Test: Philips Momentum 436M6VBPAB 4K Skärm (Sammanfattning)

En 4K-jätte med HDR.

TV eller skärm? Det är den första frågan vi ställde oss när vi såg Philips Momentum 436M6VBPAB. Enheten saknar dock en TV-mottagare, vilket gör det tydligt vad skärmen är till för. Momentum har dessutom stöd för 4K och HDR, vilket är en intressant kombination. Läs vidare för att få reda på huruvida Momentum är lämplig för desktop-användning och hur den står sig i våra tester.

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM detected 22400 Hz ≤ 99 % brightness setting
≤ 700 cd/m² brightness

The display backlight flickers at 22400 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 99 % (700 cd/m²) and below. There should be no flickering or PWM above this brightness setting.

The frequency of 22400 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

Flickering occurs even at high brightness setting and may have an effect on the user during everyday use.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8702 (minimum: 5 - maximum: 343500) Hz was measured.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
9 ms ... rise ↗ and fall ↘ combined↗ 4 ms rise
↘ 5 ms fall
The screen shows fast response rates in our tests and should be suited for gaming.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 21 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (20.9 ms).
       Response Time 50% Grey to 80% Grey
14 ms ... rise ↗ and fall ↘ combined↗ 8 ms rise
↘ 6 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 24 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (32.8 ms).

Recension av skärmen Philips Momentum 436M6VBPAB 4K.

Philips Momentum 436M6VBPAB är en massiv skärm på 43 tum med stöd för 4K och HDR. Skärmen ser ut som en TV, men avsaknaden av en TV-mottagare avslöjar vad enheten är till för. Philips har designat 436M6VBPAB för användning tillsammans med spelkonsoler, som man vanligen sitter en bit ifrån. Således är 436M6VBPAB:s enorma skärm i det fallet välproportionerad.

HDR-film ser utmärkt ut men att aktivera tekniken i Windows är för tillfället omständigt och ibland begränsat. Vidare förhindrar subpixelstrukturen som Philips använder 436M6VBPAB från att användas som en stor desktop-skärm. Vi misstänker att de flesta som sitter framför ett skrivbord kommer att märka de slitna färgerna och suddigheten runt kanterna på små typsnitt. Dessutom kan 436M6VBPAB i huvudsak bara användas i en fast position och det finns ingen möjlighet att justera höjden. USB Typ C-porten med USB PD är dock ett välkommet tillägg samtidigt som den inkluderade fjärrkontrollen gör det lättare att använda 436M6VBPAB jämfört med att använda den inbyggda joysticken. I korthet är Philips Momentum en fantastisk 4K-skärm, men nackdelarna hindrar den från att vara så mångsidig som den hade kunnat vara.
