Pros & Cons
Pros
- OLED pixels switch off individually, so black levels are effectively perfect (1,500,000:1 stated contrast)
- 0.03 ms minimum response time keeps OLED motion crisp
- 5120 × 2160 resolution gives a huge 5K2K desktop at 124 ppi
- 1300 nits peak brightness gives HDR highlights real punch
- USB-C with DP Alt Mode and 90W power delivery handles video and laptop charging over one cable
- 98.5% DCI-P3 coverage delivers very rich, wide-gamut color
- 165 Hz maximum refresh is well above ordinary 60 Hz screens
- DisplayPort 2.1 UHBR13.5 gives plenty of bandwidth for high resolutions at high refresh
Cons
- Burn-in remains a long-term risk with static desktop elements, even with OLED Care features
- Driving 5120×2160 at 165 Hz needs a very powerful GPU and DisplayPort 2.1 or HDMI 2.1 bandwidth
- 275 nits typical brightness trails LCD monitors in bright full-screen scenes
- At 44.5 inches it needs a deep desk and a firm arm or stand (14 kg with stand)
- The 1300 nits peak is a short-duration figure, and sustained full-screen brightness is much lower
- Static office layouts with taskbars and toolbars are the weak spot for an all-day work screen
- DisplayHDR 400 True Black is the lowest OLED HDR tier
- No portrait pivot for vertical code or document work
