The SG-640 HD Pro 4K Full HD Dual display Satellite Receiver promises a lot: simultaneous HD and SD viewing, automatic network searches, and support for a wide range of codecs. After weeks of testing, I’m ready to share my comprehensive review, detailing both its strengths and weaknesses.

The SG-640 HD Pro boasts an impressive feature set. The dual display functionality is a real highlight, allowing for simultaneous viewing of different channels. The automatic network search significantly simplifies the initial setup process, automatically finding and adding new transponders. The support for multiple languages in the OSD is a welcome inclusion, catering to a broader user base. The ability to sort channels alphabetically, by favourite, or by satellite is very useful for organization. The inclusion of a USB port for software upgrades ensures the receiver remains up-to-date.

The receiver handles MPEG2 SD, MPEG2 HD, and h.264/AVC HD flawlessly, which is important for a wide range of channels and broadcasting standards. The Picture in Graphics (PIG) support adds a neat touch.

In terms of performance, the SG-640 HD Pro generally exceeded my expectations. Channel switching is quick and responsive, with minimal lag. The picture quality, especially with HD channels, is crisp and clear. The automatic network search functioned as advertised, consistently discovering new transponders. DiSEqC 1.2 support worked perfectly with my multi-satellite setup. The remote control is responsive and easy to use. However, I did experience some minor issues with the Electronic Program Guide (EPG) on a few channels, although it largely functioned without problems.

The 5000 channel programming capacity is more than enough for even the most demanding user. The 8 favorite group selection makes organizing your preferred channels effortless.

Pros:

• Dual display functionality (HD and SD simultaneous)
• Automatic network search for new transponders
• Excellent picture quality
• Responsive channel switching
• Supports various codecs (MPEG2 SD, MPEG2 HD, h.264/AVC HD)
• User-friendly interface and remote
• Software upgrades via USB
• DiSEqC 1.2 support

Cons:

• Minor EPG inconsistencies on some channels
• On-screen display could be slightly improved in terms of aesthetics

Overall, the SG-640 HD Pro is a solid and feature-rich satellite receiver. The dual display and automatic network search are particularly useful features. While there are some minor drawbacks, they are largely overshadowed by its strengths. If you’re looking for a reliable and versatile satellite receiver with a good balance of features and performance, the SG-640 HD Pro is a highly recommended option.
