Re: Why I'm returning the 4K P50 (with great sadness)

@ibmthink

 

Reading through all those comments here, holding my purchase while waiting for the issues to be sorted out. Just bumped to your post related to the P50 and the dock. Basically that is what I am after.

What I am planning to have is P50 in the dock, with 2 FullHD screens connected using the DP. Lid closed. That is where my still quite decent T520 is sitting and doing its good job.

What are you running? Do you use 2 screens? What resolution? What connection. I suppose there is only one type of the dock for P50, correct?
Just to be sure, I'm not gonna end up in some blind corner not being able to run the configuration I want.
Nowadays, nobody knows :-/

Thanks

I submitted an RMA request for this machine on the 15th. It's the 17th, and I've yet to hear from Lenovo. Does anyone know how painful or painless the RMA process is? When should I expect to hear from them?

@LiborT,

 

using my P50 (6700HQ, M1000M, FHD) with it sitting in a ThinkPad Pro dock, with two screens connected to it.

 

1x Eizo FlexScan L768 (1280x1024, secondary screen, VGA connection)

 

1x Eizo FlexScan EV2450-BK (1920x1080, primary screen, DP connection)

 

Doing two FHD screens should be no problem.

 

Officially, P50 is only compatible with the Workstation dock, but thats much too expensive. Its fits with the Pro & Ultra docks as well (you just need a 170 W charger).

 

Its should be also officially compible with Pro- and Ultra-docks with an adapter, though, as mentioned, it fits without the adapter too.

In response to your question about RMA timing I received my P70 on January 18. Worked on it together with Lenovo support until Feb. 1 then together decided to pack it in as the video card was deemed broken. They set up an RMA and said the RMA department would contact me within 48 hours.

 

The RMA department sent a return shipping label and new order number for a complete replacement within 24 hours. I received my new P70 on Feb 11 and returned the old one at no charge the next day. I live in Toronto.

Thanks for quick reply. I haven't expected anything else, than  it is working. But you know.

But you got me confused with the docks now. OK the Workstation is the one meant to be used. But are you sure, the other ones are also possible?

 

I've checked compatibility matrix https://support.lenovo.com/cz/cs/documents/um006391 and there it mentions Pro and Ultra Dock, but the USB dock/brick (e.g. 40A80045xx). Haven't really seen/used those, but was thinking to rather go with the standard dock (e.g. 40A20170xx) where I can just "click" my laptop in.

 

So you mean, with an adapter, I should be able to use even the "click-in" Ultra dock? Or what did you mean by:

 

Its should be also officially compible with Pro- and Ultra-docks with an adapter, though, as mentioned, it fits without the adapter too. 

 

Thanks,

L

P50 is compatible with both the ThinkPad Ultra Dock and the ThinkPad Pro Dock (mechanical, click in docks). Officially, you need an adapter for that. But I am using my P50 with the Pro dock right now without the adapter, so it obvioulsy works even without the adapter.

Yep. The whole purpose of the "all brand new" Workstation dock is a mystery to me. As far as I can tell, it's no different in anything other than 230W power brick included, and a piece of plastic in new "<3" position that makes inserting the P50/P70 a bit easier.

 

Can run 3 monitors from either too (e.g. 3 * 1920x1200). But all 3 together must not exceed bandwidth of a single DisplayPort (i.e. 1 x 4K * 60Hz or 2 x 4K * 30Hz).

Lenovo P50 (4K) vs Dell Latitude E6520 (1080p) screens at full brightness
 

Just a quick video to show why I am returning the P50 and why I think its screen is particularly unimpressive, even compared to my 4-5-year-old Latitude E6520.

Yes, the P50 is super sharp in 4K. There's no comparison to a 1080p screen when you look up close. The sharpness is very good. But...

1. It's not as bright (forgetting the color temperature differences here). Even though Lenovo says the 4K screen is 300 nits, I found it to be less bright and even more impossible to use outside (even without the sun) than the E6520.

2. Viewing angles are bad. Again, even worse than the E6520. When using the P50, I feel like I'm watching one of those old projection TVs where even sitting perfectly in the middle, you still see shadows and darkness around the edges. It bothers me immensely, especially in 2016.

The 1080p P50 display is supposed to be even worse (250 nits vs 300 on the 4K, worse color gamut and viewing angles, if that's even possible).

There are other issues with the P50, and the screen quality isn't making it very hard to feel bad about requesting a return label (https://plus.google.com/u/0/+ArtemRussakovskii/posts/jP3fowd9mFQ).

P.S. Another annoyance, but one apparently common to all Lenovos - the keyboard backlight turns off every time you close the lid and then doesn't turn back on automatically. You need to toggle it on every time. How annoying is this, coming from the Dell where it remembers the setting forever?

It's very hard to see the difference in lighting when the camera tries to compensate for this, so it would be best if both screens are filmed simultaneously. The only objective way to know of this for sure is to use a colorimeter/lightmeter, but I don't doubt what you're seeing.

 

It looks like typical behaviour of the IGZO IPS 4k Sharp panels. You'll get the same on a new Dell, see for example:

http://www.notebookcheck.net/Dell-XPS-15-9550-i7-512GB-UHD-InfinityEdge-Notebook-Review.156462.0.html . Maybe it is due to the IGZO technology or maybe Sharp saves a bit too much on the polarizers in order to save money and/or keep the panel thin. LCD panels have become very thin the past few years. The 4k panel assembly in the P50 is about 3 mm in thickness.

 

EDIT:

Seeing the review of the E6520: http://www.notebookcheck.net/Review-Dell-Latitude-E6520-i7-FHD-Notebook.53094.0.html

Your video makes a bit more sense now. What I am seeing on the Dell is gamma shifting, brightening the image as the viewing angle is changed. The P50 has no gamma shifting which makes the P50 look "dark". Although I would agree that it has some additional polarizing effect to it that doesn't look good. The Panasonic 3K display also had this "feature", so as I said above, it might be unavoidable.

It is sad after so much waiting. I am still on a T440 with a T450 trackpad just soI have buttons. The trackpad on this is terrible, as are the buttons. I had high hopes for this. Seeing no 4K touchscreen option was a kick, seeing that the 4K screen in and of itself is awful at over $2000 was the dealkiller for me.

 

Maybe in 2017 Lenovo will get it right.
