Manual of product V-4EX
Editorial note
The Roland V-4EX stands out for its exceptional image quality, thanks to its Full HD resolution and support for various video modes, providing an immersive visual experience. Connectivity is also a strong point, with two HDMI outputs that allow for connecting multiple devices. The built-in LCD screen makes the device easy to use while offering clear and precise display quality. Its modern and sleek black design easily fits into different environments. However, the product has some drawbacks. The lack of Ethernet/LAN connectivity limits networking and remote control options, which can be a disadvantage for some users. Additionally, the resolution of the built-in screen at 320 x 240 pixels is relatively low, which may affect display clarity for certain tasks. The absence of a mounting grid can complicate installation, requiring alternative solutions. Finally, with a weight of 2600 g, the V-4EX may be considered heavy for a device intended to be portable, making its use in the field less practical. In summary, the Roland V-4EX is a high-performing device with interesting features, but it is important to consider its limitations in terms of connectivity and portability.Score details
