Verify: Drive 4K UHD or QHD Display Monitor TV at native resolution with range of old & new Thinkpads?

Has anyone/ Is anyone used Thinkpads with a 4K UHD or QHD Display?

This person made a post about testing a 4K Monitor with tons of Thinkads. I was wondering how legit is this information?

ThinkPad compatibility with 4K LCD (ThinkVision Pro2840m)

I just recently received my first 4K LCD (ThinkVision Pro2840m) from Lenovo Australia, and i have to say this is one of the coolest monitor that i have ever played with in the recent years. But i will defer the actual detailed review of the ThinKVision Pro2840m to another day, this post is merely a short summary list of all the ThinkPad laptops (with Displayport/HDMI) that i have tested with the new ThinkVision 2840m. I have omitted some models from the compatibility list, as i do not own these models and i could not test their compatibility with the new 4K LCD. Following is the list of machines that i have tested, which shows support for the 4K resolution of the new ThinkVision Pro2840m (@30hz):

Thoughts? Is this legit info?

Thanks. Is this person part of our forum?

Can someone confirm this or some of these please?

Can fellow members test & share their experiences?

PS: When posting back do share similar details if possible.

- Specific Model/ Video Card
- DP + version / HDMI + version
- Resolution @ XX Hz / Frequency
- If possible: Display/ Monitor/ TV Model

ThinkPad W701ds and W701 with Nvidia Quadro 3800m GPU
ThinkPad X201 with Intel HD GPU (must set the 4k LCD to DP 1.1 mode)
ThinkPad X201s with Intel HD GPU (must set the 4k LCD to DP 1.1 mode)
ThinkPad X201t with Intel HD GPU (must set the 4K LCD to DP 1.1 mode)
ThinkPad X220 with Intel HD 3000 GPU
ThinkPad X220t with Intel HD 3000 GPU
ThinkPad X230 with Intel HD 4000 GPU
ThinkPad X230t with Intel HD 4000 GPU
ThinkPad X240 with Intel HD 4400 GPU
ThinkPad T410s with Intel HD GPU (must set the 4K LCD to DP 1.1 mode)
ThinkPad T420s with Intel HD 3000 GPU
ThinkPad T430s with Intel HD 4000 GPU
ThinkPad T430u with Intel HD or Nvidia 620m GPU (DP only)
ThinkPad T440 with Intel HD 4400 GPU

ThinkPad T440p with Intel HD 4400 GPU
ThinkPad T510 with Intel HD GPU
ThinkPad T520 with Intel HD 3000 GPU

ThinkPad W530 with Nvidia Quadro 1000m/2000m GPU
ThinkPad W540 with Nviddia Quadro K1100m/K2100m GPU
ThinkPad X1 with Intel HD (only Displayport)
ThinkPad X1 Carbon with Intel HD 4000 GPU
ThinkPad X1 Carbon (2014) with Intel HD4400 GPU (HDMI + DP)
ThinkPad Yoga Intel HD 4400 GPU (miniHDMI + Displayport)
IdeaPad Yoga 2 Pro Intel HD 4400 GPU (microHDMI)
IdeaPad Yoga 3 Pro Intel HD 5300 GPU (microHDMI)
Also, to note that there are a couple of ThinkPads that are capable of supporting 4K at 60 hz refresh rate. These machine models are:

ThinkPad W530 and W540 using Displayport
ThinkPad or IdeaPad with Intel HD5000 GPU
There also some older models of ThinkPad that i have tested, which does not support the ThinkVision Pro2840m LCD’s 4K resolution, and won’t work with the monitor when it is in DP 1.2 mode (so you have to switch the LCD to DP 1.1 mode).

ThinkPad X200, X200s, X200s
ThinkPad X301
ThinkPad T500 with Intel 4500MHD GPU
ThinkPad R500 with Intel 4500MHD GPU
These ThinkPads would only work with the ThinkVision Pro2840m when the Displayport is switched to the DP 1.1 mode, and they would only support the LCD at 2560×1600 resolution.
