Både HX755 og HX855 lider naturligvis af de samme skavanker som enhver anden LCD-skærm med LED-sidebelysning. I større eller mindre grad. Det ligger lissom i teknologien.

Sony HX753 (HX755)
PICTURE QUALITY (2D) – Whilst the HX753 shares a lot of the same qualities of the 853 we looked at, it's not quite a facsimile and the less rapid backlight modulation of the model reviewed here results in a more typical LED/LCD TV type picture, which makes the 753 appear a little more digital than the more expensive model. Black levels were very decent with the 753 measuring at 0.052cd/m2 on an ANSI checkerboard pattern which is almost exactly what we noted with the 55HX853, using the same Klein K-10 meter, in the same conditions so contrast levels are good and hold up well in bright conditions owing to the use of a very effective filter. As a point of interest, engaging the Adv Contrast Enhancer didn't really make a difference to the measurements.
Though the black level is impressive, the sample supplied did suffer with some clouding problems that intruded with darker scenes, although this could be improved by utilising the control labelled Adv Contrast Enhancer. This is, in reality, the global dimming control where Low is actually the most aggressive setting, rather confusingly. Users will need to balance the use of the control with the fact that it will lose detail in very dark scenes owing to the imprecision of the system; in a perfect world we would prefer not to have used it but given the clouding issues it was preferable to lose a bit of detail rather than suffer unduly with them. While we're on the subject of screen uniformity, the Sony HX753 did show up some panel banding under panning shots, especially with bright or pale colour tones but we've certainly seen worse examples of this with other LED TVs but (on a topical note) we did see a fair amount when Andy Carroll came on in the England Vs Italy game at Euro 2012.
Uniformity issues aside, we were generally impressed with the quality of pictures which offered a very nice sense of accuracy and no little detail. As with the 853, panel response doesn't seem the swiftest so some may find the need to engage Motion Flow on one if its more conservative guises for fast moving action shot on video but, set up right, the Sony is a very good all-rounder.

Sony HX753 (HX755)
CONCLUSION – The Sony HX753 is a decent flat-screen television. We'd be more enthusiastic if the colour accuracy was that little bit better: it seems that slim LED-based LCD TVs are still bringing picture quality compromises to the table, and there hasn't been any real image quality improvement for a while now (traditional CCFL-backlit LCDs had no trouble in fully satisfying the HDTV colour requirements, whereas plasma televisions are still getting better and better, but aren't suitable for every room). However, that's really the only problem with the image quality, with everything else being very satisfactory for a display of this price point.
Priced at around £680, the Sony HX753 has no obvious performance lead over the variety of other similar LCD HDTVs on the market, but also no gigantic negatives either. It has good picture quality, a suitably low level of input lag for gamers, and enough internet-connected Smart TV features to please most users. It represents decent value for money, and is a solid choice for anyone in the market for a well-performing LED LCD TV.
