ViewSonic E790
1×VGA (RGBHV) (DE-15 (VGA))
The ViewSonic E790 is a 19-inch multisync colour computer monitor from ViewSonic's E2 Series, with an 18.0-inch viewable diagonal.[1]
The tube is a 90-degree deflection shadow-mask design with 0.26 mm dot pitch and RGB P22 phosphors of medium/short persistence. Its glass carries an anti-glare, anti-static and anti-reflective coating with a standard light transmission rate of 46%.[1] The default display area is 350 × 262 mm, with a full-scan area of 370 × 270 mm depending on signal timing.[1]
Sync range is 30–95 kHz horizontally and 50–200 Hz vertically, supporting resolutions up to 1600 × 1200. ViewSonic quotes maximum non-interlaced refresh rates of 1600 × 1200 at 76 Hz, 1280 × 1024 at 88 Hz, 1152 × 870 at 103 Hz, 832 × 624 at 106 Hz, 800 × 600 at 146 Hz and 640 × 480 at 180 Hz.[1] The monitor ships pre-adjusted to the VESA 1024 × 768 at 75 Hz and 1600 × 1200 at 75 Hz timings.[1]
Features
Video is analog RGB at 0.7 Vp-p into 75 ohms on an attached cable ending in a 15-pin high-density mini D-sub. Both separate TTL H/V sync and sync on green are accepted.[1] Compatibility extends to PCs and to Macintosh LC, LC II, Centris, Quadra and Power Macintosh systems, and INF and ICM colour-matching files were supplied on CD-ROM for Windows.[1]
A VIEWMETER function displays the horizontal and vertical frequencies of the incoming signal on screen.[1] The auto-switching power supply covers AC 90–240 V at 50/60 Hz through a 3-pin IEC320 inlet, typically drawing under 140 W in use, and DPMS power management gives under 15 W in stand-by and suspend and under 3 W when off.[1]
The monitor measures 452 × 465 × 468 mm (W × H × D) and weighs 24.5 kg. Approvals include UL, CSA, FCC, TÜV-Ergo/MPR II, CE, TCO 95 and Energy Star.[1]
