6 Reasons For

Vivitek Has Good Reviews for Its Projectors

Projectors manufactured by Vivitek are some of the better projectors according to average expert and user reviews.

Supports 3D Image Projection

Unlike most of the other data projectors that came out in the last year which do not support 3D image projection, the Vivitek DX831 supports 3D image projection.

We compared this multimedia projector to all the other data projectors which support 3D image projection and we think because of it's better review score, the Benq HT2050[plb_3833255_price] is also worth considering.

Has a Built-In Speaker

Like most of the other new similar spec projectors, the Vivitek DX831 has a built-in speaker.

There are a number of alternative data projectors with a built-in speaker currently available that you might also want to consider including because of it's better review score, the Epson Home Cinema 1040[plb_3842831_price], or the Benq HT2050[plb_3833255_price].

Fairly Bright Projector Brightness

At 4,500 ANSI lumens, the Vivitek DX831 has a quite bright projector brightness compared to most of the other recently released data projectors. The dimmest projector brightness of 15000:1 contrast ratio projectors that are a similar age to the DX831 is 2,000 ANSI lumens, the brightest is 6,000 ANSI lumens, and the average projector brightness is 3,700 ANSI lumens.

Projectors with a brighter projector brightness that might also be worth considering include the DW832[pl_3704544_price] (5,000 ANSI lumens), or the DX977[pl_3704603_price] (6,000 ANSI lumens) both from Vivitek.

Three VGA (D-Sub) Ports

Most of the other similar spec data projectors that have been on the market for the last year only have between one and two VGA (D-Sub) ports, however the Vivitek DX831 has three VGA (D-Sub) ports.

Chart Edit

Two HDMI Ports

The Vivitek DX831 is a two HDMI port projector. Most of the other similar spec multimedia projectors that are a comparable age to the DX831 have between one and two HDMI ports.

7 Reasons Against

Does Not Support Full HD Projection

The Vivitek DX831 does not support Full HD projection. Most of the other projectors that are a comparable age to the DX831 do support Full HD projection.

We compared this multimedia projector to all the other multimedia projectors with a Full HD projection and we think the Epson U32+[plb_3673313_price] which also has a higher rating is also worth considering.

Does Not Support WiFi Connectivity

Most new 15000:1 contrast ratio projectors do not support WiFi connectivity. The Vivitek DX831 is no exception to this as it too does not support WiFi connectivity.

Other data projectors which also support WiFi connectivity that you might want to look at include the Epson U32+[plb_3673313_price] which also has a higher rating.

Only XGA (1024x768) Native Projector Resolution

The Vivitek DX831 has a maximum resolution of XGA (1024x768). That's 62% less resolution than a 1080p (1920x1080) projector, which is the most frequently found resolution.

This data projector's resolution (XGA (1024x768)) is actually the worst resolution amongst all 15000:1 contrast ratio projectors that came out in the last 12 months.

A WUXGA (1920x1200) native projector resolution is the best resolution across similar types of data projector.

Very High Running Costs

The DX831 has an average 1 year running cost of £136 based on typical energy prices and usage levels, which is in the most expensive 12% of all 18 new similar spec projectors.

Chart

Only One USB 2.0 Port

The Vivitek DX831 is a one USB 2.0 port projector. Most of the other latest multimedia projectors have between one and two USB 2.0 ports.

Chart Edit

Very Loud Noise Level

Recently released 15000:1 contrast ratio projectors have noise levels of between 29dB and 39dB. With a noise level of 39 decibels, the Vivitek DX831 has one of the loudest noise levels amongst comparable spec projectors of this age.

If you don't mind having a louder noise level then you might want to consider the EB-W04[pl_3047173_price] (37dB), the EX3240[pl_3184266_price] (37dB), or the S31+[pl_3368804_price] (37dB) all from Epson.

The Vivitek DX831 has one of the higher power consumption in economy mode (320 Watts) amongst data projectors of this age.
