9 Reasons For

Lenovo Has Good Reviews for Its Flatpanel Monitors

Medium monitors built by Lenovo have good ratings on average compared to other brands. We also checked the reviews for all LCD screens (not just medium monitors) and found that Lenovo also has good ratings across its entire range.

LED Display Type

This flatpanel monitor has an LED display type, which is typical of many flatpanel monitors of this type and age.

Other PC monitors that have an LED Display currently available which you might also want to look at include because of it's better review score, the AOC e2250Swdnk[plb_1364842_price].

Has a Built-In Speaker

The Pro2840m has a built-in speaker, unlike most of the other medium monitors that have been around for a similar time to the Pro2840m which do not have a built-in speaker.

We compared this PC display to all the other PC monitors with a built-in speaker and we think because of it's better review score, the LG IPS231P[plb_1766654_price] is also worth considering.

Very Many Display Colour Count

When compared to other PC monitors of a similar type and age to the Pro2840m that we have checked, the display colour count of the Pro2840m of 1,073.7 million is one of the most. The least display colour count of medium monitors that came out around the same time as the Pro2840m is 0.21M and the most is 1,100M.

Chart Edit

3840 X 2160 Graphics Resolution

The Lenovo Pro2840m has a maximum resolution of 3840 x 2160. That's over four times the resolution of the most frequently found graphics resolution of 1920 x 1080 (HD 1080).

This flatpanel monitor's resolution (3840 x 2160) is in fact the best resolution amongst all comparable spec PC screens that were released more than two years ago.

Chart Edit

At 369.3 millimeters, the Pro2840m has a quite big viewable height compared to most of the other flatpanel monitors of this age and type. The viewable heights of PC monitors of a similar age and type to the Pro2840m range from 28mm to 630mm, and the average viewable height is 310mm.

9 Reasons Against

Not 3D Compatible

The Pro2840m is not 3D compatible, although this is within the context that most of the other flatpanel monitors of a comparable spec and age to the Pro2840m are also not 3D compatible.

If you want a flatpanel monitor that is 3D compatible then you might also want to look at the AOC d2757Ph[plb_1515695_price], or the Asus VG236[plb_2030776_price] which also has a higher rating.

Chart Edit

Does Not Have an Integrated Card Reader

Like most of the other medium monitors that have been around for around the same time as the Pro2840m, the Pro2840m does not have an integrated card reader.

We compared all the other PC monitors which also have an integrated card reader to this LCD screen and we think the U2413[pl_1565290_price], or the U2713H[pl_1518815_price] both from DELL or the Acer DA220[plb_1606986_price] which is also higher rated is also worth considering.
