I just unboxed and turned on my P53 w 4k OLED display. It seems that what I think is the digitizer for the touch screen has made the beautiful looking 4k panel underneath it look pixelated and strange because of the crosshatch pattern that is layed over it. This is ridiculous in a computer that I paid $6,000 for. Is there anything I can do to fix this panel? It really affects the quality of the display! It looks like an old 720p monitor. I'd almost rather have a non-touch clear glass option that could replace the digitizer if that's what it is. Picture attached.

Is the cross-hatch pattern visible to you at 18" distance, or is it visible just to the camera? Others, myself included, have noted horizonal dots/lines in the OLED display, but not the cross-hatch that you show in your picture.

I've lit the panel from the side with a flashlight to emphasize what i believe is the digitizer pattern that is causing the distortion of the screen. The distortion renders as dots and horizontal lines that kind of "shimmer" with different colors much like you describe. It is my belief that the digitizer is what is causing all this. If that's the case, id GLADLY give up the touch feature to see the actual screen that I paid for.

I believe that the dots/lines are caused by the subpixel arrangement of the Samsung OLED panel. There is a bit of negative space between the blue pixels that could be the cause of the dots/lines. I can see them if I look closely, but at a normal viewing 18" distance, the lines mostly disappear. I've never seen the cross-hatch diamond pattern in any screen display.

Interesting about the subpixel arrangement. I still really think this is a main product of the digitizer striations. It is EXTREMELY annoying. To have a panel of this quality and have it be completely negated by this poor design is pretty outrageous. I will definitely be in touch with Lenovo about this on a daily basis if nessasary until something is fixed.
I should also note that this is my SECOND P53 so far. I orginally ordered the non-touch UHD panel which looked absolutely fabulous until permanant splotches appeared in it and I had to send it to the depot. Well, of course the non-touch UHD panel was on heavy back-order so I opted for a refund and got the OLED to save time and also since it was ostensibly a better monitor that wasnt available on my original order.
I'm not letting them get away with this. I bought an ISV certified workstation for art and to have it look like a $129.00 chromebook display is just outrageous.
Does anyone know an engineer or designer at the company that I can speak to directly?

The digitizer has two components: A discharge layer which is the wire grid in the front to allow for use of fingers and a capacitive layer behind for a pen device. The pattern that you are showing in the posted picture is the front component and I don't believe that without shining a strong light obliquely on the panel, that you would even see this at normal distances.
I have two multi-touch units in addition to my P53 in my inventory: P1 Gen 1 4k UHD LCD IPS panel (cannot see any grid/lines/dots); X1YogaGen2 WQHD OLED panel (cannot see any grid/lines/dots). Again, I believe that what you are seeing under normal conditions on a 100% white (or continuous color) background is an artifact of the subpixel arrangement (which is different from my 14" OLED panel on the X1YogaGen2). Interestingly enough, at this juncture, I can't even see the lines/dots on my P53 anymore this evening even when I'm 4" from the surface. Maybe things have to burn in with use a bit. I have about 50 hours of use on the system at this time. BTW, the same panel is used on the P1 Gen2, X1 Extreme Gen2 and the P53.

I just measured how far I am from the screen. My face is 22" away (i measured) and I can see the distortions and "screen door" effect clear as day. Regardless of what is causing it, these panels should not have gone into production in this config. I'm dreading video and photo production work in this thing, it can't display a pure white field! How am I supposed to feel confident in my work?
I can see being happy if they agree to swap my display out to the non-touch LCD 4K when they are available again and refund me the nominal difference in price.

OK, I had my panel X-Rite calibrated at the factory and I have different white point temperatures that the display can exhibit. Right now I am using the DCI-P3 calibration for my normal work and video playback (White Point: x:0.3127, y:0.3290 Gamma 2.6). Swapping the display will probably entail a new system.
