Fuser buying guide for DMA setups — how to choose the right one for your monitor
The fuser is a core part of a DMA setup — it merges the display signal between your two PCs and carries the picture at high resolution and refresh rate with no delay. Picking the wrong fuser means either paying more than you need, or getting a lower refresh rate than your monitor can handle. In this guide we explain what a fuser is, how to choose the right one for you, and compare the options at DMA Saudi with their real prices.
What is a fuser?
In a dual-PC DMA setup you have two PCs, and the fuser is the device that merges the display signal between them and outputs it to a single monitor. A good fuser passes the picture through at the highest resolution and refresh rate your monitor supports, with no loss in quality and no added latency.
The most important factor when choosing a fuser is the supported refresh rate at each resolution: how many Hz it gives you at 1080p, 2K and 4K. The higher the supported refresh rate, the smoother the picture in competitive games.

The budget fuser — Fuser Dichen 2K
If your monitor is 2K and your budget is limited, theFuser Dichen 2K is an excellent entry point at SAR 899. It gives you stable performance at 2K without paying for 4K refresh rates you may not need.
The balanced choice — DC 4K120 and Godlike 4K Pro
If your monitor is 4K and you want a balance between price and performance,DC 4K120 andGodlike 4K Pro deliver 4K up to 120Hz, 2K up to 240Hz and 1080p up to 360Hz — excellent coverage for most competitive monitors.
The highest refresh — Dichen DC1A686, Baan 7th Gen and DC505DHC
For anyone who wants the highest possible refresh rate, Dichen DC1A686 is our highest-refresh fuser: 4K@164Hz, 2K@364Hz and 1080p@639Hz over DisplayPort 1.4, for less than the Baan or DC505. AndBaan 7th Gen RGB reaches 4K@144Hz and 1080p@480Hz, andDC505DHC delivers high performance at every resolution. This tier is for serious gamers and owners of high-refresh monitors.
How to choose?
- 2K monitor and a limited budget: Fuser Dichen 2K
- 4K monitor and a price/performance balance: DC 4K120 or Godlike 4K Pro
- High-refresh monitor and maximum performance: Dichen DC1A686 (highest refresh), Baan 7th Gen or DC505DHC
The simple rule: choose a fuser that supports your monitor's maximum refresh rate. A 4K@144Hz fuser is pointless if your monitor is 2K@165Hz — and the reverse: don't buy a fuser that cuts your monitor's refresh rate.
FAQ
Is a fuser necessary in a DMA setup?
Yes, it's the device that merges the display signal between your two PCs and outputs it to a single monitor at high resolution and refresh rate.
What's the difference between a 2K and a 4K fuser?
A 2K fuser is enough if your monitor is 2K, while a 4K fuser supports the higher resolution and suits newer monitors. Choose based on your monitor's resolution.
Is a higher refresh rate always better?
Only if your monitor supports it. The fuser should match your monitor's maximum refresh rate, no more and no less.
