Optoma Has Good Reviews for Its Data Projectors
Data projectors made by Optoma have an average rating of 88 out of 100, which is in the top 22% of all multimedia projector manufacturers that we have assessed.
Supports 3D Image Projection
The ML750ST supports 3D image projection, as do most of the other 20000:1 contrast ratio multimedia projectors that came out in the last 12 months.
We compared this projector to all the other projectors which support 3D image projection and we think a cheaper data projector such as the Acer H5381BD or you might consider a better rated data projector such as the Acer P6200 are also worth considering.
We compared all the other projectors which also support 3D image projection to this multimedia projector and we think the Acer X1378WH is also worth considering.
Has a Built-In Speaker
Like most of the other new 20000:1 contrast ratio multimedia projectors, the ML750ST has a built-in speaker.
Other projectors with a built-in speaker currently available which you might also want to consider include the Acer H5381BD which is cheaper; or the Acer P6200 which has a better Rating.
Other projectors which also have a built-in speaker that you might want to consider include the Acer X1378WH.
Very High Maximum Vertical Synchronization
Across all the multimedia projectors that were launched in the last 12 months the maximum vertical synchronization range from 0.12kHz to 120kHz. The maximum vertical synchronization of the Optoma ML750ST of 120 kilohertz is one of the highest amongst data projectors that have been on the market for a comparable time to the ML750ST.
Very Long Lamp Service Life
The average lamp service life of comparable spec projectors that are a similar age to the ML750ST is 6,400h. When compared to other newly released 20000:1 contrast ratio multimedia projectors that we have checked, the ML750ST's lamp service life of 20,000 hours is one of the longest.
+4 More reasons for
When compared to other new 20000:1 contrast ratio multimedia projectors, the ML750ST's weight of only 420 grams is one of the lightest. Across all the projectors that have been around for a similar time to the ML750ST the weights range from 420g to 17kg.
The ML750ST is one of the narrower 20000:1 contrast ratio multimedia projectors that have been on the market for the last year (only 112.5 millimeters) amongst 20000:1 contrast ratio multimedia projectors of this age. The average width of 20000:1 contrast ratio multimedia projectors that are a comparable age to the ML750ST is 310mm, and the widths range from 90mm to 500mm.
Quite Quiet Noise Level in Economy Mode
At only 22 decibels, the Optoma ML750ST has a very quiet noise level in economy mode compared to most of the other latest 20000:1 contrast ratio multimedia projectors. The noise levels in economy mode of 20000:1 contrast ratio multimedia projectors that have been available for a similar time to the ML750ST range from 22dB to 33dB.
7 Reasons Against
Only 50Hz AC Input Frequency
This projector has a 50Hz AC input frequency, which is the most frequently found AC input frequency on similar spec multimedia projectors that have been on the market for around the same time as it.
Does Not Support Full HD Projection
The ML750ST does not support Full HD projection. Most of the other data projectors that are a similar age to the ML750ST do support Full HD projection.
There are a number of alternative data projectors which also support Full HD projection that you might want to consider including the H5381BD, or the X1385WH ($402.95) both from Acer or the Acer P6200.
Does Not Support WiFi Connectivity
The ML750ST does not support WiFi connectivity. Most of the other similar spec data projectors that have been on the market for around the same time as the ML750ST also do not support WiFi connectivity.
We think you might also be interested in other multimedia projectors which also support WiFi connectivity including the Acer P6200 which also has a higher rating.
Quite Dim Projector Brightness
The dimmest projector brightness of latest similar spec projectors is 800 ANSI lumens and the brightest is 5,400 ANSI lumens. When compared to other newly released data projectors, the projector brightness of the ML750ST of only 800 ANSI lumens is one of the dimmest.
If this 20000:1 contrast ratio projector projector brightness is too dim for you then you might want to look at the Acer X115H (3,300 ANSI lumens) which is also cheaper.
+4 More reasons against
Quite Low RMS Rated Power
Across all the projectors that have been around for around the same time as the ML750ST the RMS rated power range from 1.5W to 20W. The ML750ST has one of the lowest RMS rated power (only 1.5 Watts) amongst 20000:1 contrast ratio multimedia projectors of this age.
Only One VGA (D-Sub) Port
Most latest 20000:1 contrast ratio multimedia projectors have between one and three VGA (D-Sub) ports, including the ML750ST which has one VGA (D-Sub) port.
Only One HDMI Port
Most 20000:1 contrast ratio multimedia projectors that have been around for the last year have between one and two HDMI ports, including the ML750ST which has one HDMI port.
2 Other reasons to consider the Optoma ML750ST
Released Nine Months Ago
This projector has been on the market for nine months.
WXGA (1280x720) Native Projector Resolution
The ML750ST has a maximum resolution of WXGA (1280x720). That's 56% less resolution than the most common native projector resolution of 1080p (1920x1080).
Projectors with a higher resolution that might also be worth looking at include the LG PH550 ($389.98) (720p (1280x720 and higher rated) and higher rated); or the Acer H5381BD (720p (1280x720 and cheaper) and cheaper).

Total running cost over 5 years
Running costs for this projector have been estimated based on other similar projectors. If you know how much electricity and water the Optoma ML750STuses then please let us know by entering those figures in the boxes above.
Running this projector over 5 years will generate 0.14 tonnes of carbon dioxide (CO2).
To offset that much CO2 you would need to plant 4 tree seedlings and grow them for 10 years.
