Toshiba 65L9300U: A 4K HDTV With HDMI 2.0 Support

Results: Color Gamut And Performance

Color gamut is measured using a saturation sweep that samples the six main colors (red, green, blue, cyan, magenta, and yellow) at five saturation levels (20, 40, 60, 80, and 100%), giving us a realistic view of color accuracy.

The 50L7300U’s picture modes produce different results in the color gamut test. The first chart was generated in the Standard mode at stock settings.

This is a perfect example of why we measure additional color saturation levels. Red, green, blue, and yellow at 100 percent saturation are pretty close to their targets, while cyan and magenta are fairly wide of the mark. The lower saturations are quite a bit off, with errors ranging from 11 to 19 Delta E. The inaccuracy is compounded by super-high luminance values. Some colors are over 100-percent too bright. Visually, that results in an unnaturally-intense, cartoon-like image. A lot of the color detail is crushed as well, which removes texture and depth from the picture.

Although the 65L9300U has a CMS, we measured better chroma results without it.

This is a more respectable result. Our only concerns are the slightly low luminance values for red and blue, which can be corrected in the CMS (though the controls only affect the 100-percent saturation level). Lower levels are left unchanged. So, there is no real benefit to making that adjustment. The overall error when using the CMS is actually a bit higher.

Let’s see how the 65L9300U stacks up to our other HDTVs and monitors.

At 1.27 Delta E, Toshiba's Ultra HD screen ranks among the best. The test is particularly difficult because it takes the average of 32 unique measurements. Any value under three means the error is invisible. It follows, then, that all of the screens in our sample group pass. While we're glad the 65L9300U includes a CMS, it really isn't needed.

  • Argh. Why do people still make TVs with rear-exit connectors? That was the #1 hardest to find criteria last time we got a new one.

  • Toshiba still holding onto the 3D in their TV's. I got caught up in the hype and bought me a 3D TV two years ago and honestly I have only used it maybe 4 or 5 times if that. It's something now that I look back on I could have really done without and saved money on a regular HDTV, but live and learn. a cheaper non 3D version of this would be nice. I, like most people can do without the 3D function on a TV, esp if it will reduce the cost on the TV itself. It is nice to finally see a 4k TV come with HDMI 2.0 support, something that 1080p TV's don't need but 4k do in order to take full advantage of it by allowing 60fps.

  • Untill we get 4K contenent or GPUs can manage 4K resolutions in AAA titles with highest settings possible, 4K makes as much sense as a fast car in a 50 Km/h town.On the 3D matter, it does look cool on a projector if you get a 120+ inch screen, but in tvs, it looks like a gimick to me.Now... The HDMI improvment is something I want. Ive been wanting Full HD 60Hz 3D for a long time, and it seems 3D has been so unpopular that it didnt even make sense to invest in improving bandwidth.

  • You can do 1080p120 (equivalent to 60Hz 3d 1080p) over HDMI 1.4a easily... same bandwidth as 1440p60.

  • 4K TVs are bought by the same people who buy $100 Monster hdmi cables because "they give a better picture".

  • Actually, 4K TVs can bring a better picture. Especially if one has 4K content, or is viewing pictures or text.

    Monster cables are definitely crap though.

    Argh. Why don't people use a cheap angled adapter.

  • Why doesn't anybody add DisplayPort to TVs?

  • Which is extra failure points, and can block other connectors.

  • $1500 - $2000 would be the "sweet spot" price point for this TV.Still I'm glad to see this at $3500 is not too "exotic".... LOLSo it could reach the $2000 "sweet spot" within a year or so... Good review by the way.

  • 51 ms of input lag is too much lag for any gaming, fyi abesofmaine has a few 55 inch 4k monitors by sony samsung and lg closer to $2000 frees shipping and no tax. the 65 inchers are still $3k and up.

  • I have a Toshiba set in the bedroom and it's only OK overall.Of course, part of that is the 65 inch Panasonic plasma in the living room. Only 1080p, but incredible picture in every aspect. I spent about as much on it last year as this Toshiba costs now at MSRP. Don't regret a penny.Given the dearth of 4K content, I'll stick with this plasma beast for a while. May be the last year we see plasma, so I'm about to see if the 100,000 hour rating on the panel is for real.And, I'd put my calibrated Panasonic against any set, including 4K machines, with 1080p content. And I'd win. Sadly, resolution and 'smart' features are the focus of these early 4K sets and as picture comes behind.That said...it's 4K! This will be neat...in 2-3 years.

  • This TV is similar to the Panasonic TC-L65WT600. According to THX, you have to sit 6.5 feet away from this TV, at most.

  • I want 4k 120hz min, with 3d, and no need for WiFi or internet in it and at 50". For no more than $1k. That's when ill buy. No not some almost. But true 4k. It would be nice though if I could add a blutooth dongle for video receiving from my PC.

    Do you sit under 4' away from your TV or something?

  • I've had very good luck with Toshiba TVs in the past 6-7 years, purchasing for myself and recommending to friends and family. It is nice to see their picture quality is still top tier.

  • So uh, why does Dell charge the same for their 32" US again? This has twice the real estate, and similar (if not better) performance, but costs exactly the same.Anyone?

    I guess the ultimate in picture quality right now is 4k at 60Hz. The Dell can connect to your computer via Display Port 1.2 to achieve this, but this TV cannot. It's rather a future proof concept that will accept an HDMI 2.0 capable 4k set-top player.

    no. My point is I don't need or want all that extra stuff. When I can add my own WiFi and internet for far far less than they offer. I want great screen with great refresh and 3d ability. Everything else is meh. I don't want some android chrome or apple in my tv either. If they want to truly go somewhere with tvs, let us wirelessly sync into the tv with what we want. My PC is within 30ft of my tv soo...
