I initially order another item, which I mistakenly thought was right for me… turns out I confused “composite” with “component.” They issued a refund with no hassle; and they led me to the correct (and cheaper) item, which does what I hoped it would do. Seems to be a good company with some really innovative products. Highly recommended.

The seller did everything exactly as they were supposed to. The problem is NOT that the product does not work. The problem is NOT that it doesn’t do what it is designed to do. The product works and does a VERY decent job of converting HDMI to RCA. Here are the problems you will encounter with this device (or that we have encountered with it): First – we had a Sewell VGA to RCA converter and it worked really well but the Dell Zino we were using also had an HDMI output and I thought it might be better to use it instead. That is why we bought this unit. The output is about the same. The difference is when you go from something like 800×600 to 1024×768. This unit begins displaying what I call sparklies. (When the edges of things start getting these alternating lines which makes it look as though the edges have some kind of sparkle to them). The Sewell does a better job of removing those from the image displayed on the TV. The real problem here is – just how do you go about taking something like a 1900×1200 image and reducing it down to a 512×392 resolution image and do it quickly enough so you still even get an image on a TV, still have a halfway decent image, and do it in hardware versus software. This device appears to do this by sacrificing some of the quality of the image produced. My suggestion is to the manufacturer would be to take a look at how PhotoShop does this. PhotoShop is processing still images but a TV just displays still images at a higher rate (like 30 frames per second [30fps]). PhotoShop is a software program and that program runs one heck of a lot slower than a hardware version would run. Thus, whatever algorithm PhotoShop uses is the one that should be used to step the image down from 1900×1200 to 512×392. All I can say is – the device does work but we will be returning to the Sewell device since it also can act as a separate monitor so we can move the screen over to it and still be logged in to the Zino. Also – if anyone from Dell reads this – Dell should try selling the Zino again but this time actually make it HDMI compatible. From what I have read (Tom’s Hardware and other sites) there is a big problem with the Dell Zino in that it can not handle HD properly because Dell used a databus for the graphics which was half of what was needed in order to actually play HD movies. But that is an aside about the Dell Zinos. Otherwise, the Zno was a fantastic system from Dell that they really did not push hard enough to sell. A friend of mine was looking to buy a new computer. I got him to buy one. He went quad core, max memory, best video card you could buy for it. He hasn’t regretted it yet. Been ten years and he is still loving the computer. He even wanted to buy another one but Dell had stopped selling them by then. It really was a super fantastic computer. All they had to do was to fix the video card and it could have taken over the market. Anyway – got off topic there. So to recap: Nice device but you get sparklies at higher resolutions. The Sewell device is better but the one we have is VGA to RCA and not HDMI to RCA.
