It is important to distinguish between piracy websites and legal streaming/downloading platforms. While the keyword implies searching for free downloads, many of those sites are illegal and unsafe. However, there are legal ways to get high-quality MKV and MP4 files.

Based on your search for specific resolutions, here is a quick cheat sheet for the best viewing experience.

| Device | Best Resolution | Best Format | Bitrate (Approx) | | :--- | :--- | :--- | :--- | | Old Feature Phone | 480p (3GP/MP4) | AVI or MP4 | 500 kbps | | Budget Android Phone | 720p | MKV (H.264) | 1.5 Mbps | | iPhone/iPad | 1080p | MP4 (H.265/HEVC) | 4 Mbps | | Laptop (13"-15") | 1080p | MKV (H.265) | 2.5 Mbps | | 42" LED TV | 1080p | MKV (H.265, AC3 Audio) | 5-8 Mbps | | Projector (100"+) | 1080p or 4K | MKV (DTS-HD Audio) | 12+ Mbps |

If you ignore legal sources and search for "Download Hollywood Movies in HD MKV" on free torrent or "watch online" sites, you expose yourself to significant risks.

Before you start downloading, it is crucial to understand the numbers. The "p" stands for progressive scan, which refers to how the image is drawn on your screen. The number refers to the vertical resolution (height) of the video.
