Display Response Times
ℹ
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 | ||
|---|---|---|
| 33 ms ... rise ↗ and fall ↘ combined | ↗ 15 ms rise |  |
| ↘ 18 ms fall | ||
| The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 88 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (20.9 ms). | ||
| ↔ Response Time 50% Grey to 80% Grey | ||

| 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. » 90 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (32.8 ms). | ||
Screen Flickering / PWM (Pulse-Width Modulation)
ℹ
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 | 200 Hz | ≤ 90 % brightness setting |  |
| ≤ 343 cd/m² brightness | |||
The display backlight flickers at 200 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 90 % (343 cd/m²) and below. There should be no flickering or PWM above this brightness setting. The frequency of 200 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below. 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 8710 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Eksiler
- Bakım zor
- Renk üretimi zayıf ve ortalama kontrast

- Rahatsız edici işlemci sesi
- Sınıf için ortalamanın altında batarya ömrü
HP'nin Elitebook 745 G3 modelinde aydınlığı ve karanlığı çok ufak bir çizgi ayırıyor. Açıklamak gerekirse, cihazın güçlü yanları yüksek kalite kasası, harika arayüzleri ve mükemmel ekranı. Uygulama performansı da oldukça iyi. SSD sayesinde cihaz oldukça hızlı tepki veriyor ve açılış ile yükleme sürelerinde oldukça hızlı. Carrizo işlemci gündelik kullanım için yeterli performansı sunuyor. Ancak A12-8800B işlemcinin mevcut Core i3 işlemci seviyelerine ulaşamamasını da eleştirmek gerekir.
HP'nin bakım kapağı ve USB portları ile ilgili tercihi konusunda biraz konuşmak gerekir. Ek USB Type C port geleceğe yönelik olsa da, port sayısının azaltılması yerinde bir karar değil. Kısa batarya ömrü, kötü webcam bu fiyat aralığındaki bir cihaz üzerinde iyi durmuyor.
Ne kadar ekmek o kadar köfte sözü bir kere daha doğru çıkıyor. Elitebook 800 serisine kıyasla düşük kalan fiyatın sebeplerini anlamak mümkün. Ama bu hiçbir şekilde 743 G3 modelini kötü bir cihaz yapmıyor.
