Large electricity company steps up in video conferencing

Ho Chi Minh Electricity Corporation replaces their videowall with a dnp Supernova Infinity screen in their meeting room. The goal is to make the daily video conferences with the head office a better experience for all participants in the large meeting room.

One big image instead of a broken-up videowall

Vietnams largest power company, EVN, contributes up to 58% of the national energy consumption from its large-scale hydropower and coal-fired power plants. Ho Chi Minh Electricity Corporation (EVN HCM) is one of five regional power distribution corporations, and every day EVN HCM reports to head office in video conferencing meetings.

To improve the quality of the daily meetings, EVN HCM wanted to replace their LCD videowall – the combination of several individual screens into one display – with one big quality display. So they turned to Nam Long AV for advice.

Difficult room conditions

“Image quality through videoconference is always a big challenge for any display because of camera quality. In this case we were also facing other challenges. The ambient light in the meeting room is very bright. Moreover, the viewing distance from the far end of the meeting table – the seat of the responsible manager – was quite long”, said Mr. Do Manh Ninh, CEO of Nam Long AV.

“From our experience, there is only one type of display that can get the job done if price is also a key issue. So we decided to use a dnp Supernova Infinity screen.”

Cost-effective solutions with ALR projection

There was a time, when video walls was the only way to produce a large image in a bright environment. With the new generation of Ambient Light Rejecting (ALR) projection displays, this is no longer the case. Combined with modern high-lumen projectors dnp Supernova screens can display bright and sharp images with no visible bezel lines. Moreover, projection is a very cost-effective alternative to big LED displays.

“Ho Chi Minh Electricity Corporation is pleased with the quality of their new video conferencing display. It is a big improvement and within a reasonable budget”, said Mr. Do
Manh Ninh.
