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.

Product worked for the most part. You mess with the RGB and the darker you go the better you can see the lines. My only problem was the screen gets cut off on the left side. I ordered a replacement and we will see if it fixes the issue. The one picture you can see it cut off. The other picture you can see how it should be.Update: I got my replacement. I had the same issue and after some troubleshooting got it fixed. Some TVs you have to disable the overcan I think it is called, others you change the input type to direct (Roku TV). My older smart Samsung 6 series I had to change the input to PC. Now it works as it should. I deduct one star for that because it should not take a long time to have to figure out a work around and fix. It still slightly cuts off the picture but it is manageable. However, now that it is working I am happy with the product. The majoras mask pictures show two different thicknesses of the lines. This is on a 40 inch samsung UHD TV going from a retroscaler 2x to this scaline generator using SVideo cables for N64.

Does exactly what you want it to do. The RGB knobs really add a nice touch to being able to adjust color levels. For the price, I would say you can't beat it.

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.

This summer, I went on a quest to move all my retro systems to HDMI. This meant buying HDMI converter cables for Sega Saturn (Xtreme Cables), PS2 (XAgent), and N64 (Hyperkin). I was very happy with these cables as is, except for the Hyperkin, because it relies on an S-video signal instead of RGB like the others...this is a limitation of the N64, though, since that system doesn't offer RGB output without internal modifications/additional chips. But, as a lover of the N64, I couldn't help but be disappointed by the picture quality via the Hyperkin HDMI cable.Adding this scanline generator absolutely saves the N64 with Hyperkin HDMI cable. The picture goes from a smeared mess to looking like a very sharp, well-tuned CRT. I am loving the picture I get with this device. It does cause the source volume to drop, however, so you have to crank the volume a bit.There are a multitude of switches, buttons, and dials on this...they all generally achieve differing degrees of scanline action: off, on, thick, thin, and intensity per color channel. The dials in the middle allow you to adjust colors on the fly and either intensify or weaken the scanline effect. Overall, I ended up going with narrow scanlines at maximum intensity.Screenshots taken with my phone really don't capture the effect this device has on the overall picture, but it is pretty great. Games look like they should, as everything prior to the HDMI systems (PS3/Xbox 360) was designed with a CRT in mind. I've attached a few, but as other reviews have mentioned, you have to see it in person. See the shots of "Press Start" for scanlines on vs off...again, it's hard to see on cellphone photos but in person it looks totally right.I haven't had sound quality issues, but will update if I do.Do expect more cabling mess using this...well worth it though!
