HUGE WARNING!! See at the end of the postI am a photographer who needs to have true colors and be able to straighten verticals and perspectives. I wanted to try a curved screen so began my journey to replace a 27" iMac screen with a 34" to avoid purchasing two monitors.After hours of research and returning an LG 34UM88 34" monitor, decided on this one based on reviews from many different sources. Many had written Wow!, Amazing!! but that was not my first impression. After first turning it on, I was underwhelmed. The screen is big, nice curve and easy to hook up, but I thought it was rather dim and contrast was low (whites and blacks were not really white or black but bluish and gray). I didn't want to change the factory setup as supposedly it is calibrated. However, I did start adjusting by going through the monitor presets (Standard, Movie, ComfortView, Multimedia, Gaming, Color Temp and Custom Color).I found that the ONLY preset that would help to boost the brightness and contrast to my liking was the Gaming Mode, which enables Dynamic Contrast. I am satisfied at this point in that I was able to achieve a true white and good contrast. Although one site Digital Trends reports the contrast on this monitor is less than the previous model (3415).So, one day later, I am satisfied and now have a view that could be described as outstanding. I don't understand others that have said the monitor was breathtaking right out of the box. Perhaps I received an anomaly, who knows. I don't have a photo shoot for a day, but will post again if anything changes. Especially in answering the question whether a curved monitor is ok to work with for architectural photography that demands straight verticals.BTW, I cannot find any Light Bleed or dead pixels. Looks like I got lucky. You could spend more and could spend less, but for the price, it is probably a keeper.Update: DO NOT BUY DIRECT FROM DELL! My experience was terrible with Dell. They did not update their website status at all, promised expedited delivery by the 6th (ordered this on the 16th of Dec), did not tell me they were having a part problem until I called and then said I wouldn't receive it until the 20th. I called and cancelled on the 9th but then received an email on the 11th stating that the monitor had been shipped. The price I paid was $849, but then there were two price drops down to $799 and when I called ask about getting a credit for the difference, was told the monitor would have to be delivered first, then I would have to call and request a credit.That's when I decided enough was enough. Did I mention that all the reps are hard to understand their English, which only irritated me all the more? I called and today after receiving the "your monitor has been shipped" email and was told it was too late to cancel and that they had no record of my call on Monday to cancel. Yikes!!!!!Meantime, last Monday when I cancelled (or so I thought), I ordered the same monitor through Amazon and received the monitor two days later. If you search Dell reviews, you will see thousands and thousands of bad reviews for their customer service. My advice? Don't go near them to purchase, go through some other reputable seller like Amazon.
