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.

This thing is awesome! 8BITJOYSTICK on YouTube did a wonderful video on this device. That’s what gave me the confidence to purchase. It’s 4% of the cost of a Retrotink 4k, but still gives me exactly the visual results I was hoping for. I mostly purchased it for the NEO GEO AES+ when it comes out, in case it doesn’t have a scanline filter, like the Intellivision Sprint didn’t - both made by Plaion. Here are a few screenshots of using my Genesis mini with the Gam3Gear Scanline Generator. Better results than the built in mini’s scanline option IMO. And you can adjust the look with the dials. My tv is an LG C4 OLED. The photos look overly bluish, but I can tell you that in real life, they are perfectly color balanced. Also I want to note that the scanlines are perfectly spaced and even across the entire screen. It looks perfectly consistent and even from the top to the bottom. No banding or stepping. I’m just really impressed by this product. And it’s a much bigger improvement to my retro enjoyment than the mClassic, which I also have.

Had at least one break on me, specifically the scanlines won't generate but most of the other functions worked like the display RGB control. Another thing is it only goes up to 1080p, I do find this (generally) reasonable but the scanline look is so good I wish I could use them on 4K. It helps bridge the gap between CRT and LCD, you can choose them normal or thick. Even modern systems/content it looks great. At the same time scanlines may be preferential so your mileage may vary. At the very least you can turn them off and just tune the screen colors with a knob.

It does exactly what you expect and works fairly well for adding scan lines to game consoles. I use it in conjunction with a video scaler that outputs 480p and my TV reads this scan line generator as 640x480. It's functionally the same resolution, but I think TVs interpret it as a PC resolution which might not work on older TVs, but I've tested it on every TV and computer monitor I have and it works perfect. The color knobs are a nice addition but I've noticed that it can effect how the scan lines look, so I think its better to adjust color directly on your TV. However a major problem with it is that whatever image processing it does produces a very noisy and brightened, somewhat washed out image, which is especially noticeable in large areas that should be black, the output from this makes it dark gray and noisy, including the black borders of the overscan area. The brightening is probably to compensate for how the image darkens overall with the scan lines, but it just doesn't do a good job. Keep in mind that the video quality also depends on your TV when you use this, my 1080p TVs don't scale the 480p signal that well and so it shows a mix of lines that are 2 pixels and 3 pixels tall. 4K TVs will most likely not have that issue, my 1440p computer monitor scales it correctly and it looks fine. The scan lines also darken the image somewhat and some cheaper TVs will wash out the image when you adjust the brightness. Clearly it's certainly not as good as all in one scalers like Retrotink or an OSSC, etc, but I think this is a good enough solution for adding scan lines to game consoles or emulator boxes or whatever else you might have while on a budget.

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.

This thing actually managed to exceed my expectations, though it has a few quirks that will take some getting used to. Applying the scanlines, for instance. You would think that would be handled by the On/Off switch, but really, it's handled by the Vsync switch. The On/Off switch has to be on as well, but you won't see any scanlines without the Vsync option turned on too. No idea why it's like this, but this is an easy thing to live with. The performance of this unit is pretty decent, though you may run into issues depending on your display. I'm using a 32" 4K display, on which I've found that thin scanlines look the best. I've only used this with an Xbox 360, but it works fine. No issues with HDCP or anything like that. No perceptible input lag, either. All in all, a good product. Perhaps a later version could add a bit more customization options for the scanlines, and maybe be a little bit less confusing to use. Besides that? No issues to speak of.

Dead on arrival, no output signal and I figure ok, maybe I’m doing something wrong. I’ve tried an assortment of different micro usb cables and HDMI cables, even different TVs and nothing. Ok, might just be poor luck. I had Amazon issue a replacement and what do you know? The second one is also dead on arrival. This device is low quality and chances of yours working when it arrives are slim. Now I have to waste my time to take both of these to the post office so they can go back to the garbage heap where they belong. Sorry, just being honest. I’m not going to try a third time, this is just ridiculous at this point.

I recently ordered this and it definitely delivers a great scanline filter over your picture without darkening the image like other scanline filters do. The lines can be adjusted odd or even and can also the thickness can be adjusted via a switch. This also has 3 knobs to adjust the Red/Green/Blue hues of the picture but honestly I never use them myself. I use this mainly on my Xbox Series X and play a lot of retro games in Dev Mode and having this hooked up is really nice to have, especially for 16bit/ pixel style games. The only downside is that this will most likely need you to hook a power adapter as it needs external power to turn on otherwise a great thing to have if you enjoy scanlines and want them at a budget price.
