15,6 inch mod in T420

#1 Post by t420poklop » Thu Dec 20, 2018 2:24 pm

I have t420 with FHD mod and I absolutely love it. I was wondering, if would it be possible to do modification with 15,6 inch display on t420; something similar like t230/t330? The converter board for FHD IPS display 14 inch mod for t420 has same connector as 15,6 display. Will it work?

I doubt it will be big enough.

The efficiency of two screens equally sized with equal numbers if pixels are equal. The time spent by a 4:3 user complaining about 16:9 is proportional to the inefficiency working with a 16:9 display, therefore the amount of useful work extracted is equal.

The same people do in fact make conversion kits for the 15.6" LVDS laptops to put in IPS 15.6" eDP screens. In that case the purpose of the mod is to get IPS screens, not just to go up in resolution, because TN FHD screens already exist and are very good per se.

The problem with putting a 15.6" in a T420 is that 15.6", and 15.4", screens are physically too big to fit inside the T420 and other 14" laptops. See: https://old.reddit.com/r/thinkpad/comme ... t_t410_15/ Someone put an IPS 15.6" LVDS screen inside his T410... well inside maybe isn't completely accurate.

Yes, IPS 15.6" LVDS screens already exist but the display connector is in too different a location for it to be practical to put inside the T510, T520, etc..
