This is why I'm thinking that perhaps it could be a HDMI cable that's the issue. Haven't had time to test different configurations yet.

I've also tried changing color space options in the Oppo and turning Deep color off etc. No difference.

Thanks for all the suggestions guys, will definitely know what to look for when looking for a calibrator over here in Australia.

just guessing here, but it might be the Oppo having an issue with streaming DL content... especially mkv files etc are open source container that could contain anything including newer (or non-standard) versions of codecs... if the Oppo does not fully support the codec (used in the media file) or it's a non-standard version of the codec, all kinds of funky stuff can happen when the Oppo decodes the content and then streams it...

I've had my media players have problems with some mkv files until updates came out for the media player that fixed it...

OTA through my Tivo Roamio. It's one of the few shows I've had issues with. I guess I should be glad I won't have to worry much about it after next week's episode biggrin.gif

When I switch my TV on and look closely, I notice in the centre of the screen there are quite a few black pixels which fire up seconds later, like they are lazy or something. Is this a sign of a fault developing or normal behaviour?

Revolution's dark scenes usually looks like crap on my TV as well, from Direct TV.

hi guys,

I've been doing a lot of PS4 gaming on my 55VT60. I'm having trouble with the picture settings. I'm using the default THX cinema mode for just about everything, as I've got all my devices running through a receiver.

My problem is that the blacks are too black, and I either can't see in dark scenes, or loose picture details I normally have on my LCD, or my whites are too white, so when playing Battlefield 4 for example, the 'snow blown' effect on one of the maps makes the scene invisible.

I love the THX cinema mode for blu ray content, but its not ideal for gaming. Has anyone got any idea what I should be adjusting to solve this problem? I'm not that knowledgeable with this stuff - just need to be pointed in the right direction.

It sounds like a color space problem. That will crush your blacks and whites if both units aren't set the same. Try going into the PS4's settings and look for something like standard or normal picture instead of extended or wide. Of course the tv has this adjustment in the settings, but if you adjust it there your other sources may be off.

Why not just try Game mode?

Some games have brightness option in the video settings. I have to set this to as bright as possible in black ops II to see people hiding in the shadows.

I've got that set to auto so when a game is on it turns on, and when it's a blu ray it turns off, but in terms of these issues it doesn't seem to make a difference - it's still on THX Cinema mode but with Game turned on.

Yeah I've tried this on some games and it works, like infamous second son which looks amazing, battlefield and assassins creed iv are perhaps the worst for it though, for example bright reflections are blindingly white and loose detail, and blacks are exceedingly deep loosing visibility on dark scenes/levels.

I'm sure it's just a brightness or perhaps gamma setting, but I'm wary of messing with the THX defaults. I was thinking perhaps just switching to normal 'cinema' for games, and adjusting settings - which from I can tell won't affect THX mode if I adjust the gamma etc in a different setting.

I just need to figure out what to adjust.

I could be wrong but I don't think the TV changes to Game mode automatically.

What are the primary colours?

 

I wonder if someone may help me in this respect.

I calibrated my 55VT60 for REC.709 and Pictures just look fine.

 

But I want to use it as a screen to do photo retouching as well.

So I guess I'm better off using a different setup to make use of a wider gamut and profiling the screen within the Computer's display options instead.

 

Goal is not a proper reproduction of video material but instead the widest possible gamut the TV can produce.

Is there a way to find the best contrast and primaries settings?

I guess I should start from the factory presets and need to set color space to 'native'.

 

Any ideas?

 

Thanks!

looks like a xvYCC issue.

Your PS4 maybe generates 0..255 values (and your game can only do that?)

Your Reciever ignores this an sends it's interpretation of 16..235 to your TV (seems to be quite common)

Does a direct connection help?

I'm not an expert. Just my idea

you say you "calibrated the VT60" yet you ask what the primaries are ?

how exactly did u calibrate the screen ?!? smile.gif

primaries are R|G|B... secondaries are Y|C|M...

don't use this screen for photo retouching...

I used HCFR and an i1D2.

Some iterations:

contrast

gamma

primaries

greyscales (eyeballed)

gamma again

primaries again

secondaries

done

 

Why would I not use the screen for photo processing?

 

I just read your LS LUT calibration post. - Wow, I do not expect to get any near that professional level.

Maybe sometime, when the display aged enough, I will invest in a professional cal.

