RF to HDMI Converter Adapter All-Standard Converter Analog TV Receiver Adapter with Remote Control for Projectors, Multimedia Teaching, Network Engineering(US)

awesome little device. the hardest part to get it to work was changing the language from chinese to english. the 2nd hardest part was changing the sound format to one that worked with my 10+ year old best buy insignia tv. 3rd hardest part wasn't hard because i read someone else's review that said you needed to make sure you had a pal to coax adapter. which i had already bought and found out the device came with one. i also already had the rf to coax adapter to plug into the atari 2600 and that into the pal adapter. speaking of pal, change the video setting on the device to ntsc instead of pal, and recommending 4x3 resolution instead of 16x9 for more of the classic look. two thumbs up. worked right the first time on an original 1982 atari 2600.

Works as advertised. Instructions are rudimentary. Getting into English is the first step. Aspect ratio, PAL vs. NTSC, and sound need to be set. Channel scan takes a while. But it is the cheapest demodulator I could find. I used it on a Colecovision.

I was unable to get this decoder to work, despite having 50 years professional experience with computers, electronics, etc. First of all, the "COAX" connection isn't standard US coax but looks like PAL. I asked the vendor what to use. After a day and a half, the reply was "type C to BNC." Huh? Type C is for USB and there are no BNC lugs on the input port. I asked again if they meant type F (which is standard screw-on coax), but never got a reply. The "coax" connection doesn't have BNC lugs on it, so I wasted some more time getting COAX to PAL adapters. Nowhere in the listing or Amazon recommendations is a special adapter mentioned. Another me-too Chinese product (same picture, functions, etc.) had a recommendation for PAL adapters, so I went with that. Next I had to figure out where to go to change the On Screen Display (OSD) from Chinese to English and set up other functions. The calendar has display issues, the dates don't show up well on the TV screen. I could never get any channels acquired, either with the "Auto Search" or manual functions despite several attempts. Having spent hours messing with this decoder, I just gave up and bought a different brand decoder, ZJBox, on Amazon for about $10 more. It HAS F-COAX connectors already built in. The menu on it starts up in English (OMG!), with the country as USA (double OMG). Next, auto search for channels. The ZJBox took a few minutes to scan (the same COAX connection, no issues there) and came up with 47 different channels, on all of which I could get a good picture. All that took a couple of minutes and couldn't have been simpler. So, if you want to get a decoder which works right out of the box, I recommend ZJBox (Asin B07Z5RGLK6). The SAIZHUO (is this some play on words for "Says Who?") isn't even heavy enough to use as a paper weight, so I returned it.

It is working, but I get a lot of noise in the picture no matter how I have it set.

I read the reviews so I was a little nervous about buying this, but it looked exactly what I needed, and it was! I needed a decoder that could accept as input a UK coac cable from a 1980's home computer (a zx spectrum) and convert it to HDMI so I could bring the ancient computer up on my monitor. Once I had figured out how to change the OSD to english from chinese and read the minute instructions, I tuned it in. The picture is not flawless, but I need to get a better cable from the computer, it is thin and over 40 years old, a bit like me if thin meant fat and 40 meant almost 60. Overall, a great little gadget which means I won't need to modify my vintage computers (thats right, I have several).

You will also need to purchase an F female to PAL male adapter, to make this work with an Intellivision in the US.

35 year video and broadcast professional here with equally long tinkerer's experience. Unit powers on. I can see menues and output descriptions change as I use the remote. Swapped all the things: cables, TVs, input sources. Input (Colecovision) works fine using VHS deck as an RF converter - only the dedicated RF to HDMI converter fails. Issue is an obvious sync incompatibility. No desire to crack the case and test voltage/hrz. Unit brand new but bad out of the box. Returning.

YouTubeで設定のやり方を出している方がいたのでそれを見ながらファミコンに無事接続出来ました。

日本のファミコンを液晶テレビに映す用に購入しました。 その場合そのままだとアンテナの端子を接続できないので変換コネクターもセットで買ってください。ご一緒にどうですか？みたいな画面に映っているやつで構わないです。 説明書が英語と中国語しかなくてわかりにくかったです。 翻訳して理解しました。 細かく設定するとブラウン管に映す時に近い画質でファミコンを映すことができました。多分PCエンジンとかも同じやり方で映ると思います。 ありがとうございます。
