[SOLVED] How to find out laptop screen hardware?

ondoho · 11-01-2019, 03:01 AM

So, I got a ThinkPad x250, yay!

According to this, it comes in many different variants (more than the three shown in the table).

I would like to find out what sort of screen this laptop has, namely an IPS or a disappointingly mediocre TN.
The resolution is 1366x768, the processor is a Core i5-5200U, RAM is 8GB.
That would point to the "medium" model with an IPS, but I see nothing to confirm this. Not on the machine; I'm guessing the previous owner must have removed a sticker from the bottom.

How can I find out the screen type beyond guessing?

I tried

Code:

lshw -C display
xrandr -verbose
hardinfo

Only xrandr gives something beyond the resolution - an EDID for example.
Could that be used to define the hardware used?
Or what?

edit: tried

Code:

dmidecode

too.
That gives a lot of info, but nothing that obviously talks about screen type.

edit2:
OK

Code:

dmidecode | grep -A8 "System Information"

gives the sort of detail I'd expect on a bottom sticker, but still nothing about the screen itself.

I don't know if you have already tried something like this: https://forums.lenovo.com/t5/ThinkPa...S/td-p/1372695

hwinfo --monitor won't tell you what you want to know?

Ah, that, combined with the information from 'dmidecode', led me to this page.
It is an IPS panel (and just looking at it at an angle confirms that).

I didn't know about that one, so thanks, but no, it didn't - at least not unencrypted

PS: I honestly did not think of searching "thinkpad IPS or TN"...
