P53 (OLED vs. UHD, RTX 5000 vs. RTX 4000)

2019-08-13, 1:17 AM

Hi, I have some questions about the UHD and OLED configurations mentioned in:

http://psref.lenovo.com/Product/ThinkPad/ThinkPad_P53

 

1. The regular IPS UHD model has HDR 400 while the OLED one has HDR 500. In practice, how does it affect user experience?

 

2. The regular IPS UHD model has 500 nits but contrat ratio 1200:1. For the OLED model, it only has 350 nits but super high 100000:1 contrast ratio. Does higher contract ratio makes up the lower nits of the OLED model? How is the battery life of these two models?

 

3. The non-touch models start at 2.5kg while the OLED model starts at 2.9kg. What is the weight of the 4K UHD with RTX4000 8GB and that of the OLED with RTX5000 16GB? Having OLED and touch adds 400g more in weight?

 

4. What is the speed, battery life and noise of the OLED RTX5000 model vs. those of the regular UHD RTX4000 model?

Considering that the Sales page says that the OLED-equipped machines are "Coming Fall 2019", I don't think anyone can give you the answers you seek, now.

So, there is no way to get such data from Lenovo?

Well... this is a peer-to-peer user community forum, so the data by/from Lenovo isn't likely to be posted here.

 

You can keep an eye on the PSREF for updates on some things, but what you're asking about are essentially real-life impressions. Until machines are in people's hands, you'll need to wait, I guess. How long can you wait before making a purchase decision? If your timing window is short, you may need to decide before info is available.

 

Regards.

400 g seems like a lot, but there is certainly an extra layer of of rigid material in the front of a touch screen.  That is where the little matrix of wires for the digitizer live, and the rigid smooth surface is why touch screens are glossier.  I can imagine that being OLED would also add weight.  The layer with the LCDs in a "normal" screen is VERY thin and light.  The OLED screen needs to light every spot individually.

Thanks Rich. Is the OLED screen worth the extra weight and wait? In general, does OLED screen consumes more or less power? I heard that the burn-in issue should have been fixed. Hope that is reall the case.

I want to see one before I decide.  I have never had an OLED screen for any period of time to be able to compare battery life. Weight is less important to me, but it might be REALLY important to you. The cost might be "worth it" to you but not to me.  (Also, until it is for sale, there is no way to know the pricing.  It might be worth it at $19 but not worth it at $1,900)  I will say that the first time I saw one at a trade show, I just stared at it for about 20 minutes.  In theory, an OLED screen should use less power, especially if you use a black background because the black areas don't need to be lit.  In practice, I have heard that previous versions used more rather than less power, so I don't know.  There is no way to know about the burn-in problem until they have been used for a while.  One more thing:  I have always preferred a touch display on laptops and the OLED seems the only high-res, touch option.

I ordered a P53 with OLED display, RTX5000, XEON processor. The OLED display is a multi-touch unit with anti-glare and anti-reflective coating on the panel surface. Once you've used a system with an OLED display you'll never go back to an standard LED display again. I don't think that the power consumption on a P53 with 4K display is a significant difference in run-time. I also own an X1 Yoga Gen2 with an OLED panel for two years now with no issues on burn-in. My desktop default is a black background, but I occaisionally use a picture instead.

When will yours arrive? P53 is already heavy. Adding an oled screen would make it heavier. After using glodsy screens for so many year, I feel kund of strange looking at matted screen.

Might receive the unit mid-Oct. The weight will increase a bit, but that is to be expected. I'm more concerned with image quality and the size of the system. I currently own a P70 which is very non-portable because of the weight and size. The P53 will fit in my Tumi bag with ease.
