Thank you for this. Will probably build a few - I have the jailbars issue on my BenQ.

on my system, using BenQ G2420HD (ET-0027-B) October 2009 Rev. 00-132-BA and MITSUBISHI RDT1955 no more jail bars.

How much does it cost (fully assembled)?
I cannot see the prices on PCBWay...

Or do you sell them directly?

Just select “PCB+Assembly” and click “Add to cart”

They cost $1.5 each with a minimum order quantity of 20 - sadly it’s not very convenient to order just one unit assembled.

Wondering if anyone would be interested in doing a bulk by. It would make sense for each region to do this themselves so UK, Italy... unless there is a local provider for such PCB manufacturing at a reasonable price (aiming for cheaper than current adaptors on the market!)

The cost of materials (pricelists from Digikey, RS or Mouser) and PCB standard manufacturing from HK/China are cheap.

I have never spent more than 2,500 yen (~18 EUR) in total to make a single adapter.
Soldering skills are necessary but not advanced to build up the board.

To quote A Field of Dreams "If you build it, they will come". I'd prob be interested but I can't solder for shit... so would need a built one

So, boards come assembled from pcbway and then you have to solder the vga and rgb connectors to the boards, is that correct? thx
