UPERFECT GR19BU: what it gives up
- Three pounds and a 17-inch footprint is luggage, not a laptop-bag slip pocket
- It ships with its own power adapter because a 19-inch 4K panel asks more of a laptop port than a 14-inch one does — UPERFECT rates the monitor at 16 W and publishes no adapter figure
- UPERFECT publishes no HDMI version for the mini-HDMI input, so whether that input carries 4K at 144 Hz is unknown and the port table here leaves it out
- 9 ms grey-to-grey is slow for 144 Hz — smearing is visible in fast motion
- The HDR claim comes with no certification and no local dimming, so this page credits it with no HDR at all
- At around $480 it costs more than several 27-inch desktop 4K monitors
UPERFECT GR185CF: what it gives up
- 119 pixels per inch is 50 pixels per degree at arm's length — text looks soft next to a laptop screen
- 14 ms grey-to-grey means 120 Hz motion still smears
- No power passthrough, and an 18.5-inch panel asks a lot of a laptop's USB-C port
- 300 nits across a screen this size is dim in a bright room
