Rated 5 out of 5 by from Super Picture! I bought this monitor after doing extensive research, and I'm glad I decided on this model........ had no problem with the setup, plugged it right into the display port.....Colors are amazing!

Rated 2 out of 5 by from Annoying On/Off Switch & Not the Best Picture That toggle switch annoys me EVERY SINGLE time I turn the monitor on or off. It hurts your finger since it feels unfinished and rough. The picture quality is not as good as my 8 year old LG 1080p either. So sorry I purchased this!

My current computer does not have a dp port. Is there any disadvantage connecting the monitor with an hdmi cable instead of a dp? Will I lose any image quality or other features by connecting with an hdmi cable?

Asked by: jp30
The HDMI port is a ubiquitous port that can be found in TVs, Set-Top Boxes, Blu-ray Players, A/V Receivers, gaming consoles, camcorders, digital cameras, and even some smartphones. You’ll also find it in most consumer desktop and laptop computers. No modern all-in-one is complete without an HDMI input that allows you to connect a gaming console or a set-top box to the computer so you can use its display for a second purpose. Both HDMI and DisplayPort can send high-definition digital video and audio from a source device to a display. HDMI can handle a single video stream and a single audio stream, so it can drive only one display at a time. A single DisplayPort interface can support up to four monitors at 1920x1200-pixel resolution each, or two monitors at 2560x1600-pixel resolution, with each display receiving independent audio and video streams. And since some GPUs can support multiple DisplayPort interfaces, you can daisy-chain compatible monitors to connect as many as six displays to one source. HDMI was designed primarily for consumer-electronics applications: Blu-ray players, TVs, video projectors, and the like. Despite the confusing cable specifications, it does things that DisplayPort can’t. Meanwhile, VESA designed DisplayPort to be the ultimate display interface for computers, so it complements rather than replaces HDMI. The question of which port is better is more a question of connectivity...^IFV

Prompt please, whether there is a fundamental difference in this model from the model 27UD69P-W? Are the matrices identical? HDR is achieved by a chip(microprocessor)?Does it make sense to wait for this model or should I look at other models(competitors).
