Do you guys think its not a fake?

[Lphillimore]

Not a fake just misleading.

Description says it supports resolution from 480x320 to 1920x1080.

Its not a high definition display, however. Your output resolution will be 480x320.

There's a difference between supporting HDMI inputs of 1920x1080 and actually displaying them.

So the number of "physical" pixels is only 153600 (480x320) right?

I also posted this one here a few months back:

https://www.alibaba.com/product-detail/ ... 05967.html

I assume nobody tried to use that yet? Especially since nobody shown interest. It has a perfect Game Boy (Color) screen ratio btw (but not pixel perfect, its 7.5x larger in terms of pixels). I also understand that one has its own technical challenges.

Or any other small (2-4") display over hdmi for that matter. But I know they are almost non-existent.

I got this screen from Epathdeals /epath china from amazon. Please help me figure 5v mod on this one. It doesn't match any configuration on wiki. Thank you

Does any of these say 1509?
If it does, same thing applies as from the other guides.

You can, or I think you can even leave it there, as long as you connect the 5V to it correctly.

edit: 5V to Pin2... GND might not be needed, but if that doesn't work, do GND as well.
