According to the specifications, the **Philips Evnia 27M2C5501** is a 27″ QHD (2560 × 1440) monitor with the following maximum refresh rates:
* Via **HDMI**: up to **144 Hz** ([Philips Ireland][1])
* Via **DisplayPort**: up to **180 Hz** ([Philips Irlanda][1])

Whether and how many Hertz you can actually realise with an integrated **Intel UHD Graphics 630** depends on several factors - especially on the interface (HDMI or DisplayPort), the mainboard / graphics output, and the cable used.
A few important tips:
1. according to Intel specifications, the UHD 630 has a maximum support of 4096×2304 at 60 Hz via DisplayPort. ([Intel Community][2])
2. often only a limited frequency will be possible via HDMI, especially if the HDMI port on your motherboard only supports version 1.4. In some cases, you are limited to 60 Hz or only slightly higher. ([Intel][3])
3. users report in forums that they were occasionally able to reach 100 Hz at 1440p with the UHD 630, but not beyond that. ([PCPartPicker][4])

**My assessment / answer:**
If your system (motherboard & GPU output) supports **DisplayPort** and a suitable cable is used, you could well achieve more than 60 Hz in many cases - e.g. 100 Hz or more - as long as the UHD 630 and your system can handle the data rate.
If, on the other hand, you are only connected via **HDMI** (and especially with an HDMI 1.4 connection), it is very likely that you will have to stick to **60 Hz** or can only go slightly higher.
If you want, I can look into how many hertz is realistic for your specific motherboard / PC - would you like that?
