Display on W530 - 95% wide gamut?

People have requested to change the thread name to "Lenovo FHD display discussion". That's ok with me. can a mod can do it?

 

Usually when they say 95% gamut they mean of the NTSC colorspace not AdobeRGB. Where is it listed that it is AdobeRGB and notebookcheck.com doesn't count as I don't think they do any real tests (may be wrong on that)

 

yes it's ok . Can you do it if you're a mod?

 

Color gamut refers to the various levels of colors that can potentially be displayed by a device. Various standards govern color gamuts. The three standards frequently cited in relation to computers are sRGB, AdobeRGB, and NTSC.

To quantify the various color gamuts in terms of their relative range of color of narrowest to widest would be: sRGB < AdobeRGB < NTSC.

The FHD display panel used in the Lenovo ThinkPad T/W510/520/530 is produced by AUO (AU Optronics). The product identification code is B156HW01 V4. This panel is also used in certain notebooks by MSI, Clevo and Sager. Its glossy twin is used in the Dell XPS 15 L502X.

I have seen "95% color gamut" and "97% color gamut" stated in relation to the AUO B156HW01 V4. This is understandable as the former implicitly refers to the AdobeRGB gamut and the latter the NTSC gamut. Nowadays, because of the popularity of Photoshop among graphics professionals, the AdobeRGB color gamut tends to be the norm.

 

Maybe the mod can just lock the thread. It's ridiculous at this point.

 

That's ok with me (the OP)

I think we covered everything about the "gamut" of the W530 but I wish people would talk about the what the dithering is like and if they have an IPS desktop monitor maybe they can post side by side pics.

Like I said before if you are just doing CAD, spreadsheets, docs, web browsing, or many other things you probably can live with a 6-bit-per-pixel screen but if you have to do photo processing away from your desktop you definately DO need an IPS screen that's 8 or 10-bits per pixel.

 

Is this display used in the T530 as well? Also, what do you think of this display is it worth the extra $?

 

Yes. The T530 and W530 are the same in many aspects.

To me, it's a valuable upgrade. (Some people consider 1920x1080 resolution too dense and worry that texts and icons are too small. If you set 125% magnification in both Windows and your favorite browser, things appear quite nice. I'm typing this one a FHD screen right now.)

If the upgrade cost makes you hesitant, the HD+ 1600x900 display is quite good -- not "dull" and "griddy" as the HD+ screens on the T430(s).

 

The 1080p screen is very good.

But, as is usual with upgrades, the price Lenovo wants for it is quite steep. If you don't mind unscrewing about 9 Philips screws, AUO B156HW01 V4 can be purchased on ebay around $100+shipping. Selling the old one on ebay will recover most of the cost

 

Hmm, elsewhere for $86 + shipping: exact, genuine, brand new, received in 2 days.

3 front screws, 4 corner screws, 4 side screws. That's the easy part. The 40-pin connector is so delicate.