But for the moment I'm in search of a 80/20 solution.

the Plasma is unstable and then u certainly don't want to display a PC desktop on it because of IR... maybe extended desktop, not sure... why would u wanna use the VT60 for photo retouching ? I'd use ur desktop LCD (connected via DVI or DisplayPort) and get that as close as possible to sRGB / Adobe RGB etc... if u decide to use the VT60 via extended desktop then make sure all ICC profiles are disabled and none are still loaded in the OS, otherwise ur "calibrated" VT60 will not show accurate colors coming from the graphics card...

regarding your cal: the i1D2 is an outdated, not so great in the first place colorimeter... it will have drifted substantially by now, ergo there's a great chance it is useless for color accurate reads... even with a spectro offset (--> reference meter profile) this meter is not so great (repeatability, speed etc)...

an i1D3 with a used i1Pro rev D (off eBay) is a great budget starter kit...

Hi Mike. FYI I use my VT60 as a computer monitor everyday, in fact I'm using it right now. Just a few cautions to avoid IR and I have no problems.
1. Use a wallpaper changer.
2. Get rid of desktop icons.
3. Autohide taskbar.
4. Maximize all screens to get rid of the top bar.
5. Use the shutdown function to shut off the computer's video output after a few minutes of non use.

As for photos, I do my photo retouching also- that's where I get the photos for the wallpaper changer. Since pretty much the only place I view photos is on the VT60,
I would want to retouch them to look their best on it, right?

Does this happen on all sources? Try a test pattern on a Blu-ray player if you can.

I've tried everything from re running dnice slides to the pixel wipe for weeks, and have lived on my mac book pro instead of the vt 60 to let the pixel wipe run continuously. This set is 5 months old, and I did the slides for the 1st 100 hours, and no static logos for the next 100. I used the airplay from my mac to apple tv, and unfortunately didn't make the airplay take up the entire screen on the tv. There is a burn in from the air play that Simply won't go away. Unless someone knows something I don't, Im going to have to use my replacement value warranty from best buy, and get rid of this, and find a set that isn't susceptible to burn in. I never had this problem with a previous lg plasma who's black level's were gray at best. I guess it's time for a 4k led, The burn in is only noticeable when the screen is one uniform color, but this is not ok, and as far as I'm concerned the set is as good as dead.

I don't believe you have burn in. It is very difficult to get true burn in. Your problem should be easily fixed. Basically the rectangle your Apple TV created in the center of your tv; those phosphors are aged much longer than the surrounding. All running slides will do is age all pixels evenly, leaving your problem. What you need to do is make a 1080p image with a black rectangle the same size as the one that shows on your tv. And have white surrounding it. Then run that through hdmi from laptop or sd card for however long you used the Apple TV.

Theoretically you're right, but it's not practical. Vivid full screen movies like Pixar's films, set to repeat, have been effective because the pixel activity is random. Many have reported that the pixel flipper in Disney's WoW disk is effective too.

Thanks, that's a great idea, but I think I will have to do the reverse since the area surrounding the burn is lighter than the rectangle in the center of the tv. I would think I should make a white rectangle the size of the apple tv burn in, and the surrounding area black unless i'm missing something. A black rectangle the over the apple tv burn will just make the burn darker, and the surrounding area even lighter.

A black rectangle the over the apple tv burn will just make the burn darker, and the surrounding area even lighter.
Theoretically the problem with that method is that you have to get it perfect or you could wind up with a rectangle with lines as wide as any error in your calculations. The results might be worse than what you have now since you can't see the problem unless you use a monochrome screen.

Best wishes. smile.gif

I ordered disney wow from amazon yesterday. Will try that first. Thanks

here's what i'm thinking. I can display an all black slide that fills 100% of the screen, and airplay over that a white slide that will perfectly fill the affected area. I don't think there's a gap in my logic, but let me know if I'm missing something.

I would recommend taking the advice of a long time forum member - HTWAITS - who has a lot of knowledge to offer regarding plasma tech and run the Disney WOW disk before trying the technique above which in my opinion won't work as well as the WOW disk if it works at all - plus the chance of the error mentioned above. Meant to be nice when I say this - don't seek advice on the forum and then ignore it without trying a technique that has a history being effective in solving your type of problem first. Your logic isn't unique. Good luck.

I hope it works for you. It seems to me that time is on your side since you're not seeing the problem with normal material. Also, nothing you've reported indicates burn-in but it does indicate image retention that's going to take longer than usual to go away. smile.gif

I don't know how you will get a perfect match. confused.gif
