Scan Line Generator Function Switch Description: A：HDMI OUT（HDMI Video-Signal/Audio-Signal Out Interface）. B：HDMI In（HDMI Video-Signal In Interface）. C：EVEN/ODD--->Scan line odd or even number switch . D：WIDTH--->Width switch（Dual or Singular scan lines）. E：ON/OFF---> The total switch of the scan line effect. F：VSYNC--->Image resolution adapter switch（Change the resolution requirement）. G：R G B---> Red Green Blue debugging（Mainly through three potentiometer debugging effect）. Description of vertical signals: 1.If the scan line switch is ON,The scan line has no effect（image darker）,This is vertical signal is out of sync. 2.If you need scan line effect,Toggle (VSYNC) to switch sync, resulting in effect. 3.If you don't need the scan line effect,switch is set to OFF,Image restoration to normal VGA state.（Darken image will restore brightness）. Operation: - ON/OFF-You can easily open or close the scan line, without removing the board. - The intensity of the scanning line can be fine-tuned by three adjustable resistors on the scanner. Packing Includes: 1 x Scanline Generator Review: Also great for older movies! 🍿 - 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. Review: Great quality scanlines, though it could support a few more video modes. - 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. ## Features - Arcade game video image produces the scan line effect，classic，nostalgia，Perfect recall of CRT.15KHZ video image display effect，Re-experience arcade game classic picture，Feel again the wonderful image of the scan line. - Scan Line Generator Function Switch - B：HDMI In（HDMI Video-Signal In Interface）. - A：HDMI OUT（HDMI Video-Signal/Audio-Signal Out Interface） - D：WIDTH--->Width switch（Dual or Singular scan lines） - Note: If you experience screen cutoff or display issues, please try adjusting the output resolution settings on your game console for optimal compatibility and full screen display. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07JYW96Q2 | | AV Output | HDMI | | Antenna Location | Image Capture, Video Recording | | Best Sellers Rank | #425 in Video Converters | | Brand | Gam3Gear | | Built-In Media | Capture Card | | Compatible Devices | Personal Computer | | Customer Reviews | 4.1 4.1 out of 5 stars (165) | | Hardware Interface | HDMI | | Item Weight | 0.08 Kilograms | | Manufacturer | Gam3Gear | | Minimum System Requirements | An HDMI output port | | Model Name | HDMI Scanline Generator | | Model Number | 722267642006 | | Operating System | Windows | | Other Special Features of the Product | HDMI Scanline Generator | | Platform | PlayStation, Windows, Windows 7 | | UPC | 722267642006 | | Video Capture Resolution | 1080p, 4K, 720p | ## Product Details - **Brand:** Gam3Gear - **Hardware Interface:** HDMI - **Operating System:** Windows - **Recommended Uses For Product:** Image Capture, Video Recording - **Video Capture Resolution:** 1080p, 4K, 720p ## Images ![HDMI Scanline Generator Portable Audio Video Output HDMI Image Scan Line Generator Function Board for All Retro Games/Gamers/Mame/Arcade Game/Emulator - Image 1](https://m.media-amazon.com/images/I/61QY3BYtLnL.jpg) ## Questions & Answers **Q: Can this output vertical scan lines instead of horizontal?** A: No **Q: What input resolutions does this unit accept and output?** A: I tested on my 1080p monitor and it worked well. **Q: what is this used for?** A: this is used to create scanlines on a TV/Monitor with hdmi in puts. just like the old CRT TVs of the 90s and earlier. its primarily used for retro gaming. I used it for a retropie build and it worked amazingly. since the pi isnt a power house it was easier to use this instead of a filter that take processing power away from the pi. **Q: Can you adjust the thickness of the lines or is it only a toggle between two settings?** A: Sadly you can't fully customize them I wish you could you could only choose from about two types of thicknesses and then you can also invert which lines are shaded in ## Customer Reviews ### ⭐⭐⭐⭐⭐ Also great for older movies! 🍿 *by J***8 on August 19, 2024* 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.

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. ## Frequently Bought Together - Gam3Gear HDMI Scanline Generator Portable Audio Video Output HDMI Image Scan Line Generator Function Board for All Retro Games/Gamers/Mame/Arcade Game/Emulator - ABLEWE RCA to HDMI,AV to HDMI Converter, 1080P Mini RCA Composite CVBS Video Audio Converter Adapter Supporting PAL/NTSC for TV/PC/ PS3/ STB/Xbox VHS/VCR/Blue-Ray DVD Players - Marseille mClassic Pixel Enhancer & upscaler for Nintendo Switch and Retro Consoles Including Xbox, PlayStation, Gamecube, N64, Wii, SNES, Genesis, Dreamcast, and More --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/95708432-hdmi-scanline-generator-portable-audio-video-output-hdmi-image-scan](https://www.desertcart.tn/products/95708432-hdmi-scanline-generator-portable-audio-video-output-hdmi-image-scan) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-06*
