Inspiron 7567 Components

I'm considering purchasing an Inspiron 7567 but Dell is unable to provide exactly which components the computer will have. I guess they install whatever parts they have at the time, but I would like to know what I'm buying.

The laptop comes with a 128G m.2 SSD and a 1TB 5400rpm hard drive. I know Dell is fond of Hynix memory, any ideas as to what brand and model m.2 SSD and hard drive comes with this computer?

How about the display panel? It's an FHD IPS display, any information on the brand and model number of the LCD panel? LG seems to pop up pretty often. Some are 72% NTSC color gamut, which would be fine, some are 42% NTSC, which would not be.

Any info on these components?

 

NTSC is largely irrelevant. It's an old and outdated standard. What you should be most interested in is brightness and sRGB. As for those, brightness should be around 200 nits and sRGB in the mid-50%s

 

Good to know. I'm using NTSC color gamut because it's the most accessible comparison point for these displays. Knowing the actual display panel to see the specs would be real helpful.

 

The components will vary based on availability, so they simply cannot guarantee what you'll get.

The RAM you'll get is likely to be SK Hynix, as that's what I got (and what others got).

The SSD might be a SanDisk X400 (it's what I got).

The FHD panel is either an AUO or LG panel. The LG panel you'll get is the following:

LP156WF6-SPK1
sRGB: 67%
AdobeRGB: 51%
NTSC: 49%
Brightness 300 nits (though it drops to around 270 or so after calibration)

The AUO is:

B156HAN01.x (not sure on the exact panel revision)
I personally haven't calibrated/tested it (it was reported by another user), but it's likely to have similar specs to the LG panel.

You will not get a 72% NTSC/99%sRGB panel on a machine at this price point. What you can do is order the (very good) LP156WF6-SPB1, or the AUO B156HAN01.2 off ebay and install it yourself. Replacing the display panel on this laptop is very easy - 15 minutes and you're done.

While NTSC isn't very relevant, panels that cover 72% NTSC typically cover 99% sRGB, while panels below 50% NTSC typically cover around 65% of sRGB. So in a sense, it's just as valid a way to identify the colour coverage of a panel as quoting the sRGB would be. They go hand in hand.

And a display brightness of 200 nits doesn't even exist in IPS panels these days. They all pretty much start around 240 or so.

 

Thing is - I've seen quite a few 72% NTSC screens where the sRGB coverage is about 70-80% - we've actually discussed the colours in an older topic and that correlation seems to be largely inaccurate nowadays.

 

Really? In that case it really is irrelevant to quote that coverage nowadays then. But then again, we're now seeing crappy IPS panels, where before there were none. Back in the day, if you got a machine with a FHD IPS display, it was by default a good one, as they simply didn't make any bad ones. They were a premium product.

The FHD IPS panel is now the new 1366x768 TN panel - a place where OEMs will cheap out as much as possible, since people buying those seem to be less and less demanding in terms of the quality of the panel they get.

 

If information is limited about specific panels and all you have are the sRGB coverage specs, a 75% sRGB panel must be better than a 45% panel.

 

You can't really compare sRGB, Adobe RGB and NTSC directly. They're all used in vastly different scenarios and calculated in a different manner.

 

I really don't know that much about display panels so I don't know the details of these measurements. What I mean is that if the only common information you have is an sRGB percentage, the higher value would mean a better panel than a lower value.

 

For regular usage, yes. sRGB is most common in multimedia and general use on the internet.

 

Yes, because the colour spaces do not completely overlap.

Made some pictures in order to clarify this NTSC vs. sRGB business; Panasonic VVX16T010J00 vs Samsung LTN156HL02.
