2D HMD with cinema2go – first impressions

in december 2020, cinema2go offered 60% discount, so i gave it a chance and ordered

the product reached first the german lokal ZOLL export department, to pay taxes.

First test of the MOGO HDMI.. it is very low/light weight..
plugged in the HDMI and the USB cables…
I started my PC Win10, and see that the MOGO uses a topfoison display

The HDMI and USB cavles are,
with estimated 1m, not long enough for my „gaming“ rig.
Using windows display settings and not the geforce,
set 2 display to 1440×2560 60Hz and set horizontal,
then the MOGO screen show correct view.

First impressions:
When screens is black, it seems that there are some pixels malfunction.
The lenses cause distortions.. barrel and cromatic..
i will not use this in that form.

and the screen is only sharp when the picture stands still,
in other case.. it will blur a bit… i dont know if that effect caused by display technic or by the windows driver, or even comes with 60Hz.


My conclusion:
So i decided to rip the MOGO in parts,
to use, to test CARSON +4dioptrin plugable glasses.

and the result was much more worth.

So for that new project, i need to create new parts in autodesk fusion360 to print needed parts in 3d, using the 3D printers in our local fab-lab/makerspace.

MOGO uses a low distance eye-to-display, that is the reason that special lenses are needed, which will end up with distortions and other drawbacks.
With my changed setup i will have to use a greater distance distance eye-to-display, thats seems possible to me, because the display is so low/leight weight, so that a lever, caused by greater distance should not have great effect.
A greater distance eye-to-display is better for the comfortable view to the display corners!

now i have following parts:
– Display with connectors(HDMI+USBmini) and with foldable left and right „arms“.
– lense holder with a nose part
– face mask with strechable rubber bands for head

TODO:
– create a holder for Carson lenses, that can connect/plugged to the facemask, as like as the orig lense holder before,
lense position:
depth: the lense has to sit closest to the eyes/face with slight or now touch.. but not more than 10mm away…
vertical: adjustable
horizontal: fixed
– stiffen the foldable arms
– create extensions of the arms
– connector between arms and face mask
