There is no A-TW polarizer on this panel which is rarely used now in the market but was implemented on some older screens to improve the off centre black viewing. By cloning the output, the user could provide a comparative test of the output of the CRT vs. This deviated as low as 2. The edges of the screen are a little rounded, more so than the rather straight lined UH in fact. Click for larger versions There is a useful cable tidy hole in the stand as you can see from the images above. These are located on the right hand side of the screen and work well.

In bright images, the backlight is increased, and in darker images, it is decreased. Testing the screen with various colour gradients showed fairly smooth transitions with some slight gradation in darker tones being evident.

The height adjustment range is very good. However, in practice you are never going to be able to see a DCR range like that. It’s not something you’d notice in practice, and you do have to look very closely to see it. The screens are u2212bmc marked as green winner or red loser in each category which should be self explanatory.

Our colorimeter recorded maximum luminance as However, if you change those setting manually it will prompt you and tell you that in doing so, the DCR function will be disabled.

In theory, brightness and contrast are two independent parameters, and good contrast is a requirement regardless of the brightness adjustment. Since most users won’t have access to hardware colorimeter tools, it is depl to understand how the screen is going to perform in terms of colour accuracy for the average user.

At maximum brightness the luminance was recorded at This might be more suitable for those working in darker lighting conditions del who are sensitive to brightness of screens although both screens should be fine given their backlight adjustment range.

There is a single connection for Dell’s sound bar if you want to add some speakers to the screen. This does make it a little more expensive than some TN Film based models in this sector of course, but for an IPS panel with very good all round performance depl is a good price.

Preset Modes – There is a ‘game’ preset mode available in the menu if you want it. The u2212hmmc responsiveness of both of these is ahead of the UHM, and the Hz frequency allows for improved fps frame rates and the support of 3D content as well.

Dell have included a 4 port USB 2. The older UH model showed a slightly more noticeable blur, but u22122hmc free from the de,l overshoot artefact. The picture is clear and the screen is large enough for our needs. I’ve also included a comparison above against two gamer-orientated screens, both featuring heavily overdriven TN Film panels, and Hz technology. There is some minimal overlapping of the text across sub-pixels as you can see in the photo which results in this blurring.


This made the image a lot cooler than the standard mode which is probably not very useable I don’t think. One person found this helpful.

Well worth a look I think. Please try again later. Squarer edges and thicker profile.

That being said I love everything else about it, and I don’t really notice it too much. They all show a low level of motion blur and a small dark overshoot when the overdrive function is turned on.

The UHM has more rounded edges to the bezel and stand compared with the rather square appearance of the UH. There was a problem filtering reviews right now. We also measured the colour temperature of each of the named preset modes as shown above. Colour accuracy calibrated – nothing really to separate the two once calibrated. The edges of the screen are a little rounded, more so than the rather straight lined UH in fact.

Not really anything in it in practice as neither work properly. In standby the screen uses only 0.
