Re: OLED issues on the P53 / P1 Gen 2 / X1 Extreme Gen 2 ?

Since the panel can't be making things fade, it must be a sensitivity in my visual acuity that allows me to see them. Sort of like a sensitivity that some have for PWM. 


 

 

I'll try my luck with the OLED screen then. The return period is extended.

 

 

 

Just another quesiton on the OLED, are you able to use fully dedicated mode (turn off the Intel Graphics) in the BIOS and drive the OLED panel with the Nvidia Graphics alone?

 

 

Because I have an Alienware 13 with OLED display and only able to drive the panel using Hybrid/Optimus Graphics (using Intel GPU). It has problems with some rendering applications.

Yes, you can switch the display gpu in the BIOS  to the NVIDIA card,

I have had no issues with my OLED screens. 

So far, I've had 2 P53 laptops. Both had great screens.

 

I would recommend the color calibration for $10 and the lenovo pro pen for $30.

 

Worth it for $40, in my opinion. 


You do have the 4k OLED touch screen, correct? It's interesting that you cannot see these artifacts and that many others immediately can. I also find it curious that the same Samsung panel is used by other manufacturers without the touch panel and there has been no notice of these artifacts by any reviewer. All of this appears to be Lenovo unique. It's too bad that such a quality screen is saddled with this behavior.

I do have the OLED with the color calibration and the pro pen. 

 

It was one of the major reasons I decided to keep the P53 over the MSI GE75. 

 

I can see very small dots if I get around 4 inches away on a white background.

 

The problem is, I don't typically see white backgrounds outside of using notepad. 

 

My Firefox uses Dark reader. Gmail, YouTube, Windows, Krita, Gimp, office 365, and visual studio have dark modes that I use.

We received first batch of P53 for our P53 people with OLEDs

Looks gorgeous to me; I only spent an hour or so with one, but couldn't' see any anomalies

I wasn't purposely looking though, didn't do 4 inch away thingy too; lil too close for me :-)

OK, I don't look at my system from 4", but when I first was setting things up, I looked at the screen (like I always do for a new machine) to see if there were dead pixels, etc. So, The dot/lines were apparent in short order. However, I don't use white backgrounds, my themes are dark mode where possible, and the color redition is awesome. However, some people are using the P53 for publishing and video editing and these artifacts create issues with regard to color and texture. I can't see these things in my normal viewing distance and programs.

Out of all the 15.6 Samsung OLED screens, the P53's is the only one I've heard anyone mention dots/lines.

 

It leads me to believe that it is the Wacom pen layer. The razer has a touch OLED screen and it's only complaints are color shift when going from 100%-lower brightness, and out of the box color accuracy (which could be related).

 

Personally outside of this topic I would have never thought there was an issue to began with. It isn't noticeable to me at all, though I do wear glasses and I have been focused on other areas of the laptop.

 

Like coilwhine when the gpu reaches high clocks underload. Both my P53's had/have it. A couple of reviewers even mentioned it.

 

So I'm not saying the OLED issue is a small one or not important, just not something that has commanded my attention yet.

I've heard about coil whine, but never have experienced it on any system that I've owned. I wonder whether it's because my P53 and P1 are using XEON CPUs? Everyone else that has owned these systems has complained about the noise, but all of those posters did not have a XEON CPU. Thoughts?

I don't think its the CPU.

Go to https://youtu.be/vHEPbVQMdLs

 

It is the GPU when under heavy load but high clocks. This is running 3dMark Skydiver benchmark. This is my P53.
