Coby TFTV4028


At CES this year, Coby had an enormous sign and a nice booth right in the center of the show floor, so we thought to ourselves, maybe this company is stepping it up this year. Maybe we should give them a shot, and see how they compare against the...

It’s big and cheap

One of the worst viewing angles on the market ; Poor gamma detail ; The black level is not very deep

The TFTV4028 ($600 MSRP but found much cheaper several places online) is a 1080p LCD display from Coby with limited features. We thought to give Coby a shot after their huge display at CES this year.

Coby TFTV4028


The Coby TFTV4028 is a good economical alternative LCD TV for watching action movies, sports and video games because of the respectable refresh rate and response time. It is a less ideal option for buyers who are looking for high contrast and color...

This LCD TV has two USB ports

Despite the smaller screen, this television is one of the thickest we reviewed

This LCD TV suffers from a dismal contrast ratio, high wattage consumption and small screen.

Consumer review (

Dead spot on arrival.


RMA seems cumbersome for Coby. TVs over 33" are treated at home, maybe I'll give a better review if the customer service is good.

Good price

Sound quality is very low. SD video quality is ok at best. Big dead spot on my screen right out of the box, very noticeable. There's a dead pixel inside of a bunch of what seem to be stuck pixels
