Question: can i use this monitor to watch cable television with and also use it for pc or should i just by a tv and also use it as a monitor for my computer?
Document: There isn't a monitor out there that can provide this great of a picture for the price. It provides a clear image and looks sleek on my desk. I use it with my macbook and had no problem at all connecting it right away. You will need to buy a separate HDMI to Mini DisplayPort cable. I had one small issue, I cannot control the volume from my computer if it is coming out of the speakers in the monitor.
Why not instead put an HDMI and DVI slot instead? Maybe .01% of the buyers are going to use these in a dual monitor setup up. Also, the specs mention DVI in a very misleading way, it actually comes with a DVI to HDMI cable. My other ASUS monitor had a DVI port, so I had none of these issues.The monitor itself is quality, but there is a touch of cheapness to the plastic aluminum trim, but it's still a pleasing look.
If you can play your music or movies in a program with an equalizer, you can fine tune the sound to account for the muffled audio. I used VLC to watch a movie and adjusted the EQ to better suit the speaker design by boosting the highs and bass. I use iTunes for my music and was able to tweak the EQ to balance out the sound there also.Out of the box, there was no light bleed visible, images are even and well illuminated with reasonably accurate color.
I ordered this monitor to connect to a MacBook Pro with 15&#34; Retina Display. The computer has two Thunderbolt/Display ports and an HDMI port. I've tested it both with HDMI and a DisplayPort to HDMI adapter cable from Cable Matters.I have to say I did not have a high opinion of ASUS based on past experience. This monitor has changed my mind entirely.
Great price but 3 gripes:1.  the screen is not corner to corner. It's a monitor inside  a larger frame so it can claim it has no edges. Look carefully at the photo and you'll see the black 3/4 inch black.2. HDMI setup is super easy (it serves as the audio connection !) But either my computer doesn't read the HDMI cable audio feature or the monitor is no sending out the connection. I don't know.
Weird.The next two issues might have to do with the cable or with my own computer, and I'll update this if I ever end up checking it with another laptop... But the audio doesn't seem to work when connected to my MacBook Pro with a min-HDMI.
Selecting some resolutions shows my screen - but with flickering and an error message about an unsupported option. Taking the cable out and reconnecting it works sometimes, but not always. It's *probably* the cable or my computer, but given the almost complete lack of any user instructions, and the adventure with figuring out the buttons, I ended up extremely frustrated with the product.Anyway, it's all set up and working very nicely now!
Bought this having read the complaints about the speakers -the reviews were not wrong. The B&O speakers are rubbish, but the monitor is great. A perfect size to use if you always need to have multiple programs open at once. Since it has an HDMI input, surprised it doesn't come with an HDMI to HDMI cable.
Asus cut corners and made a few horrible mistakes with this monitor. You cannot use the audio-in 3.5mm connection if you're using an HDMI cable, even if you disable HDMI audio on your desktop and enable your sound card's 3.5mm audio out. Other Asus monitors allow through the menu system to disable HDMI audio on the monitor so the 3.5mm audio can be used, that is not the case with this monitor.
I went from an Apple Cinema display, and the biggest plus is the brightness.A few tweaks and this would be a smoking bargain, I just hate having to use such a dated analog connection for a modern computer monitor.
Answer: I cannot address directly your use of the display for cable TV, but I can tell you that my family and I use this monitor for watching Netflix all the time.  We got rid of traditional television years ago and use Netflix, Hulu and Amazon Video exclusively for our TV viewing.  Hard to imagine though that, with the proper HDMI-TV video adapter, this display will not do splendidly with your cable TV signal.  Enjoy!
