Sounds like the same thing to me, and if your new set doesn't have the same issue, I will have to look at it in a few months if the increased contrast doesn't reduce or remove it.

 

 

If I was you I would change it now, John Lewis can get funny after the first month.

Sounds like they'll all be the same, or worse. This is the only issue I have, and it's relatively minor. The hassle I would have while working away would drive me crazy, and worse, drive my wife crazy, so it'll have to wait. The warranty is for 5 years, not 1 month, so JL will have to deal with it if it becomes too much of an issue.

RE: Week old 50GT50 Buzzing..!

Thanks BBB.

You're watching using the Cinema picture preset, right? Of course there's no colour temperature control on the THX preset. To my eyes, colours on the Normal and Cinema presets look off, whichever colour temperature I select. Have you tried the THX preset? I appreciate that you're being cautious while the set is new. One positive I can report is that I haven't seen a suggestion of image retention, let alone screen burn.

Sounds like the buzzing on my set is louder than yours, then.

Based on what I've read, I'm guessing all ST, GT and VT50s have DSE, which perhaps varies in intensity from set to set.

RE: Week old 50GT50 Buzzing..!

Yes, watching in CINEMA, I did click on the THX CINEMA and realised that I couldn't change the Colour in the THX preset. 

I'm at the point when I don't want to get too stressed out about the GT, I've only noticed it during football, so it's not a massive issue.

I'm starting to think that my old Kuro was the better tv, but the blacks, internet features, 3D, and brand new 5 year warranty still make me feel like it was the right decision to buy it. I do have slight motion issues too, and the Kuro was definitely better at that.

I just can't understand why a 5 year old tv can beat a brand new tv in so many ways, but what's the alternative?

Can you film what you are seeing with DSE and stick it on YouTube and link it here?

There isn't one at present. Maybe OLED will finally be problem free. I'm guessing that, as prices drop, manufacturing processes will be compromised by a need to reduce costs, leading to problems with that tech, too. Five years from now we could both be posting about OLED "panel fringing" or some other yet to be named issue. 

If I can't avoid DSE with the GT50, perhaps I can get a set that buzzes less.

It wouldn't be worth it with my low resolution HTC Wildfire. DSE on my GT50 looks a lot like this:

That said, this video still doesn't show the problem that clearly...

Have you accessed PROFESSIONAL 1 and PROFESSIONAL 2 picture modes yet? You can really go to town with colours etc there.

I saw a line going down the screen to the right, was that it?

True, but the Professional modes have a luminance cap and halve the MLL (those blacks don't seem quite so inky). That's why some people went for the ST50, since dynamic contrast is greatest on the True Cinema mode, which also has 2 point white and colour balance controls.

I need the Freesat tuner and preferred the look of the GT, which is why I went for the TV I bought. Guess I could have bought an external Freesat tuner, but that would mean further expense and another box under the TV. Besides, images are reportedly less accurate on the ST50, so professional calibration would have been a must for me.

Thanks Civilian.

What you're seeing isn't DSE. It's a limitation of standard definition broadcasts where pictures are less stable toward the edges. In other words, this isn't something you need to worry about, as it's not a problem with the TV.

I'd also recommend turing overscan off with HD material, as you'll get a better picture with 1:1 pixel mapping.

Yep, got it, I had that on my first one, just get it replaced.  Second and third one were fine.

I'm still willing to let the TV bed in for a while to see if things improve. I'll call John Lewis tomorrow and explain the situation. As long as they're happy to offer a replacement in a few weeks if things don't improve, I'll consider that perfectly reasonable.

I'll probably do the same, but it's going to be so awkward with me working away.
