The Amzfast AMZG27F6U is the 27-inch 4K monitor that takes the top spot in this guide at £221.99. The listing describes a Fast IPS panel running 3840 x 2160 at 160Hz, switchable to 1920 x 1080 at 320Hz, with 1ms MPRT, HDR400, 93% DCI-P3 colour and two HDMI 2.1 ports alongside two DisplayPort 1.4 inputs. It carries 4.5 stars from 3,428 ratings, and the supplied star breakdown reads 77 five-star entries against 6 one-star.

The finding here is the reverse of the two listings that rank below it. Nothing in the AMZG27F6U's bullets asks you to believe a bigger number than its own specification table gives: the table's 160Hz matches the bullet's 160Hz, its 1000:1 contrast stands alone with no higher dynamic figure elsewhere on the page to contradict it, and 400 cd/m² appears in both the bullets and the spec block. The one entry that is plainly in the wrong place sits in the technical data rather than in the sales copy — the field labelled Network Connectivity Technology contains the dual-mode refresh list, which has nothing to do with networking. Everything on this page is taken from the Amazon listing for this monitor, not from testing we carried out.

## Questions people ask

**Does the Amzfast AMZG27F6U really run at 160Hz in 4K?**

Yes, as listed. The bullets describe dual-mode switching between 4K UHD at 160Hz and 1080p at 320Hz, and the specification row for Refresh Rate reads 160.

**What contrast ratio does the listing give for this monitor?**

The specification table says 1000:1. Unlike some listings in this guide, no bullet for the Amzfast AMZG27F6U claims a higher dynamic contrast figure, so there is nothing on the page for the 1000:1 to contradict.

**How many HDMI ports does it have?**

The bullets say two HDMI 2.1 FRL ports plus two DisplayPort 1.4 ports, for PC, PS5, Xbox Series X and laptops. The separate Hardware Connectivity field says only "HDMI" (as listed).

**What does the Network Connectivity Technology entry mean?**

It does not describe networking. That field contains "4K1K Mode: 320Hz for HDMI / DP, UD Mode: 160Hz for HDMI / DP", which is the dual-mode refresh list sitting in the wrong row of the specification block.

**Is the stand adjustable?**

Yes. The Amzfast listing gives 0-130mm height adjustment, -5° to 22° tilt, ±30° swivel and 90° pivot for portrait mode, plus TÜV-certified low blue light and flicker-free technology.

**Does it have built-in speakers?**

Yes. The listing describes built-in 4Ω 2W x2 stereo speakers, alongside 400 cd/m² peak brightness and HDR400 for highlights.
