Which 27-inch QHD monitor fits your panel and desk setup?
Both are 27-inch QHD monitors with manufacturer-listed refresh rates up to 180Hz, but the setup details differ. Samsung's page for exact part LS27FG512ENXZA lists a VA panel and a height-adjustable pivot stand; Acer's US materials for UM.HX1AA.307 list IPS, tilt adjustment without height adjustment, and 180Hz over DisplayPort versus 144Hz over HDMI. Choose by your panel preference, input route, and stand needs, not an untested image-quality claim.

The buying question
Which model better fits a specific panel-type preference, connection plan, and need for stand adjustment?
The Samsung exact-part specification lists a VA panel and height, tilt, swivel, and pivot adjustment; Acer's US exact-part materials list an IPS panel, tilt adjustment, and no height adjustment. Acer's listed maximum refresh depends on input: 180Hz over DisplayPort and 144Hz over HDMI.
Quick verdict
Choose Samsung Odyssey G5 G51F 27-inch QHD Monitor if
- You prefer a VA panel and have confirmed the offer is the Samsung G51F part LS27FG512ENXZA.
- You need the documented 120mm height adjustment or pivot movement on the Samsung stand.
Choose Acer Nitro KG271U N3 27-inch QHD Monitor if
- You prefer IPS and do not need to raise the Acer screen with its stand.
- Your Acer connection plan uses DisplayPort for its listed 180Hz mode, or its listed 144Hz HDMI mode is sufficient for your setup.
When the recommendation changes
- If you plan to use HDMI with the Acer and expect 180Hz, its US store specification lists 144Hz over HDMI and 180Hz over DisplayPort.
- If you need to raise or pivot the screen using the supplied stand, the Samsung exact-part page documents those adjustments while Acer lists no height adjustment.
The differences that matter
Panel And Display Workflow
Samsung Odyssey G5 G51F 27-inch QHD Monitor
VA panel[1]
Acer Nitro KG271U N3 27-inch QHD Monitor
IPS panel[2]
What this changes: If panel type is an explicit requirement, the listed types identify which model matches it; they do not establish comparative image quality.[1, 2]
Panel And Display Workflow
Samsung Odyssey G5 G51F 27-inch QHD Monitor
Maximum refresh listed as 180Hz; input-specific maximum not stated on cited page[1]
Acer Nitro KG271U N3 27-inch QHD Monitor
180Hz over DisplayPort; 144Hz over HDMI[2]
What this changes: Acer's listed refresh depends on the connection used; Samsung's cited page does not support a per-input comparison.[1, 2]
Desk Adjustment And Placement
Samsung Odyssey G5 G51F 27-inch QHD Monitor
Height adjustable 120mm; tilt, swivel, and pivot listed[1]
What this changes: Height adjustment and pivot can matter when aligning or rotating the screen; Acer documents tilt but not height adjustment.[1, 3, 2]
Panel And Display Workflow
Samsung Odyssey G5 G51F 27-inch QHD Monitor
27-inch class, QHD 2560 × 1440[1]
Acer Nitro KG271U N3 27-inch QHD Monitor
27-inch, WQHD 2560 × 1440[2]
What this changes: Both sources list the same 27-inch QHD resolution class, so resolution does not decide this pair.[1, 2]
Best for your routine
A desk setup that needs height positioning or pivot from the included monitor stand
Best fit: Samsung Odyssey G5 G51F 27-inch QHD Monitor
Based on listed features, not comparative testing.
Samsung documents 120mm height adjustment and pivot on the exact part; Acer lists no height adjustment. Choose the Samsung only if those stand movements matter to your setup.
A buyer whose explicit display preference is an IPS panel
Best fit: Acer Nitro KG271U N3 27-inch QHD Monitor
Based on listed features, not comparative testing.
Acer identifies its exact part as IPS, while Samsung's exact-part specification lists VA. This is a panel-type match, not a claim that Acer has better image quality.
Value and trade-offs
One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.
If one current offer costs more, consider whether its documented panel type or stand movement solves a need in your setup; this comparison does not establish a value winner.
The available price history is too short and old to tell whether either current offer is unusually low. Compare current offers when you are ready to buy.
Limitations
- Samsung's cited product specification is a Colombia page for the same exact part number LS27FG512ENXZA. It supports the stated hardware specifications only; this comparison does not verify US-specific warranty, package contents, or service terms.
- No controlled comparison establishes which monitor has better image quality, motion handling, response behavior, or overall gaming performance.
- Acer's US store lists 180Hz over DisplayPort and 144Hz over HDMI. The Samsung page lists a maximum of 180Hz without a per-input breakdown, so the article does not compare its HDMI maximum.
Questions shoppers ask
Does the Acer stand raise the screen?
Acer's US technical specification lists adjustable display height as No. Acer's store specification separately lists a -5° to 25° tilt range, so tilt is documented even though height adjustment is not.
Can the Acer run at 180Hz over HDMI?
Acer's US store lists 180Hz over DisplayPort and 144Hz over HDMI for part UM.HX1AA.307. Check that against your connection plan before choosing this model.
