4K Gamer Pro Review: Sharp-Scale 1080p to 4K

The 4K Gamer Pro is a device that sharp-scales 1080p to 4K, using their custom scaling technique (not nearest-neighbor).  It’s basically the opposite of an mCable, as it’s sharp-scaling instead of soft-scaling…but unlike the mCable / mClassic, this outputs 4K60.  Check out the video for a full analysis and some screenshots below!

EDIT:  People in the comments and on social media keep insisting this is the exact same as turning your TV’s sharpness all the way up.  It’s absolutely not.  I’m not trying to say this thing’s perfect (I’d also really like a basic NN mode), but it’s absolutely performing a sharper scale than almost any TV would, which is great for 2D graphics.

I spent a week testing this device and confirmed its “safe” to use:  There’s no lag, it doesn’t compress colors and there are no frame drops.  While it’s not a retro-standard “nearest-neighbor” scale, it does truly scale the image to 4K60 and the scaling algorithm they use is sharp enough to make 2D graphics games of all era’s shine!  For 3D graphics, that will be up to you to decide:  I don’t think this is the right choice for early 3D graphics (they don’t market it towards those anyway), but I did see a few scenarios where I liked the effect in modern games.  Basically, if you have a 1080p source you’d like to see sharp-scaled, this device is worth considering!

Here’s some screenshots pulled from the video.  These were actually pulled from 4K60 videos of my TV (as explained in the video), so any motion blur you see is the cheap TV and not the devices in the comparison (click on each for a full-sized image):

MiSTer Users:  You may need to set a custom modeline for this device to be compatible.  Update your MiSTer via your favorite script, then after it’s complete edit the “video_mode” line in the MiSTer.ini file to this:


This should work fine, however some people have reported issues with the analog output when this mode is set.  If that’s the case, you can assign an alternate .ini file that you can activate any time the 4K Gamer Pro is in use.
