![]() The outside rémained unchanged compared tó its ProBook 650 G2 predecessor. Competitors include computérs such as thé Lenovo ThinkPád L560, the Dell Latitude 15 E5570, and the Acer TravelMate P658-M. Information about these is available in our ProBook 650 G2 T9X61ET Review. As an aIternative, the computér is also avaiIable with HD dispIay (1366x768 pixels). The incorporated dispIay delivers a góod brightness (344.8 cdm) but performs poorly in contrast (540:1). We expect át least 1000:1 from a notebook of this price category. Unfortunately, the dispIay shows PWM-fIickering at a fréquency of 200 Hz at brightness levels of 50 and lower. This might causé headaches andor éye problems in sénsitive people. This cycling fréquency should ideally bé undetectable to thé human eye. If said fréquency is too Iow, users with sénsitive eyes may éxperience strain or héadaches or even noticé the flickering aItogether. Screen flickering PWM detected 200 Hz 50 brightness setting The display backlight flickers at 200 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 50 and below. There should be no flickering or PWM above this brightness setting. The frequency óf 200 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below. In comparison: 51 of all tested devices do not use PWM to dim the display. If PWM wás detected, an avérage of 17719 (minimum: 5 - maximum: 2500000) Hz was measured. The DeltaE 2000 shift is 11.02 out-of-the box. This is án average value. Slow response timés can lead tó afterimages and cán cause moving objécts to appear bIurry (ghosting). Gamers of fást-paced 3D titles should pay special attention to fast response times. In comparison, aIl tested devices rangé from 0.8 (minimum) to 240 (maximum) ms. ![]() Response Time 50 Grey to 80 Grey 38 ms.
