Video fusers for DMA: how they work, which to buy
How it works
Both computers send out a normal picture, the same way they would to a monitor. The fuser lays the second computer's picture over the main PC's and sends one merged picture to your monitor. Nothing is installed on either computer. Anything black on the second computer's picture is see-through, so set its desktop background to black. Most software draws its overlay on black, so only the overlay shows over your game.
On the two 10th Gen models, GODLIKE states full 4:4:4 color with no compression (the picture isn't squeezed to save bandwidth), EDID pass-through (each graphics card sees your real monitor and offers its normal modes), and switching between the two computers with no black screen or stutter. The 4K Pro's listing doesn't state any of these either way. All three have zero latency.
A fuser is optional. A second monitor or a KVM switch works too, and Do I need a video fuser? compares them.
The three we sell
| 10th Gen HDMI | 10th Gen DP | 4K Pro | |
|---|---|---|---|
| Inputs (from your two computers) | 2 HDMI | 2 HDMI | 2 DisplayPort |
| Output (to your monitor) | 1 HDMI | HDMI and DisplayPort, both usable at once | 1 DisplayPort |
| Top modes | 1080p 240Hz, 1440p 144Hz, 3440 × 1440 100Hz, 4K 60Hz | 1080p 240Hz, 1440p 165Hz, 3K 100Hz, 4K 60Hz | 1080p 360Hz, 1440p 240Hz, 4K 120Hz, 3440 × 1440 60Hz |
| Power | 12V 2A adapter from its box | 12V adapter from its box | 12V 2A adapter from its box, US plug, with an EU plug adapter |
| Cables in the box | 2 HDMI | 2 HDMI | 2 DisplayPort |
| Controls | Remote only | Remote and buttons on the unit | Remote, front buttons and status lights |
| Second computer needs | An HDMI output that can send your mode | An HDMI output that can send your mode | A DisplayPort output and at least an AMD RX 470, an NVIDIA RTX 2060 or Radeon 780M graphics |
Every model runs on the adapter from its own box, so don't swap in a spare from another device.
Every 10th Gen unit runs its own firmware, not one shared by every box. The 4K Pro has a premium RGB design.
Which one
Start from your monitor: which input is free, and what resolution and refresh rate you actually play at. Your second computer has to be able to send that same mode, and Which second PC works with which fuser checks its ports, adapters included.
- HDMI monitor, 1440p at 144Hz or less.
The HDMI model. - DisplayPort monitor, 1440p at 165Hz, or you want both outputs.
The DP model. Its inputs are still HDMI, like the HDMI model's. - 1440p at 240Hz, 4K at 120Hz, or 1080p above 240Hz.
Only the 4K Pro reaches those. Your second computer needs the graphics in the table and a DisplayPort output, which rules out most office mini PCs and N100 boxes. Check this before you buy, because there are no returns on hardware. - 3440 × 1440 ultrawide.
The HDMI model. It does 100Hz at that size and the 4K Pro only does 60Hz, so the expensive one is actually worse for you.
Cables
- Count the connections.
Two inputs and one output is three cables, or four if you use both outputs on the DP model. Two come in the box, so plan on at least one more, of the type your monitor takes. On the DP model with a DisplayPort monitor, that one is a DisplayPort cable. - Rate them for your mode.
An 18 Gbps (Premium High Speed) HDMI cable covers every mode on the HDMI model. For 1440p at 165Hz on the DP model, use 48 Gbps Ultra High Speed HDMI cables on the inputs. For the 4K Pro's top modes, a VESA-certified DP8K cable is the safe choice. - Avoid adapters if you can.
