Do I need a fuser for a two-PC setup?

Only if you want both PCs on one monitor. Without a fuser you need a second screen.

Does a fuser add latency?

Hardware fusers pass the main PC's picture straight through; models like the GodLike Fusion 4K Pro are built for lossless, real-time output.

Which fuser is best for 1080p 360 Hz?

The DC 4K120 Fuser or the GodLike Fusion 4K Pro; for more than 360 Hz, the DC505 or DC1A686.

How to choose a fuser

A fuser merges the picture of two PCs onto one monitor. The right one depends on one thing above all: your monitor's resolution and refresh rate. A fuser that can't keep up limits your main PC's picture, so pick one that matches or beats your monitor.

Step 1 — check your monitor

Find your monitor's native resolution (1080p, 1440p or 4K) and maximum refresh rate (for example 240 Hz).
Check which cable you use: HDMI or DisplayPort.

Step 2 — compare the models

Fuser	4K	1440p	1080p	Ports
DC Fuser	60 Hz	144 Hz	240 Hz	HDMI + DP
GODLIKE Fuser	60 Hz	165 Hz	240 Hz	HDMI + DP
DC 4K120 Fuser	120 Hz	240 Hz	360 Hz	HDMI 2.1 + DP
GodLike Fusion 4K Pro	120 Hz	240 Hz	360 Hz	DP
DC505 4K Fuser	158 Hz	355 Hz	540 Hz	—
DC1A686 DP 1.4	164 Hz	364 Hz	639 Hz	DP only

The DC1A686 also runs 3440 × 1440 ultrawide at 264 Hz and 720p at 1000 Hz.

Step 3 — match it

1080p up to 240 Hz: DC Fuser or GODLIKE Fuser.
1440p 240 Hz or 1080p 360 Hz: DC 4K120 or GodLike Fusion 4K Pro.
Very high refresh rates: DC505 (1080p 540 Hz) or DC1A686 (1080p 639 Hz, DisplayPort only).

Good to know

The GodLike Fusion 4K Pro needs a second-PC GPU of at least an RX 470, RTX 2060 or Radeon 780M.
The DC1A686 needs DisplayPort on both your PC and your monitor.
