Hi everyone.
Really I wish it was possible to buy all the components of a laptop separately and put it together yourself. As that's not possible I'll make the most of what is available.
The plan right now is to buy a Lenovo ThinkPad E540. However, there is no option for an IPS screen. I was thinking of getting one with the cheaper 1366x768 screen, and swapping it out for a 1920x1080 IPS screen myself. It's often warned by the screen sellers to only replace a screen with one of the same resolution. Can anyone let me know if I should heed their warnings, or is it fine to replace the 1366x768 panel with a 1920x1080 panel on the E540?
Reasons I've seen given:
1. Hardware may struggle with higher resolution.
2. Video cable may not support increased resolution.
3. Port to screen may not output to higher resolution.
4. EDID on the panel may not be compatible.
The GPU and CPU will be more than enough for 1920x1080.
Both the 1366x768 and 1920x1080 E540 use a 30 pin connector. The difference seems to be that one plugs into the bottom left of the panel, and the other the bottom right. See HERE for details.
Do I have it right that these are both eDP displays? If that's the case, a 1366x768 E540 would use a eDP port so should be able to output 1920x1080. Or am I mistaken?
As for EDID compatibility; if they both are eDP then they should both be using EDID structure v1.4, right?
On the Lenovo online shop (Ireland), the price of the upgrade from the i3-4000m to the i7-4720mq is about the same as just going with the i3-4000m and buying a brand new i7-4702mq separately! I don't know who would want to buy a i3-4000m, but I'd have it spare anyway. My question is, do Lenovo solder the CPU to the motherboard in the E540? I'm finding the i7-4700mq (47 W) are cheaper than the i7-4702mq (37 W), plus the extra 0.2 GHz doesn't hurt either. May not be worth the batter cost though. Is it a bad idea to use a 47 W CPU when a 37 W was intended?
I'd love to hear your thoughts on this.
