Detailed Comparison
Resolution: 1440p vs 4K
PG27AQDP (1440p): At 27", 1440p provides 109 PPI (pixels per inch). This is sharp enough for gaming without scaling. Text is clear, images look crisp. Most importantly, 1440p is much easier to drive at high frame rates.
PG32UCDM (4K): At 32", 4K provides 140 PPI - noticeably sharper text and more detail in games. However, 4K requires a powerful GPU (RTX 4080/4090) to hit high frame rates.
Winner for competitive gaming: PG27AQDP (easier to hit 300+ FPS)
Winner for visual quality: PG32UCDM (stunning detail)
Refresh Rate: 480Hz vs 240Hz
PG27AQDP (480Hz): World's first 1440p 480Hz monitor. At 480 FPS, frame time is 2.08ms - imperceptibly smooth. Perfect for CS2, Valorant, Apex where you can actually hit 400+ FPS.
PG32UCDM (240Hz): 240Hz is still extremely smooth (4.17ms frame time). For most gamers, the jump from 240Hz to 480Hz is less noticeable than 144Hz to 240Hz. Also, hitting 240 FPS at 4K is more realistic than 480 FPS at 1440p.
Reality check: Most gamers won't hit 480 FPS consistently. The PG27AQDP's advantage is marginal unless you're a pro with a top-tier PC.
Panel Technology: WOLED vs QD-OLED
PG27AQDP (WOLED with MLA+): Uses LG's WOLED panel with Meta Lens Array. This makes it 20% brighter than standard WOLED (275 nits vs 230 nits). Better for bright rooms.
PG32UCDM (QD-OLED): Samsung's Quantum Dot OLED. Slightly more vibrant colors, better text clarity (important at 32"), but marginally dimmer (250 nits).
Both: Perfect blacks, infinite contrast, 0.03ms response. OLED quality is exceptional on both.
Size Matters
27" (PG27AQDP): Competitive gaming standard. Entire screen visible without head movement. Fits most desks comfortably. Better pixel density at 1440p.
32" (PG32UCDM): More immersive for single-player games. 4K at 32" looks incredible. Requires more desk depth (sit further back). Some prefer this size for work + gaming combo.
GPU Requirements
For PG27AQDP (1440p 480Hz):
• Esports (CS2, Valorant): RTX 4070 / RX 7800 XT can hit 300-480 FPS
• AAA games: RTX 4080 for 200+ FPS on high settings
For PG32UCDM (4K 240Hz):
• Esports: RTX 4080 for 240+ FPS
• AAA games: RTX 4090 recommended for 120-240 FPS on high settings
Verdict: The 4K monitor demands more GPU power.
Price vs Value
At only £48 difference, both are similarly priced. The PG32UCDM offers more screen real estate and 4K resolution for just 5% more. However, the PG27AQDP's 480Hz is a unique feature you can't get elsewhere at 27" 1440p.
Who Should Buy Each Monitor?
Buy the PG27AQDP (£899) if you:
✓ Play competitive FPS games (CS2, Valorant, Apex)
✓ Want the smoothest possible motion (480Hz)
✓ Have a high-end PC that can hit 300+ FPS
✓ Prefer 27" screen size
✓ Want slightly better brightness (MLA+ tech)
✓ Are a serious esports player
Buy the PG32UCDM (£947) if you:
✓ Play a mix of competitive + single-player games
✓ Want stunning 4K visual detail
✓ Prefer a larger 32" screen
✓ Have an RTX 4090 or top-tier GPU
✓ Value resolution over extreme refresh rates
✓ Want 90W USB-C Power Delivery for laptops
✓ Use monitor for work + gaming (4K is better for productivity)
Our Verdict
For pure competitive gaming: ASUS PG27AQDP wins. 480Hz is overkill for most, but if you're chasing every advantage in esports, this is it.
For versatile gaming: ASUS PG32UCDM wins. 4K looks incredible in Cyberpunk, Elden Ring, and any single-player game. 240Hz is still extremely smooth. The larger screen is more immersive.
Best overall value: PG32UCDM edges ahead. You get 4K, larger screen, and USB-C charging for just £48 more. Unless you specifically need 480Hz for competitive edge, the 32" 4K is more versatile.
Alternative to Consider
If neither fits your needs, consider the Samsung Odyssey OLED G9 (£799) - a 49" ultrawide OLED at 240Hz for an entirely different immersive experience.
