HDMI Scanline Generator Portable Audio Video Output HDMI Image Scan Line Generator Function Board for All Retro Games/Gamers/Mame/Arcade Game/Emulator

So first of all it’s a super easy setup but it doesn’t come with a micro usb cable which you may need depending on the length of your cabling. Just assume you’ll need one. It can be finicky with the sizing of the scan lines because those are changed based on the input resolution you use with it. In my experience it’s best to send 1080p so you can get the finest scan lines that aren’t hefty and distracting. What’s shown in my samples are 1080p and the 2nd finest ones available. The finest ones aren’t noticeable at 1080p but can be seen in 720p and lower because they get thicker. There’s 4 scan line choices from finest to thickest. But I wish they were easier to change. There’s a tiny button next to the output HDMI and it switches from the finest to thicker lines and then the side switch swaps between two sizes in the category the button is on. Not a dealbreaker but something to note. If you use this for movies then you’ll find your preference and likely leave it there anyways. The on and off switch can also be finicky where when you turn it off, the image remains dark without scan lines. Going on and off it may take a few tries and it’ll fix itself that way. You’ll want to leave it on unless it’s not in use. As you can see I was able to capture footage direct. It does remove hdcp. My capture follows the rules and I went direct from a fire stick into the scan line generator into my capture and it worked to my surprise. I want to use it for the free streaming services that have old movies so I can watch with scan lines. I tested with a PS3 and a DVD of Ronin Warriors and all worked great. Screenshots from the clips I made without editing. As for gaming it works great. No latency issues that I could detect and I play Crazy Taxi somewhat competitively and didn’t feel any added lag whatsoever. For $36 it has so many uses and is compatible with many devices although it’s no guarantee it will work with all HDMI games or players. I do have a Sony blue-ray it wouldn’t work with so keep that in mind. I wish it was cheaper but now that I’ve had so much success with various devices I see the value there. It’s worth it just for movies and is a cheap scan line option for gamers. For best results, send it 1080p. I almost forgot that there’s RGB Potentiometers to dial in each of those colors. The brighter they are the less apparent the scan lines become. It’s a nice feature to have because some cheap gaming adapters don’t display colors accurately and this can at least help fix that to some extent. Anyways, long review I hope I covered it all. Can’t speak on longevity yet but I power it off when not in use. It’s bringing new life to older movies I’ve been reluctant to watch because they don’t look right on modern displays.

First of all, when it's working it works great. I use it with my consolized Neo Geo MVS with an HDMI cable and a CoreGrafx through an SSDS3 and RetroTink 2X. In both cases the scanlines look amazing, though it doesn't support all modes of the RetroTink 2X. This is the final piece of the puzzle for those systems on modern displays. I have an OSSC, but honestly I think the scanlines through this device look better. I've attached screenshots from both systems running through this device. Although it has a micro USB port, it seems to be optional. I have it working on both systems without using USB power. However, it doesn't accept all video signals and when it's not working it may appear to be completely non-functional aside from the LED. One of the modes on my RetroTink 2X (passthrough, I believe) doesn't work with it for example. The on/off switch does not control the LED, but that's because it controls the scanline function and not device power. A bit counter-intuitive, but at least you know that the device is on. Overall I give it 4 stars, if they make it work with more video modes I'd give it 5. The output looks great when it's working.

At first I saw this and thought, oh, my emulators already do that. This is better. WAY better. Is it as good as a real CRT? Of course not! No flat-screen will ever look as be as a real CRT, and it's about more than just scan lines. Real CRTs had brighter whites and darker blacks and all kinds of colors modern-day glass screens just can't do. Obviously, the real thing is always best. But with that question out of the way, I will say this: it's the next best thing. I say that because it's not just for gaming. In fact, it's for your whole TV or computer. In fact, I think I'll be turning all off those CRT setting on my emulators, because I'll be using this instead. And then when I'm done playing, my computer will still have that familiar look, no matter what I do. And as someone else said, it's great for old movies! I think when my old CRT finally bites the dust, this will be what ends up replacing it. It's that good. Now, that's not to say it's perfect. I was a bit taken aback when I saw it was in the same kind of static-resistant bags they use for circuit boards. But don't worry - it's not like that. Unless you're constantly revisiting this product listing, the settings are all a matter of trial and error, because there are no instructions. And of course, it's one more thing to plug in (though I knew that when I bought it, just a heads-up). But I mean shoot, this thing is really cool for the price. When I hook it up, it really does look like a CRT. Almost. Like I said, as close as present-day tech can get. It looks awesome on games and movies, and even on my computer. I use Linux (and I love that it's compatible with Linux) and my desktop has a Windows 95 theme. With this thing, it reminds me that much more of my first computer - and that's saying something. I also like the RGB settings and stuff; some emulators don't even do that! So yeah, no product is perfect, but IMO this is a good one.
