Out of the box the colour vibrancy was quite over the top. It was excessively bright and colours were more than intense, they were radioactive - especially the bright orange of the TrustedReviews colour palette. However after some manual tweaking I managed to get the monitor to display an acceptable picture that was more accurate and far easier on the eyes. Now most people will not have a hardware colour calibrator in their possession, especially those who will be looking at Dell monitors. In its stead though, you can at least do some calibration by eye to get the best from your purchase – especially when you’re spending this kind of money. Even going through the image optimisation wizard of your graphics card will reap large dividends.
To get the most from the monitor I actually had to spend quite a lot of time optimising it to find the right settings. The panel has a brightness rating of 450cd/m2 but I had to turn it right down to make it liveable with. I finally reduced the brightness right down to 7/100 and the contrast down to 46/100 – which made a major difference to performance. Adjusting the gamma settings also had a great impact, bringing out much more detail. Once done the brightness was manageable, the contrast was much improved too and colours were far more natural - it went from being a bad display to a pretty good one.
Once these tweaks were completed, the monitor gave a decent account of itself when it came to picture quality. In the DisplayMate tests the 256 Intensity Level Colour Ramp was pretty smooth though there was still some banding visible on the green colour. The Colour Scaling test showed even fading all across the board but also revealed a slightly dirty look to the colours on this test. The White level saturation and the Grey-Scale Compression tests showed that there was just about enough contrast on hand after tweaking, though I’ve seen better. Otherwise colours are good, particularly the reds, which are quite deep. Despite the higher pixel pitch text sharpness was very impressive, so text was fine.
Looking at a range of photos, there was a pleasing amount of detail visible, with the textures and ripples of a jacket visible on the 2707 that were less distinct on the 2407. It has to be said that simply being larger that my 24in screen helped here to a degree.
Moving to gaming, I pulled out the old stalwart, TrackMania Nations. The colours were accurate, quite neutral and the fast motion was handled adequately. Response time freaks might find cause to complain but I’d have no problems gaming on this monitor. I hooked up an Xbox 360 to test component and VGA. I discovered that the display cannot accept a 1080p input - 1080i is your limit. There is a 1:1 pixel option in the OSD but over component this created black lines down the sides and well as above and below, which indicates that it wasn’t actually 1:1.
