PhotoFast 4K Gamer Pro Video Game Console HDMI 4K upscaler 1080p to 4k @60fps without lag upscale for Nintendo Switch/Nintendo Switch OLED/Wii U/PlayStation 4 / PS3 / Xbox & more

TLDR: Actually Upscale to 4K but takes a 1080p Input. For TVs it can be used alone. For 4K Monitors you'll need to invest extra money into the Marseille MCable Gaming Edition or else it'll look jagged on your 4K Computer Monitor. Third setting is a bit much, 2nd setting seems to be the happy point. Final Connection is Switch HDMI OUT mCable Gaming Edition > HDMI Coupler (Female to Female) > PhotoFast 4K Scaler > 4k Computer MonitorI recently switch from 1440p to 4k Monitor three months ago. I got the Samsung Neo G7, and had been using the mClassic with my switch. The mClassic only upscale to 1440p. It still looked great but I wanted 4k and after doing some searching I landed on this upscale and a couple of video review about it. Decided to go for it after seeing the first 2 detail reviews about it.Upon receiving the 4K Upscaler, I hook it up to my Switch, turn on the monitor, and......meh. It didn't look bad but definitely not smooth around edges of objects and people. But I did expect this as the review I'd looked at state that this Upscaler Sharpen. The review before mine mention adding the mClassic in line with the 4K Upscaler as the mClassic Smooth jagged edges (Anti-Aliasing).... but that didn't work for a my Samsung Neo G7 (4K Computer Monitor) as the mClassic Max Resolution is 1440p and the 4K Upscaler ONLY accepts 1080p input. So something would override the 4K scaler and I would only get 1440p Resolution when daisy chaining them together.Lucky, I had a mCable Gaming Edition (Same company that focus on Anti-Aliasing just the cable vs an small adapter). The cable does not upscale to 1440p, so the daisy chain was mCable Gaming Edition > HDMI Coupler (Female to Female) > PhotoFast 4K Scaler > 4k Computer Monitor. Started up Splatoon 3 and....WOW exactly what I was hoping for 4K Scaling, Smooth, no lag, no loss in colors, and no more jagged edges.Now I'll say that's ALOT of investment just to get 4K Scaling if you using a computer monitors as your going to need to buy the mCable ($110 when on sale) and a HDMI Coupler ($7-10). If you playing on a TV depending on how it look you may need to buy the mClassic ($99) if it looks to jagged to you. But look at the other reviews for that decision.I've only tested this for roughly 12 hours straight, so I will update in the future (if I remember) on how far it last and how other games look.

It does what I wanted it to do. I knew that using this alone would upscale and sharpen low-resolution games, but also severely pronounce jagged edges. Thats why this should be paired with the mClassic, which first anti-aliases the image. It certainly improves upon the image sent out by the mClassic, making things look sharper and of higher resolution. Although I thought that I wouldn't, I definitely did notice sharpening artifacts in the medium and high settings, so I will be using it in the low setting, which still looks great. This is not a substitute for native 4K, and even when paired with the mClassic, the low-resolution base image shines through at times. That being said, it’s a definite improvement and loosely resembles a native 4K presentation (when combined), is better than using just the mClassic alone, and I am satisfied with the result.

was excited to try this along with my mCable gaming edition HDMI cable, as i've read the reviews on here stating how great it is. However, when I plug this into the female to female hdmi coupler on my mCable and turn it on, there is no image or signal any longer. different hdmi cord on the tv end of thing, still no signal when you turn the 4k gamer pro on. Decided maybe it was the mCable chain. Wrong again, as plugging this directly into the switch dock resulted in the same loss of signal when the 4k gamer pro is turned on. Turn it off and the signal bypass right on through. My switch settings are to 1080p for TV. Just stick to an mCable or mClassic as this is almost twice the price and doesn't even do a damn thing.

Upon learning that this video image upscaler existed, I looked at some other reviews online to determine whether or not it was legitimate enough to buy. I was somewhat eager to receive and test this out after deciding I would initially make the purchase. After two weeks of usage specifically for the Nintendo Switch, I can say that this product does everything it advertises, that is, upscales images to a 4K resolution and increases color contrast, most importantly successfully processing the source without lag/delay. The difference in image quality with vs. without this is subtle, but noticeable both under scrutiny and casual, sustained play. I've compared games like Splatoon 3 and Mario Kart 8 Deluxe, but I think there's even further benefits to be had using this with games that run natively sup-1080p, like Xenoblade Chronicles 3 and Persona 5 Royal. Seeing a sharper, clearer image on games on Switch with denser colors is remarkable, but that's essentially all you're paying for. It's up to your discretion if that relevant, albeit minor effect is worth the price that makes it possible. A proper upgraded Switch model could potentially entirely mitigate this product's purpose, unless you have older consoles as well, especially if games get further optimized for the better hardware (i.e. frame rates, lighting, texture quality, other graphical elements beyond simple image upscaling). This is an acquired luxury that's certainly nice to have, but it comes with a hefty price tag. I can only recommend it if you think that justifies what this offers.
