Kaico Sega Dreamcast HDMI Adapter – Plug & Play HDMI Converter for Sega Dreamcast Console – Supports DC VGA & RGBS Output – All-in-One AV Cable for All Dreamcast Games

I read various reviews about this "not working" and was concerned but thought I'd try it anyway.Plugged it in and... NOTHING!!!!... Now considering I had to pull my entertainment center aware from the wall and get behind to cable things up... I was a little miffed at this point... But then... I have HDMI cables going into a HDMI switch etc so I thought I'd start with the basics... straight into the TV. Still nothing....The documentation makes no mention that there is a small hole in the case on the underside and I wondered what did that do... unplugged everything to get a better look but no idea... plugged it back in FIRMLY into the Dreamcast and bingo, the little hole was actually a BLUE LED and it lit up!!!! Checked the TV, Yup... I have a signal. Plugged everything back into the various switches and it was still all working great.Put everything back in place (moving my entertainment center back against the wall with its array of cables etc) and grabbed a handful of Sega games. The video quality difference between composite (The old yellow video cable and red-white sound) and the VGA to HDMI is very noticeable. That's hardly surprising as Dreamcast VGA is 480 lines (Comparable to DVD) and the composite in the Dreamcast is said to only be about 240 lines. I had previously used the composite (on a 4K TV) using a HDMI converter and to be honest I thought it was acceptable. However after trying the VGA-HDMI converter, the difference is night and day better.There is one unfortunate downfall.... As I discovered in my haste and enthusiasm to try games.... not all Sega games support VGA... You can't blame the VGA-HDMI converter for this but it is rather irritating. However, the volume of games I've tried thus far that fail are currently 1 failure out of 12 tested.... When you try to load the game it tells you it's not compatible with the display cable... It's a game I'm not bothered about so no biggee.I no longer have the old Dreamcast to VGA adapter as that bit the bullet years ago and I've not tried any other adapter to be able to compare against this one. I will say for $30 it was my upper limit of what I would pay for the feature and although there were others for $20, I liked the reviews on this one more.So for all the folks who had "bad" ones I wonder if you suffered the same issue I did when I first tried it... Not saying there couldn't be a bad one now and then. For all said, I'd highly recommend this unit. Just be aware the documentation is brief to say the least... and once the cable is plugged in, check the Blue LED lights on the underside of the unit. No LED, no workee... make sure the Dreamcast is powered up and try firmly reinserting the cable into the Dreamcast.UPDATESo after playing some of the VGA games, which I am really impressed with the quality, I switched back to the Composite to play a couple of games that I've subsequently found required that. Couple of them I do enjoy playing. Considering I had been using the composite for a long time before buying this adapter and I thought I was previously okay with the quality, I was stunned at the obvious drop in quality going back. Even the opening power on screen shows a clear loss in image quality. So being finicky, I've now set mine up so that by default I will play in VGA mode but with just a simple cable change in the back of the Sega Dreamcast I can revert to just the composite video for those games I really want to continue to play. You do have to power cycle the Dreamcast if you want to change back and forth. Just changing the cables doesn't work but that's no biggee.Still ecstatic at the improved quality using this adapter. Well worth the money. BTW, Played "Crazy Taxi" and "Silent Scope" both in VGA mode... damn even after all these years, the Dreamcast really does shine. I totally accept new consoles have HD graphics etc but it's the simplicity of the games not just the graphics that make them fun to play. Kudos on this adapter.

For the price, the image quality is incredible on modern TV’s! VGA output on the Dreamcast has certainly aged well, and this is a convenient way to see the best visuals the console has to offer! The16x9 format is slightly off-center on my display, but it is barely noticeable in gameplay as it does still fit the screen.Of course, do be mindful of what your voltages are, as the device uses electricity from the console.My only criticism is that the plug sticks out of the end of the Dreamcast, which makes me concerned of it bending and breaking.

This product works really well even though the package said 720p it goes up to 1080p

This thing is amazing. I'm now able to stream myself playing Dreamcast games on Twitch using this device. I love that it has a switch to go from Composite to VGA mode. This makes it where you can play any game in the library at the flip of a switch. I mainly play 2D and 3D fighters on my Dreamcast, and this has made it where I can do it on my modern computer monitors. I'm very happy with the device and highly recommend it to anyone who has a Dreamcast they want to play on a modern screen.For my money, this is the best DC HDMI adapter you could buy and it's sold at a great price. I'd give it 100 stars if I could!!!

Played both Sonic Adventure 2 and SoulCalibur, both looked great on my PAL Dreamcast. It didn't produce perfect picture, but the trade was definitely worth it. Great product, highly recommended.

Good quality, sharp, no lag

I knew this was a clone product of an open-source project, but man, they're so cheaply produced. Sometimes it works, sometimes it doesn't. Completely random if it will crash before 30 minutes have passed, but guaranteed to crash after 30 minutes or so.As a bonus, it leaves a slight 'plasticy' smell as it gets warm. I'm almost certain this product is defective; however, I can't verify this. I would contact support and ask for a new one, but I'm more than certain it'll be the same quality.

I'll start by saying for 40 bucks, this is an alright product for a quick fix. I recently lost my composite cords, so I thought that I'd bite the bullet and purchase this device.But man, the entire image is just... washed out. I tried Soul Calibur and Sonic Adventure and immediately noticed how bright the display was. Especially in comparison to reviews on YouTube. It's not a deal breaker, but for an extra 40 bucks you can get a much more quality device like the Beharbros Akura.
