    Picture is good but speakers are awful

    • Verified PurchaserVerified Purchase
    • My Best Buy® MemberMember

    I bought this TV largely because it had the best picture of the TVs that were on display in the showroom. The difference was very obvious, so I bought it and paid the premium for the Sony name. Once I got it home several problems showed up. 1) the speakers are truly pathetic; 2) implementing a sound system results in video/audio sync issues; 3) interaction with Vudu has problems; 4) can’t add new internet interfaces; and 5) the Media function can play songs from my PC, but the volume oscillates during playback and is very annoying, so I don’t use this feature. Sound Problems: I have never had to buy a sound system for my TV, until now. The speakers on this TV sound like a cheap 1960’s transistor radio with no bass and set to mono. They may actually be worse, but I haven’t heard a transistor radio in a long time, so I’m giving them the benefit of the doubt. So I bought a 5.1 surround system ($235). Then I started having video/audio sync issues. Looks like people are speaking a foreign language dubbed with English. You can influence this problem by manipulating the “AV Setup” menu selection – Digital Audio Out. The settings are Auto 1, Auto 2, and PCM. Auto 1 doesn’t support multiple channels and results in the worst sync issues, so I don’t use that one. The sound system I bought posited that an HDMI connection would provide the highest sound quality, so I started by using the HDMI 3- ARC connection. After a few weeks of irritation about video/audio sync issues, I contacted the Geek Squad (under warranty) and they said there really wasn’t anything they could do about TV to Sound System issues. They said I would probably have better results connecting via the optical cable. They were right. The results are better with an optical connection, but picture and sound sync issues still abound. Very annoying. Vudu Issues: Vudu is not licensed for Sony Bravia, so it’s fortunate the interface works at all. I have 3 issues: 1) 4K (UHD) movies will only play for a few weeks after you do a factory reset on the TV. Then they quit working. I bought a Roku stick ($59) to view my UHD movies from Vudu; 2) some movies on Vudu will play audio but no picture. The Roku stick fixes that also; and 3) Sound quality when getting streaming content from the internet is only marginally influenced by this TV. It apparently relies on the source. So if I want to hear good sound quality on a movie like Burlesque, I have to stream it thru my $99 Phillips Blue-Ray instead of my $550 Sony TV. The difference in sound quality is significant.

    Good for Movies, Better as a PC Monitor

    • My Best Buy® Elite MemberElite Member

    Using this as a PC monitor for work (video editing) and gaming (... ok, mostly just Overwatch). The Good: As a PC Monitor - Supports 4:4:4 and looks great on a Windows 10 PC. Text is nice and crisp, and the color accuracy is very good. It's an IPS panel, so even at an angle the image quality is very good. The TV itself is fairly light, enough so that I was able to attach it to my multi-monitor mount without issue. Gaming - Very low input lag compared to other TVs in this class and price range. has it at about 19.7 ms. Not as good as some of the higher end PC monitors out there, but good enough for me. Smart Functionality - App selection is sufficient, no Plex though. The apps that are available are quick and responsive. Dedicated Netflix and Youtube buttons on the remote are a nice bonus. Movies & TV - Motion blur is minimal, so fast moving footage looks great. Granted, it's not native 120hz, but the Motionflow tech is pretty good. HDR10 support really shines with 4k blu-ray. Can't comment on the sound as I don't use the tv speakers. The Not-So-Good: It loses a star for a couple minor issues. One being that black levels aren't uniform in darker scenes and images, but you likely won't notice it unless you look for that sort of thing. The second is that after powering on, it seems to default to a higher input lag mode when connected to a PC. If I change the input to a different HDMI and then back to the one my PC is connected to, it goes back to the lower lag mode. Tried a bunch of different settings, nothing seems to affect this odd issue. Happens every time I turn it on. Other than that I have 0 complaints.

