Question: I have a very good speaker system, so can the speakers on the monitor be completely turned off?
Document: The monitor is decent. And the price is good. But there are no speakers!I was about to mount it on a movable vesa mount. Works well. But speakers are a must in an HDMI monitor.
Wow.....27&#34;.....two HDMI ports.....allow me to work on multiple PC's by just changing the input! I am really liking this monitor.....has the audio output which allows me to connect my bluetooth Audyssey speakers.....really liking this monitor!
I was a little skeptical with this monitor at first. However, the price is within my price range so I took a chance on it. So far I am not disappointed at all. The monitor is very bright and delivered as advertise. I use my monitor primarily for email, internet and programming.The only thing that I don't like is the menu. It is not very intuitive and the buttons are difficult to reach.Nice to have: built-in speakers.
It works well and I'm very happy with it.Beside the price, I wish it has speakers and cmera come with it.
Shipping was fast . Received it 3 days after order .The box was opened and sealed back with scotch tape . Further on , the monitor screen protecting tape was messy , no instruction booklet comes with it ,only a CD .After connected to my PC , a couple of dark wave lines went across the screen and I could not adjusted in any way . This suggested me that this monitor is probably a bad one that had been returned and turned around to reship without carefully inspection.
I purchased this to use with my Surface RT and Surface Pro 2. It works great on both. I have my computer speakers plugged into it so I only plug one cord into the tablet for sound & picture and it works great.
This was an excellent buy for black friday, the picture on the monitor is crystal clear, and I was amazed at the size of the screen! It simple to use and connects to any laptop/computer/media system that allows the use of a HDMI cable. works flawlessly and am happy with my buy. A great gift or or investment to any consumer thats looking for a bright big screen for computing/working/gaming use.
Completely satisfied with this purchase as I'm unable to find shortcomings with the monitor. I use my PC mainly with Office and emails and certainly surfing the web--so cannot vouch for other capabilities. I dinged this one star lower for the difficulty I'm having getting a quad screen with the software &#34;Screen+&#34;. I've been busy so I haven't attempted with any seriousness to overcome this setback.
the screen's big and painfully bright as it is, so it's ok.no speakers, but i could plug in headphones to it if i wanted to, i suppose. i have headphones already connected to my machines. the buttons to switch modes etc are on the lower right hand underneath, could've been a little better marked/reachable, but oh well also.
I'm not sure if 4 stars is a fair review or not, but I feel it's important to note that I had to Google to get it to work right with my setup. The problem was that when connected to my ATI card, via HDMI, the screen was not full, even at the recommended settings. Furthermore, after following the online literature, it offered no fix.So, I turned to Google and found that I needed to tweak my LCD screen scaling from within my ATI/Catalyst software.
Answer: Yes...and really doesn't matter...because I am able to use the audio mixer in the control panel.  I am using very good external speakers as well.
