I've received my 6" 1440p screen that I've purchased for doing some VR experiments on PC. It comes with a small board with Micro-USB IN for charging and HDMI IN. It's a really good SHARP CG-Silicon screen with a perfect image quality.
I've tried this setup with my GPD Win for fun, and it does work quite well! I've set the scaling in Windows 10 to 200%, so it looks like a 720p retina display - exactly the same layout as the Win's display, but with ultra sharp details, and on a 6" screen, the image is bigger and is perfectly readable / usable - way better than on 5.5".
Tested a bit of retro games in RetroArch: Scaling + CRT shader looks perfect!
There are a few issues for those of you that could be interested to get this:
- The multi-screens setup need to be set to extended, as the Win's screen needs to be on for the gamepad to still work - so I'm basically doing multi-monitoring on a handheld
- The board I have only support 50hz.
- It's an ugly setup - though it could be fixed with short cables and a 3D printed case.
- It will probably drain the battery fast, not tested enough to tell.
Though, this allowed me to re-think about the best resolution for the Win 2. I previously thought that 720p would be perfect, now I think that 1440p (which is 4 times 720p) would be even better. Of course you could still run demanding games in 720p and they will still look great - just like PSP games on the Vita (the Vita is 4x the PSP in resolution).
: For the Win 2, please consider a 6" screen with a resolution of either 720p or 1440p.
For those interested in this setup, here's from where I got it, the whole package is around 100 euros:http://akizukidenshi.com/catalog/g/gM-11968/