    First Rate

    • My Best Buy® MemberMember

    I bought this after returning a slightly less expensive 43". The deciding factor was not the quality at HD or UHD but at SD. This TV displays classic movies wonderfully without dark corners, edges or muddy pixels that are typlically noticeable with b&w content on lower quality screens. The Bravia also connects to a media PC to play music and videos directly via WiFi. The Chromecast enabled TV I returned required uploading everything to Google. One thing I also noticed with this Bravia is it doesn't generate much heat (unlike the sets I've owned before that have died). As cynical as I am about how electronics are presented in the showroom vs. how they really are at home, I've had this for a week and am extremely pleased....while the ability to add more apps would be nice, the setup controls (sound, wifi, picture) and (most importantly) picture quality are excellent.

    Absolutely best screen for anywhere near the money

    • Verified PurchaserVerified Purchase
    • My Best Buy® Elite Plus MemberElite Plus Member

    I spent a lot of time evaluating different TVs at my local Best Buy stores. To be on the safe side, I also checked the most competent reviews online, and this model quickly stood out. Having used it now for a month, I found it to be even better than I thought possible. Both 4K and HD content looks better than on other TVs in this price range, and even OTA (Over The Air) Standard Definition material looks jaw-dropping as long as the bit rate for the channel is decent. Upscaling from a 1K ("Full HD") Blu-Ray player looks really good. This model is one small notch below the very best for watching in a completely 100% dark room. If that's how you watch, spend another $300 on the X900 series of the same TV. I always have some light on in the room, so I do not miss anything in the picture quality department. [I have 25 years of experience with professional video, so I'm a lot pickier than average.] And the remote is great also, it has Netflix and YouTube buttons for convenience, and operates Sony Blu-Ray players perfectly. Love it!

    Great PC monitor

    • Verified PurchaserVerified Purchase
    • My Best Buy® Elite Plus MemberElite Plus Member

    I did lots of research on TVs to use them as PC monitor and this was at the top was kind of skeptical to get a TV for my photo and video editing but man this set is awesome, colors, rendition, the inpit lag on this one is very very good, perfect for gaming (unless you are a professional gamer, which 99.99 of people are not) very surprised with sony on this set, the HDR os good but not great, menus are kinda dated, even my 280 dlls LG has more fancy menus but this Sony TV runs circles on image quality, has some little negatives of course but, im a happy camper, i love this TV, by the way for gaming and PC monitor get this model (x720e) the newer model(x800e) is not as fast and lag is higher.

    Beautiful TV, buy it

    • Verified PurchaserVerified Purchase
    • My Best Buy® Elite MemberElite Member

    I love this TV. I got the 43" version, and at that size you really don't need 4K and can find a set for much cheaper, but it's hard to find any quality sets that are 1080p nowadays. If you care about image quality, spend the extra money, this is a great value anyway. The 43" has a VA display, so you will get better contrast/worse viewing angles than the 48", which is IPS. The 48" also comes with an external power brick, so keep that in mind. The styling is awesome. Very slim and modern design. I watch all my programming using PlayStation Vue and other apps.The remote has a dedicated Netflix button as well. If you need a smaller TV for the bedroom or wherever else, this is the best one from what I've experienced and what I've researched online.

    It's a Sony, what else do you need to know!

    • Verified PurchaserVerified Purchase
    • My Best Buy® Elite MemberElite Member

    I've always appreciated Sony products. Doing a little research on this one (and with a little help from the Best Buy guy, who has one of these himself), it was pretty tough to steer away. This was a replacement TV for the bedroom. One of the big reasons I decided on it was the 'refresh rate' (the new megahertz term). Being that it is a 4K (UHD), with the HDR, it was perfect for when I watch sports. Although I have the big TV in the basement, it's great to know that when the other 3 in my house have the other TVs occupied, I can go to the bedroom and watch whatever; and know that the picture won't be an issue.

    Better then expected

    • Verified PurchaserVerified Purchase
    • My Best Buy® MemberMember

    This model uses different (IPS) screen technology then (VA) technology used by comparable Samsung TV sets. It displays clean, clear, bright colors, clean whites with no bluish tint which is a problem with other TVs. It is suited for well lit rooms, so windows in the room do not cause a problem. Did not need any adjustments... colors were natural, perfect right out of the box. One click to Netflix, one click back to TV function. Pleasing me, pleasing my wife. Five stars.
