Philips is back with a 23 inch 2 ms full HD screen, that includes DVI, VGA and HDMI sockets as well as a pair of 2 x 2 watt speakers. Nice looking and reasonably priced, it's well worth a look.

It is similarly designed to the 220CW9, with a glossy black bezel and base socket and a grey metalic base. The bezel is underlain with a grey bar to disguise the speakers and gives it a very nice finish. Philips has again included a 1 port USB hub. The base is the 230C1’s weak point. The panel can only be tilted a few degrees and there's no pivot mode or even any way of adjusting it vertically. If the sound quality given by the built-in speakers isn’t what you’d like, there’s a headphones socket just under the speaker bar.


Those who were expecting a good 2 ms will be disappointed. Bad management of overdrive induces a reverse ghosting effect, which means you’ll think twice before activating the 'Smart Reponse' function that is meant to cut response times down from 5 ms to 2ms. You have to make do with 5 ms. This is a pity because with a display delay of under 1 image the screen would have been a good choice for gamers if it were a real 2 ms.

Colours and contrast :

At start-up you don’t notice any colour dominance. This is confirmed by the sensor readings and the deltaE is under 2.7. This is an excellent score for a screen that hasn’t been reset. There are problems with the contrast however. The contrast ratio is hardly better than 500 : 1, where the average for screens is around 750 : 1. With decent levels of black, this screen would easily have scored four for colour quality. However we have had to take off a star instead.


As usual, there is virtually no upscaling and flickering is very visible and looks worse because of the lack of contrast. To optimise video, you need to be very rigorous in the choice of source and player that you use.
Watch out for bad habits!
In our last three tests on Philips 2 ms screens we discovered more or less marked reverse ghosting on each of the three models. This phenomenon appears when overdrive (an electronic technique for accelerating the movements of liquid crystals) is activated. Although the manufacturer may not notice such details, gamers may well end up boycotting the brand. Paying the price of a 2 ms for a 5 ms can obviously be disappointing.

For more details on reverse ghosting, see the inset in the page on the Philips 220CW9.


  • Default colour quality fairly accurate
  • Nice looking screen
  • VGA + DVI + HDMI


  • Reverse ghosting
  • Contrast: lack of depth in blacks
  • Fixed base
  • This 2 ms is pretty much on a level with 5 ms screens


This Philips will have problems with anything except office docs. If you’re wanting a screen for other usage, go elsewhere.
