- LG LP125WF4-SPB1 (since rev.6) : matte, IPS, beveled PCB corners - best option
- LG LP125WF2-SPB3 : matte, IPS
- LG LP125WF2-SPB4 : matte, IPS
- Samsung LTN125HL02-301 (since rev.6) : matte, IPS
- AUO B125HAN02.0 : matte, IPS - avoid (sometimes doesn't work with the kit when other displays work fine)
- BOE NV125FHM-N62 : matte, IPS - some users reported issues with this model (doesn't turn on until the laptop resumes from sleep)
IMPORTANT: Ask the seller for the exact model that you need!
- Q: Does this mod require soldering?
- Q: Does this mod affect left-side DisplayPort connector?
A: No. The adapter board connects to Dock DisplayPort #2.
- Q: Does the brightness control work?
A: Brightness control does work in dual display mode: FHD display + fake display for brightness control (appears as "Dummy Display"). Otherwise brightness is fixed at 100%. Linux users can apply this kernel patch. BIOS (or coreboot) patch is required to overcome this limitation (I'm working on it sorry, I don't have time for that).
- Q: Does this mod support WQHD displays?
A: No. WQHD requires 4 DisplayPort lanes while the adapter board (and the eDP cable) provide only 2.
- Q: How does it affect battery life?
A: A FHD display itself consumes about as much power as a stock one, but active LVDS interface (which is used for brightness control) consumes additional 1W.
- Q: Can I use docking station with this mod?
A: You can, but the internal display will go blank (and second DVI/DisplayPort on dock will be non functional). To overcome this issue, you can tape a row of DP#2 pins inside the docking connector.
- Q: Does this mod support X220T/X230T?
A: No. It's technically possible to design special version of the adapter board that would fit in tablet, but then you'll need to replace the screen. Which, again, is technically possible, but not really doable.
- Q: Does any of tested displays have PWM/flickering backlight or ghosting/burn in issues?
A: No and no. All tested displays have flicker-free backlight and don't show any ghosting.
- Q: Why is Pepe on the PCB?
A: Smug Pepe depicts the feel I got when I first made FHD display work in my X230. Then it just occurred to me that it would be a nice touch to put Pepe on the board, and so I did.
