Answering a couple of prior questions:  TB3 is 2 lanes; and all displays for T490, T590, and T490s are 8-bit 262k color depth or higher.


Not to be silly, but isn't 8 bit = 16.7 million colors? 2^8^3?

 

6 bit would net 262k.

Re: T490 & T590 - First Look (review, benchmarks)

These new units are now available from lenovo online shop but the customizations are still not showing all options. Only 2 cpu options, cannot configure the advertised "up to 48gb" memory, only 3 display options, etc.

 

I'm planning to get my first ThinkPad and I don't know about the previous releases, so I have a few questions for long time users.

1. The announcement state that the availability will be around June, but at what timeframe will they provide the full customization options?

 

2. Drive Options
256GB Solid State Drive, M.2 2280, NVMe, Opal, TLC (+$40)
256GB Solid State Drive, M.2 2280, SATA, OPAL 2.0, TLC (+$40)
512GB Solid State Drive, M.2 2280, NVMe, Opal (+$170)

- to my understanding, nvme is better than sata, then why the 256GB options have the same price increase?
- is Opal a Lenovo proprietary drive? Can I replace it with third party ssd like Samsung NVME Pro?

3. GPU / Display options
- I'm thinking of getting the MX250 for occasional photo editing. Is it possible to disable the dGPU, and stay disabled after reboot, so it does not drain battery?
- From all the possible display options, I'm leaning toward the Low Power IPS 400 nits options. Any idea what impact will the "Low Power" option be in terms of color quality (again for occasional photo editing)?

I'm newly back to ThinkPads, but I'll do my best to answer:

 

2.  Opal is an industry standard for self-encrypting SSDs for data security.  I don't believe Lenovo makes any drives themselves, but uses drives from Intel, Samsung, and in case of these two laptops, Toshiba.   As there's a significant performance difference between PCIe and SATA interfaces, you'd want to carefully consider the full specs of both drives.  A non Opal SSD drive would also work, although Samsung 960 and newer drives also support Opal. 

 

3.  When equipped with discrete graphics, it switches dynamically between the two graphics processors depending on the graphics work being done, to maximize performance and battery life.  There are probably ways to disable the discrete graphics altogether to maximize battery life further.

Looks like customizeable versions of the T490 and T590 have now shown up on the Lenovo US website.

Re: T490 & T590 - First Look (review, benchmarks)

I want to buy the thinkpad 490S. On lenovo's website in italy I can choose these two display :
14" FHD (1.920 x 1.080), IPS, 400 nit, antiglare
14" FHD (1.920 x 1.080), IPS, 300 nit, antiglare, multi-touch

Which is the best display and which is the low power display ? I would like the multi-touch display but it have only 300 nit the other have 400 nit then it is more bright. I want the display that consumes less...

Hard to say what the specs are in Italy. In the US, the 300 nit FHD touch display appears to be a carryover display from the T480. Low gamut, old tech. Hopefully some of this information is relevent to you.

 

400 nit FHD displays are the newer ones, but there are two:

Low power (800:1 contrast ratio)

Privacy (1000:1 contrast ratio)

 

Both claim ~100% sRGB (which is good, compared to the 300nit FHD panel).

 

In the US, the Low Power display is the only one currently available with 400nits (Privacy version may come later), and it also has to be paired with the IR camera.

 

 

 

It should be noted, I have no clue if Italy/EMEA has different specs than the US does. PSREF is currently down at the time of writing.

Hi ! Thank you for your answer.

Then I must search the 400 nit FHD display Low power (800:1 contrast ratio) because it's the best for the consumes ? The Privacy (1000:1 contrast ratio) version consume more?

 

I can insert into configuration also NFC, Sdcard reader and Ethernet ut these things make the PC thicker and heavier?

AFAIK, ethernet (RJ45) jack should already be built in and integral to the T490, as is a microSD card reader. NFC is a small PCB inside of the laptop inbetween the battery and the palmrest. Since I doubt Lenovo is redesigning the chassis around that feature (they have not in recent years), it should not increase thickness of the laptop. Weight increase from NFC would be measured in <20g, though that is an estimation from myself.
