Q: On sony's site it says this tv has HDR. How come it says it doesn't have it on your site?

A: Hi Ryan, The Sony KD43X720E supports HDR content. -Jerome

Q: How wide is the stand for this TV? We have limited space. Thanks

A: Hi MarilynS, the width of the stand measures 22 1/4 inch (653 mm). Thanks. ~Ralph

Q: Can I use my standard HDMI cables or do I need 4K HDMI's, if that is really necessary.

A: I used my standard HDMI cables with NO problems. In my opinion the standard cables are fine unless you have excessively long cable runs; then you might want a "more expensive" cable. Also, if you are going to install the cable in the wall, you probably should use a cable rated for that application. This is more for cable protection than picture quality. I suspect that the "higher quality" 4K cable push is mostly marketing hype than technical.

Q: If I am going to use the RF connection to receive a standard broadcast,instead of HD broadcast, is the picture of this tv is gonna be so bad? Poor quality?

A: There is no such thing as a poor quality picture with a Sony TV. It will not upscale a SD picture but it will be very viewable.

Q: Just purchased this TV for our kitchen and can not find an internet browser on the TV OR anywhere to download it. On another Sony TV we own, there's access to the Google App store but this TV doesn't seem to have it! Help?!

A: Hi mcminer247, the Google App is only available on our Android TVs (XBR). You may try looking for the Opera app which is your TV's browser. Additionally, you may try downloading applications or a browser using the Opera Store app. Regards, -Mark

Q: Is this TV good for gaming? What's the input lag and motion blur like? Does it support HDR and will it run on Xbox One S/X, Ps4 pro and possibly a PC?

A: Yes, it supports HDR and Xbox One S and PS4 Pro both look and run fantastic. Motion handling is excellent, as with all Sonys.

Q: What soundbar would be compatible with this TV? I need clear dialogue so that the volume doesn't have to be really loud when there is action along with voices. My husband hates the loud noise.

A: The TV speakers support three features that will help you out in this regard. One is a dialogue boost setting that pumps up the volume of the human vocal range so that speech is louder than other sounds. There is also a dynamic compression feature that makes loud noises quieter and quiet noises louder, evening out the volume through your program's run-time. In addition, there is a setting to specify whether the TV is wall-mounted or on a stand, modifying the audio profile in each case to create clearer audio. While the TV speakers are mediocre on their own, I have found that adding a basic subwoofer and turning on the Subwoofer setting in the Audio Out options removes the need for a soundbar altogether.

Q: How do I open the web browser to type in the web address on this tv?

A: Hi Manolo, Though your TV is internet-capable and you can use it with certain applications, it doesn't have the internet browser function. For more details, kindly check this link: https://www.sony.com/electronics/support/articles/00138326 -Erin
