Comparing the Lenovo Explorer and HP Reverb G2 VR headsets is like comparing apples to oranges. The Lenovo Explorer is a PC VR headset while the HP Reverb G2 is a Mixed Reality device, so they have very different strengths and weaknesses.

Let’s start with Field of View (FOV). The FOV of the Lenovo Explorer is 110° while that of the HP Reverb G2 is 114° which gives it a slight edge in terms of immersion. However, if you plan on doing more precision work such as designing or CAD modelling then a wider field of view may not be necessary for your needs.

When it comes to resolution, the Lenovo Explorer has 2880 × 1440 px compared to 2160 x 2160 px from HP Reverb G2 – making it the winner in this category hands down. This makes text easier to read and video look sharper when compared side-by-side. In addition, for gaming or 3D design applications, higher resolution can be beneficial but this also depends on how powerful your computer system is and what kind of graphics card you are using.

Minimum CPU requirement for both headsets are fairly similar; Intel Mobile Core i5 Dual-Core with Hyperthreading for Lenovo Explorer and Intel Core i5/i7 or equivalent AMD Ryzen 5 processor for HP Reverb G2 – meaning neither one has an advantage here due to its price point. However, when it comes to minimum graphics requirement things get interesting; Intel HD Graphics 620 (GT2) with Nvidia GeForce GTX 1080 or AMD Radeon RX 5700​for HP Reverb G2 being significantly better than Intel HD Graphics 620 (GT2) required by Lenovo Explorer – therefore giving HP Reverb G2 an edge in terms of GPU power needed to run games smoothly at higher resolutions & settings along with other demanding tasks such as CAD modelling or video editing etc.. Also note that Professional Workstation users can opt for higher end GPUs such as Nvidia Quadro P5200 or AMD Radeon Pro WX 8200​for their respective machines too! So if you're planning on using either headset for professional purposes then you should definitely consider getting one with better GPU requirements instead!

The refresh rate also matters when choosing between two virtual reality headsets and here both headsets offer 90 Hz refresh rate which is great! It means smoother visuals without any motion blur during intense gaming sessions or movies/videos playback - thus providing great level of comfort while playing games & watching movies etc., however some users might need even higher refresh rates so they should check other available options accordingly before deciding anything further!

When it comes to Room Scale capabilities then only one out of these two devices offers it: HP Reverb G2 offers 360 tracking room scale support whereas Lenovo Explorer doesn't offer any room scale features at all - thus making it difficult to walk around your virtual environment unless user goes out & buys external hardware such as Vive trackers etc., apart from that Operating Systems wise Microsoft Windows supports both headsets just fine - so no worries there either way!

From my own personal experience I found the visuals & overall performance of HTC Reverb G2 far superior than that offered by Lenovo explorer – however depending upon individual's budget & usage scenario people will end up picking up something different altogether but in my opinion if someone really wants best bang-for-buck virtual reality experience then nothing beats buying into an HTG Vive Cosmos Elite setup over these two models mentioned above because it offers complete freedom from cables along with much better display panels + processing power under hood too!
