| The screen shows good response rates in our tests, but may be too slow for competitive gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 50 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (21 ms). | ||

| The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 37 % of all devices are better. This means that the measured response time is similar to the average of all tested devices (32.9 ms). | ||
Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 1000 Hz | ≤ 23 % brightness setting |  |
The display backlight flickers at 1000 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 23 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 1000 Hz is quite high, so most users sensitive to PWM should not notice any flickering. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8734 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Den portabla Lepow-skärmen har utmärkt konstruktionskvalitet, särskilt med tanke på det låga instegspriset. Den är lätt och tillräckligt liten för att kunna bäras runt tillsammans med en laptop, precis som en vanlig surfplatta. Skärmen är bra nog för surfande, datainmatning och visst spelande även om vi tycker att lite mer ljusstyrka och kontrast hade gjort upplevelsen mycket bättre.
Det som är opraktiskt är att den kräver två olika kablar för att kunna användas. Även om alla kablar som behövs ingår i förpackningen är det ändå krångligt att behöva bära runt på en USB Typ C till Typ A-kabel och en mini HDMI-kabel. Skärmen behöver kontinuerligt dra ström från din laptop vilket förstås kommer påverka batteritiden på din PC eller MacBook. En Thunderbolt 3-port eller ett inbyggt batteri hade minskat röran genom att ta bort behovet av två kablar, så som på Odakes 4K-monitor.
