Hi Louie - I just saw your two emails from mid-day on Saturday and responded to them now (Tuesday). As meantioned in the response to your original email that I just sent moments ago, my apologies for the delay in getting back to you as I've hospitalized since Saturday and was just released this afternoon and am now getting back into things.
The lighting difference that you're experiencing is actually a major complaint of customers across the board for the Mayflash and cheap converters do not have their white and black-levels set properly and as such the whites can be very bright and blown out causing a loss of image clarity on particularly bright screens. The HDMI video stream from the ElectronWarp is also set to be full range color which, if the displays are not properly set to handle that color mode can result in an overly dark image. This can also come down to personal preference as well, so there's a subjective element there too.
Considering that I do not typically work on weekends when you're two initial emails were sent and that this review was sent 6.5 hours into the first business day of the week, I'm sorry I was not able to respond quickly enough and that that sealed the deal for you. I'm sorry you have had such a negative experience with my product, I hope you are able to find the product and support that better suits your needs elsewhere.
I'm happy to process a refund for your order according to the refund policy page on my website as soon as I've received a return from the shipping label I sent your way.
