Best video fuser for DMA: how fusers work and which one to buy

A video fuser puts both of your computers on one monitor. Your game comes from your main PC, your software's overlay comes from your second computer, and the fuser lays one over the other. Nothing gets installed on either PC. The best one for you is the one that matches your monitor's input, resolution and refresh rate.

What a fuser does in a DMA setup

Your DMA card sends your main PC's memory to your second computer, and your software draws what it finds, like boxes around players. That drawing is on the second computer's screen. A fuser brings it over to the monitor you play on.

• Two pictures go in.
  One from your main PC and one from your second computer, the same way each would go to a monitor.
• Black turns see-through.
  Anything black on the second computer's picture lets the game show through. Most software draws its overlay on black, so only the overlay sits on top of your game.
• One picture comes out.
  The fuser sends the merged picture to your monitor.
• It only handles the picture.
  It doesn't carry your keyboard or mouse. You still need a way to control the second computer, like a second keyboard and mouse or a KVM switch.

Do you need one?

No. A fuser is the tidy option, but a second monitor or a KVM switch works too. With a second monitor you look away from your game to see the overlay. With a KVM switch you flip between the two computers. A fuser shows both at once. Do I need a video fuser? compares them, capture cards included.

What to look for in a video fuser

• Your monitor's input.
  HDMI or DisplayPort. The fuser's output has to match a free input on your monitor.
• Your resolution and refresh rate.
  Check the fuser supports the exact mode you play at, like 1440p at 165Hz. A fuser that can't do your mode drops you to a lower one.
• Your second computer's output.
  It has to send the same mode. Some fusers also need a certain graphics card on the second computer. Which second PC works with each fuser.
• Picture quality.
  Full 4:4:4 color means the picture isn't squeezed to save bandwidth, so text and thin lines stay sharp.
• Latency.
  Look for a fuser that states zero latency, so the game isn't delayed on its way to your monitor.
• Controls.
  A remote is handy, and buttons on the unit help if you lose it.
• Genuine hardware.
  Some fusers get faked, mostly on the second-hand market, and a fake one can make your overlay wobble. Fake fusers and clone DMA cards.

How our fusers compare

We sell three GODLIKE fusers. All three are plug and play, have zero latency and come with a remote.

Which one to buy

• HDMI monitor, 1440p at 144Hz or less.
  The 10th Gen HDMI.
• DisplayPort monitor, or 1440p at 165Hz.
  The 10th Gen DP. Its inputs are still HDMI.
• 1440p at 240Hz, 4K at 120Hz, or 1080p above 240Hz.
  Only the 4K Pro does those. Check your second computer's graphics first, because most office mini PCs can't drive it.
• 3440 x 1440 ultrawide.
  The 10th Gen HDMI. It does 100Hz at that size, and the 4K Pro only does 60Hz.

There are no returns on hardware, so check your monitor and your second computer before you buy. What is a DMA video fuser? goes deeper on the three models and the cables each one needs.

Setup basics

1. Main PC into PC1.
   Use the cable your main PC already uses for your monitor.
2. Second computer into PC2.
   The cables in the box cover the inputs.
3. Fuser output into your monitor.
   Use the power adapter from the fuser's own box.
4. Set the second computer's background to plain black.
   Anything else covers your game.
5. Set both computers to the same resolution and refresh rate.
   Then pick the mode and turn fusion on with the remote.

How to set up a GODLIKE video fuser walks you through every step, with fixes for no picture, a black screen when a game starts, and being stuck at 60Hz.

Common questions

• Does a fuser add input lag?
  GODLIKE states zero latency on all three. The fuser only merges pictures, so your mouse and keyboard don't go through it.
• Does it need drivers or software?
  No. It's plug and play, and nothing gets installed on either computer.
• Does sound go through it?
  GODLIKE doesn't say, and none of the three has its own audio jack. Do I need a video fuser? covers your options for sound.
• Can I record or stream with the overlay showing?
  Yes. Record or stream with your DMA overlay shows how.
• Can my second computer be a laptop or mini PC?
  For the 10th Gen models, usually, if it has an HDMI output that can send your mode. The 4K Pro needs real graphics. Which second PC works with each fuser.
• What if it arrives faulty?
  It has a 3-month warranty and is replaced if it's faulty. Open a ticket in our Discord.
