Dobrý den, jaké je skutečné fps? uvádíte 240Hz, ale mně Windows nepustí na více než 60Hz. Zkoušel jsem několik kabelů a žádná změna.

The Epson EB-FH54 projector uses 3LCD imaging technology to display content in a native resolution of 1920 × 1080 Full HD. Its light source is a UHE lamp, which produces a luminous flux of 4100 ANSI lumens in normal mode for a clear picture even in well-lit rooms. The Full HD projector offers a scalable screen size from 31" up to 304". A high contrast ratio of 16000:1 helps with the legibility of details and the rendering of deep black shades. As a wireless projector, it supports content sharing from various devices via Miracast or AirPlay 2, expanding presentation possibilities without the need for a wired connection.
The 3LCD technology displays an image with a native resolution of 1920 × 1080 pixels in a 16:9 aspect ratio. The luminosity in normal mode is 4100 ANSI lumens, dropping to 2300 ANSI lumens in power-saving ECO mode. A high contrast ratio of 16000:1 contributes to text legibility and detailed display of dark scenes. The screen size can be adjusted from 31" up to 304", so the projector can adapt to different sized spaces, from small meeting rooms to larger halls.
Thanks to its short throw distance with a projection ratio of 1.30–2.09:1, the projector is also suitable for smaller spaces, where it can create a large image from a short distance. It projects from a distance of 0.88 metres to 14.3 metres. Image geometry adjustment is simplified by automatic vertical keystone correction within a range of ±30°. The manual 1.62× zoom is used to precisely adjust the image size without needing to move the device. The projector can be installed on a table, on the ceiling, or as a freestanding unit.
The projector works with a 230W UHE lamp. Its lifespan reaches 5500 hours in standard mode. When the power-saving ECO mode is activated, the lifespan of the light source is extended to up to 12000 hours, which reduces operating costs. The fan noise ranges from 37dB in normal mode to 28dB in ECO mode. The device's power consumption is 284W, or 181W in the power-saving setting, which contributes to lower energy consumption.
The projector supports smart features like screen mirroring. For wireless content sharing from mobile devices, it has support for Miracast and AirPlay 2 technologies. To connect signal sources, there are two HDMI inputs, a USB 2.0-A port for direct file playback, and a USB 2.0 Type-B port for service. Audio output is provided by a stereo mini-jack connector. The iProjection app further expands control and content-sharing options.
Epson is a technology company based in Japan. It is a subsidiary of the Seiko Group, and on of the most important manufacturers of printers, scanners and multimedia projectors. The company's offerings are much broader though, encompassing industrial robots, cash registers, and more.
