No downside to FreeSync version with G-Sync compatibility, input lag significantly reduced in new firmware as well2/18/2019 10:51:38 AM

Pros: I've owned the 34GK950F for a few months now and I'm very impressed with it. Originally I had it paired with a Vega 64, but recently switched over to a 2080 Ti now that Nvidia is offering G-Sync compatibility with FreeSync monitors. I've had zero issues with the G-Sync compatibility, everything works just like it did with the Vega.

Cons: Light bleed is a lottery. However, my unit has no issues in this regard, on par with other IPS displays I've owned.

Overall Review: As of the firmware update released recently, there is really no advantage to getting the G-Sync version of this. Input lag is now down to 4ms, on par with the G model (check TFTcentral). With the F model you also get 144 Hz, HDMI 2.0 connectivity, and a pre-calibrated screen with additional sRGB preset.

Great for gaming, but that's about it11/18/2015 8:19:37 PM

Pros: Minimal blacklight bleed, no dead pixels. Good build quality, no glossy bezels Clean and easy use to OSD interface. 165 Hz feels amazing - liquid smooth. Arrived in the box pre-assembled which was a plus also.

Cons: Poor screen uniformity. There is a significant variance in luminance when looking at the top 1/3 of the display. This means that whites look darker in comparison to the middle and bottom areas of the display. In my experience, this is a non-issue for gaming, but for daily desktop use it can be distracting. When browsing bright web pages with a white background, for example, it looks like a dark cloud is covering part of the screen. This may just be my sample - regardless, a lot of other people have also noticed this so it is potentially widespread. I plan on returning this monitor for now and will revisit a purchase when/if Asus steps up its QC.

Overall Review: Giving it 3/5 stars as the PG279Q does excel at being an gaming monitor. If that's all you plan on using it for, it's a great display. However I can't recommend it for daily use, and especially any color work - the uniformity issues were severe compared to my LG 34UM95.

Monitor shipping with broken firmware4/7/2014 4:15:33 PM

Pros: Lots of screen real estate, great for programming work Calibrated well out of the box

Cons: See below.

Overall Review: Be warned that some basic functionality is broken on this monitor currently. Sometimes your computer will boot to a half screen and get stuck on a black screen when entering sleep mode or changing resolutions. For a product targeted at professional use these issues are very annoying and not acceptable for a $2300 display. While Dell has a firmware fix, they refuse to release it as a user-installable update. You will have to exchange your brand new model for a refurbished one to get the flashed firmware. There's a review on Anandtech confirming all this: "The MST feature on the Dell UP3214Q started out working poorly for me. It didn't wake up from sleep and the other issues I mentioned. A firmware update from Dell seemed to resolve all of these. It always woke up from sleep and the color profiles managed to stay in sync as well. " With LCD being an imperfect technology this exchange process can end up beging a huge hassle. I was content with my display otherwise and exchanging it for a refurb might mean I'll get one back that has poor backlight uniformity or stuck/dead pixels (went through many monitor exchanges back in the day due to this). Until NEW units start shipping with the updated firmware, I'd avoid this monitor.
