E545 FHD Display Upgrade

[dcrdev]

Hi All,

I recently bought an E545 with an AMD A10. but I'm not really that satisfied with the screen resolution. I knew what I was getting into - but at the price I paid it was a steal.

I would like to upgrade the screen to a Full HD (1920x1080) display - whilst there is no direct replacement for my model of laptop, I've done quite a lot of research and believe the following display to be compatible: AUO B156HW01.

My reasoning for beleiving this is:

• The screen is used in the Lenovo W530 - additionally there are models of the W530 that use the same LCD panel as the E545 (part number: 04W0430). This indicates that the screen is the same size i.e. depth and will fit in the chasis of the E545.
• According to this post: https://forums.lenovo.com/t5/11e-Window ... d-p/890981 two users have successfully installed the above screen in an E530. The E530 also has a model which uses the same LCD as the E545.
• The E530 uses exactly the same 40-pin LCD Cable (part number: 04W4124) as the E545. Additionally on both the E545 and the E530 the LCD cables are positioned on the left side of the display.

The only remaining question - is the output from the E545 capable of displaying full hd resolutions? The external monitor output and graphics chipset are certainly capable of 1080p - I just need specifics about the internals before I make my purchase.

I'm not concerned about warrenty as after speaking to Lenovo they confirmed that this will not void the warrenty unless a fault develops as a result of the screen upfgrade itself.

Also if there's anything I've overlooked feel free to mention...

Did you happen to find anything out?

I tried to use one of the IPS eDP adapters on my E545 and it didn't work. However, I did just get a W530 with the 1080p panel so I may try again with that sometime soon.

Thinkpad E545 PSREF only shows 1366x768 screens, which puts it in the same league as the T410, X220, and X230-- no FHD via the LCD cable.

Ah, you know what - the E530 had a 1600x900 option. That means the E545 is probably single-channel only at the motherboard level.

That's pretty much the case for any laptop with only 1366x768 screen options (or those that max out at 1440x900). In general, the designers would never build a system board with more LVDS channels or eDP lanes than necessary, especially for budget models like the E series.
