• 240Hz refresh rate
Check Price on Amazon
Pros
✓ Sharp 4K picture at 27 inches
✓ 240Hz keeps motion smooth
✓ Perfect blacks and very fast pixel response
✓ 4.5 average rating from 233 Amazon ratings
Cons
✗ Burn-in is possible with static images
✗ HDMI version not stated in the title, so check the listing for console use

On paper, the ASUS ROG Swift OLED PG27UCDM is a 27-inch 4K UHD monitor with a 240Hz refresh rate, using a QD-OLED panel.

OLED is the main reason to look at this one: each pixel lights itself, so blacks are truly black and motion looks clean at high refresh rates. OLED gives per-pixel contrast and very fast response, but static HUD elements can raise burn-in risk over time, so vary your content and use the screen-saver and pixel-refresh features.

Amazon owners rate it 4.5 out of 5 across 233 ratings, so there is plenty of real-world feedback to read before you buy. The title does not state the HDMI version, so check the listing before assuming 4K at high refresh rates on a console.

Best for: players who want deep blacks and very fast response.

May not fit if: you leave static windows on screen for hours or play mostly in a bright room.

How to Choose the Computer Monitor 27 Inch 4K

Warranty and support

Check the warranty terms on the listing, and read recent reviews for notes on dead pixels, backlight bleed and support.

Resolution and size

Resolution decides how sharp text and games look at a given size. 1440p is a strong balance for most desks, 4K is sharper but needs a stronger graphics card, and 1080p is the cheapest option.

Refresh rate

A higher refresh rate makes motion and scrolling smoother. 144Hz is a good starting point for gaming, and 240Hz or more helps in fast shooters if your graphics card can keep up.

Panel type

IPS gives accurate colour and wide viewing angles, VA gives deeper contrast, and OLED gives near-instant response and perfect blacks. Choose by what you do most.

Ports and connectivity

Check for DisplayPort and HDMI, and for USB-C if you want a single-cable laptop setup. Look at the listing for HDMI 2.1 if you use a console.
