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 | ||
|---|---|---|
| 33.6 ms ... rise ↗ and fall ↘ combined | ↗ 19.2 ms rise |  |
| ↘ 14.4 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. » 89 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (21 ms). | ||
| ↔ Response Time 50% Grey to 80% Grey | ||
| 46 ms ... rise ↗ and fall ↘ combined | ↗ 23.2 ms rise |  |
| ↘ 22.8 ms fall | ||
| The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 77 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (32.9 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 | 2525 Hz | ≤ 25 % brightness setting |  |
The display backlight flickers at 2525 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 25 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 2525 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 8743 (minimum: 5 - maximum: 343500) Hz was measured. | |||

发烧友不可避免地会对XPS 13 7390 2合1的板载组件产生鄙视情感。尽管RAM，WLAN，甚至存储之类的关键规格不可升级很不可取，但Dell的目标受众对这些功能并不感兴趣。 这台XPS 13的目标是占领二合一笔记本市场，在该市场中，诸如Surface Pro之类的可拆卸产品在可升级性方面已经非常有限。
戴尔二合一最好的一点是其显示屏，而不是花哨的新英特尔Ice Lake-U CPU。从客观上讲，即使是最便宜的Core i3 SKU上的屏幕，也比价格昂贵数百美元的许多其他旗舰超极本的显示屏要好。它更亮，调色也是开箱即用，由于具有更高的16:10宽高比，甚至看起来更宽敞。如果您曾经想将13英寸二合一笔记本电脑用于旅行和户外使用，那么这将是您最好的选择，因为与竞争对手相比，显示屏的亮度更高。
至于酷睿i3-1005G1，其CPU性能仅比酷睿i3-8145U略强，同时在更高效的10 nm设计中提供相当于酷睿i7-8565U的集成图形性能。在这方面，两代间的升级是微不足道的，但是它仍然比旧的XPS 13 9365系列所提供的Core 7Y54或Core 7Y75更好。
我们的大多数抱怨都微不足道，但加在一起还是很恼人。局促的方向键，沾指纹的表面，缓慢的白黑响应时间，DPC延迟问题以及缺乏更高的刷新率和WWAN选项，这些都阻碍了Dell将其打造为终极二合一笔记本。 2017年型号的一些功能（如Noble Lock，红外摄像头和可移动存储）已全部删除。此外，在满负载下运行CPU将达到99°C的核心温度，这已经让我们担心Core i7配置的性能。用户可能想考虑的最接近的替代产品是14英寸HP EliteBook x360 1040 G5，这是我们所知的唯一提供WWAN的同类型笔记本，它具有超亮的120 Hz显示屏，可升级的存储空间以及更多接口选项，但却没比戴尔大多少。
由于我们在此零售设备上遇到了几个与硬件相关的问题，因此我们强烈建议买家在购买后立即检查是否有任何异常情况。失真的扬声器和USB C型电源问题是严重的问题，我们只能希望是由于运气不好而不是更多的原因。
13.4英寸XPS 13 7390 2合1是相对于2017 XPS 13 9365几乎在所有意义上的重大升级。它最大的惊喜不是新处理器，而是经过良好校准的显示屏，它比大多数其他超极本所提供的显示屏更明亮。但是，如果您愿意再多花一点，那么14英寸HP EliteBook x360 1040 G5几乎可以满足了XPS 2合1的所有功能，但具有更好的可升级性和更多的连接性。
