Hisense 4k Ultra Hd Smart Led Tv 50 Review
Out of the Box
As we exercise with all reviews nosotros manufactory reset the Hisense A7GQ and so measured the motion picture presets to detect the most accurate to the manufacture standards, out of the box, so we can view content as it was mastered and intended to be seen. On the A7G, this mode is Cinema Night with all unnecessary processing switched off manually and gamma fix to 2.half dozen, so it will track at two.iv. It would accept been squeamish to see Hisense supporting the Filmmaker Mode movement that well-nigh other manufacturers have supported for the last 24 months and we would encourage them to consider this for future models.

We use Calman colour scale software, a Murideo Seven Generator and Klein Thou-10A meter for measurement and calibration.
Out of the box, the greyscale results are reasonable for a TV at this price point and quality with some errors within the brighter stop of the scale. DeltaE errors are around 5 at the worst and rising just after 50% stimulus from the visible threshold of three with blue being too loftier in the mix and a lack of dark-green free energy every bit the greyscale gets towards white. Gamma tracks reasonably well towards ii.4, but nosotros had to utilise the 2.six settings in the menus to achieve this.
The Rec.709 color gamut results are also reasonable, but considering of the white balance effect, this has moved a few points abroad from being accurate. The near obvious error is with the hue of green every bit it tracks towards cyan and this is related to the gamut size and 100% greenish position. Nosotros should be able to fix this with the utilise of the CMS (Colour Management Organization).
Calibrated
The Hisense A7G has a suite of calibration controls available, but in all honesty, anyone ownership a £650 LED LCD TV is not going to vanquish out for a professional calibration. This is why we would push Hisense to be more accurate out of the box and add Filmmaker Mode. Nonetheless, nosotros volition calibrate the A7G to see but how accurate we can get information technology.
Every bit you lot can see in the greyscale results, we were able to get reference levels of accuracy and have gamma tracking perfectly to BT.1886. Our DeltaE errors were besides under ane, which is well under the visible threshold of three, pregnant no errors would be seen when watching Tv set and Film content.
We were also able to become very skillful results with the Rec.709 colour gamut with some balancing out of errors to get more accuracy, and without adding more force per unit area on the processing power of the TV by using too many corrections within the colour management system (CMS). While we withal have some errors at the 100% saturation level, such as light-green, magenta and bluish, from 75% and below nearly all the points were there or thereabouts. DeltaE errors were an average of 1.9 which is once again nether the visible threshold of three and not visible with Tv set and Movie content.
HDR Results
While the Hisense A7GQ is compatible with HDR10, HDR10+, HLG and Dolby Vision flavours of HDR, it is not really bright plenty to actually display HDR at its best. This is a mid-range LCD TV in the Hisense range and is rated at 300 nits by the visitor, so we set about measuring the peak brightness of the Television set as nosotros always do with various window sizes.
Equally you can come across, in the most accurate motion picture mode for D65 white, which is HDR Night, the A7G is merely capable of 250 nits brightness with all window sizes. This is what we would wait to see at this stop of the market and ways that the HDR flick operation, even in Dolby Vision, volition only accept a peak brightness of 250 nits before clipping.
The PQ EOTF in the HDR Night mode besides tracks correctly to the PQ EOTF standard ST2084 curve before difficult clipping at its meridian brightness of 240 nits. Other HDR moving-picture show modes may expect brighter but they practice not follow the PQ EOTF standard and push brightness, which just makes images look flat and brilliant with no dynamics or pop.
The DCI-P3 colour gamut inside BT.2020 does reach the claimed ninety% coverage with the saturation tracking too doing a decent job of aiming for accuracy with WCG content. This is a squeamish result that is rarely seen at this level of the marketplace and ways that colour errors in the most accurate HDR Night style are small, giving a good representation of the HDR content for broad color.
We measured BT.2020 at 65% XY and 69% UV with P3 coming in at 91% XY and 93% UV.
This is a nice result that is rarely seen at this level of the market
