Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 25000 Hz | ≤ 30 % brightness setting |  |
The display backlight flickers at 25000 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 30 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 25000 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 8705 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Pros
Cons
戴尔Latitude 5495可以是AMD Ryzen移动端中非常好的一款产品。这里的重点是“可能”，因为戴尔也在很多地方做错了。
首先要说的是：我们非常感兴趣的是Latitude如何利用Ryzen的性能潜力 - 这方面我们给出的评价是“非常好的”。 Latitude 5495能够击败其英特尔型号的Latitude 5490以及联想ThinkPad A485和HP EliteBook 745 G5等知名竞争对手。尽管Latitude的电池容量小于宣传的容量，但两者在电池续航方面也要差得多。除了这些优势，Latitude 5495还提供了一个非常快速的SD卡读卡器，一个强大的机身，具有良好的可升级性和不错的输入设备。此外，风扇在闲置时保持静音，而机身即使在负载下也不会变得很热。
有闪光点，也有阴暗面。这里的问题主要表现在屏幕上。屏幕模糊不清，平均亮度只有200 cd /m²。因为在明亮的室内环境中200 cd /m²甚至可能都存在问题。此外，屏幕表现出漏光并且其色彩空间覆盖不足。屏幕是最明显的问题，但不是唯一的问题。其机身比竞争对手更重，更厚，这可能解释了戴尔如何能够装入这么大的电池。戴尔Latitude 5495还缺少了我们期望在这个价格范围的商务笔记本电脑中找到的功能。例如指纹读取器，指点杆或背光键盘——这些功能仅作为昂贵的选项提供。雷电3也不可用，但在这种情况下甚至不作为选项（主要是AMD不支持雷电3）。此外，戴尔在SSD上偷工减料。对于短短12个月的标准保修，情况也是如此。
评价不好做：戴尔Latitude 5495有许多积极的方面，但也有许多缺点。
在这种情况下，我们很难推荐一种设备或建议购买它。戴尔Latitude 5495当然有其优势，但对于我们来说，屏幕只是一个缺点——但我们也知道许多商业客户往往有不同的优先级而不是屏幕质量。考虑到所有因素，我们可能更喜欢竞争对手联想ThinkPad A485和HP EliteBook 745 G5，尽管它们的电池续航时间不如戴尔。无论如何，AMD Ryzen的完美笔记本电脑尚未出现。
