www.displayport.org/displayport-over-usb-c/


DisplayPort leverages the Alternate Mode Functional Extension of the USB Type-C interface, and shares similar electrical characteristics with USB 3.1, allowing use of common system elements.

  • Video, SuperSpeed USB and power, all on one connector
  • 4K @60Hz 24-bit color (without compression) with simultaneous USB 3.1
  • 5K (5120 x 2880) display support without compression with simultaneous USB 2.0
  • Support for BT.2020 color space, HDR, and HDCP 2.2
  • 8K x 4K display support with use of 4:2:0 pixel structure (good) or VESA Display Stream Compression (better)
  • High-end multichannel audio support
  • Backward compatible with VGA, DVI, and HDMI 2.0 with CEC using plug adapters or adapter cables
  • Extensible packet-based data structure


It's just that the 2018 iPad Pro models or the 12" MacBooks can't do it.

However, simultaneous 5K video plus USB support over USB-C is limited to USB 2.0. To get simultaneous 5K + USB 3, you need to use Thunderbolt.


So to be clear the previous generation 5K display was unable to handle an iPad Pro 2018 connected to it? Can anyone verify this? I've read the previous generation 4K display worked fine with iPad Pro 2018.
The previous 5K display is Thunderbolt 3 only. It didn't work at all with the iPad Pro. The previous 4K display is USB-C. The new 5K display accepts both Thunderbolt 3 and USB-C inputs.

No surprise. iPad is USB-C, not Thunderbolt. I like my (older) LG 5K TB display.

It is a bit of a pain under Windows since there are no brightness controls. Thankfully, the default brightness is reasonable for my work environment.

Would I prefer it be an Apple display? Yes. But I've had no complaints with it.

I'm always amazed that this day and age we still get ugly products like this one. If Apple collaborated with LG on the monitor why couldn't they help them with design? The whole thing is super ugly, if it wasn't I could see myself buying one but this is not gonna be on my desk.
Sad to see companies still ignoring the most basic thing such as design. Design is what sells - is it really hard to understand that? Especially if you are aiming for Apple customers.

So, $1300 for a 27" 4K monitor? LG is drunk off of the Apple Kool-Aid. They should have renamed it UltraFine 5K*.
