    I am getting poor picture quality trying to watch football via Digital Cable with this television. Have tried loads of different settings with no success. In fact any sporting programmes with large expanses of grass i.e. football, horce racing, cricket seem out of focus with appalling colour fizzing. Generally the picture quality from cable via RGB Scart is excellant across all channels.

    My current settings are based on picture mode 3

    Contrast 48<br />Brightness 50<br />Colour 55<br />Tint +20<br />Sharpness -30

    I have tried all combinations of Scan Mode, with DNR on and off

    Can anyone out there offer any assistance please <img src="confused.gif" border="0">

    DNR should be off when viewing a digital source.

    My settings are generally lower than yours (same tv)

    Contrast: 30<br />Brightness: 40<br />Colour: 35<br />Sharpness: -45

    However, it is not the tv that is at fault. It is the amount of compression used by the broadcaster. Sometimes the grass looks like it is drawn by crayon. The effect is the same on my other 2 televisions (fed via RF).

    Doubledoom,

    Why should DNR be off for digital sources? Can you explain precisely the effects of Scan mode and DNR.

    Thanks,<br />\vs

    Corty, I've got the 36" version and NTL Dig cable. Sport generally is fine on mine - it was originally one of my concerns that football would be a problem 'cos of the reports I'd heard about 100hz. I don't have any problems with any sport I'm pleased to say.

    Are you getting it on all channels where sport is shown because what Doubledoom says is absolutely right - on Sunday I watched the Utd v Villa game at a mate's house on ITV pay per view via NTL Dig, he's got a 28" 50hz w/s set and the picture quality was appalling - it was like looking at blown up low res JPG's moving around on the screen. If it had beeen on my TV I dare say it wouldn't have been watchable. How they get away with broadcasting such crap is beyond me.

    Cheers<br />OG

    Digital noise reduction (DNR) is used when you have a poor quality transmission or recording. Very basically it softens the picture in an attempt to fool you into thinking it is not as bad.

    You should not use it on digital sources as it can make the picture the worse, not better. Digitally changing a digital transmission / recording can lead to a shimmering effect. It also tells you in the manual not to use DNR on digital sources.

    Scan modes are more discreet. Personally i find that the Natural scan mode gives a bit more motion blur than the 100hz setting. As for what it precisely does and how it does it, i am not sure at this stage.

    Thanks for the advice, I'll try lowering my settings a little to see if this helps. I feel comforted that the problem is not specific to my television.

    OG<br />The quality varies from station to station - sometimes its O.K. other times its appalling. I also watched the Villa v Man U game down the pub on Sky. The picture was great, just a shame I had to share it with a load of Villa fans (why weren't they at the game ??). Before you ask, NO I am not a Man United fan (Baggies boy !!), but I had difficulty suppressing a smile when they scored near the end.

    Thanks for the advice and information

    Hi all,<br />My 36&#8221; Tosh settings are.

    Contrast 45<br />Brightness 54<br />Colour 32<br />Tint 00 (This should not have any effect on pal transmissions)<br />Sharpness &#8211;30<br />Scan Mode 100Hz<br />DNR off

    As you know there are 3 default picture mode settings and picture mode M.<br />If you view the default picture mode 1,2 or 3 and then make any adjustments those adjustments are saved into the picture mode M settings.<br />I started in default picture mode 2 and then adjusted my settings as above.<br />I am led to believe that default picture mode 3 has &#8216;Horizontal Scan Velocity Modulation' turned off which some people think is a good thing to do? Personally I started in picture mode 2 then I made my adjustments as above<br />The thing to be aware of is that the 3 default picture modes may have certain unknown options enabled or disabled like the &#8216;Horizontal Scan Velocity Modulation' being disabled in picture mode 3.<br />See how it works for you and let me know.<br />Paul<br /> <img src="smile.gif" border="0">

    Wow, I checked my settings last night and they're much higher than Paul and Double's.

    Con=70<br />Bri=57<br />Col=64<br />Tin=00<br />Sha=-30<br />Scan=Natural<br />DNR=Auto

    If I change the colour to 32 it's almost B&W.

    I'm happy with the look of the picture at the moment so I'm waiting until my Video Essentials disk arrives before making any other changes.

    Looks like each TV must have different looks at different levels 'cos I assume if one of you guys put the colour up as high I as have it you'd be sitting in your lounge with your shades on.

    Cheers<br />OG

    When running the video essentials DVD did you have your DVD hooked up via componenet video leads or Scart. I ask because my DVD is via component and I find the colours slightly dampened in comparison to Scart connections.

    OG can you try this, set your TV to picture mode 2 then enter your settings as above, how does it look now?<br />Do you find you have to reduce your settings more in line with ours?<br />Paul

    One more question about Video Essential. The bargain from Australia seems very good. However, will the DVD be PAL or NTSC? And, more importantly, would that make a difference while setting up a set like the Tosh 32PZ18P?

    The VE Disk is NTSC only<br />However having setup the set in NTSC mode, standard PAL pictures have also improved.

    Amazing how much better a correectly setup set looks compared to the factory settings.

    The dynamic contrast is turned off in picture mode 3 and amending these settings (so that they take the M settings position) keeps it turned off.

    Going to pic mode 1 and mode 2 turns the dynamic contrast on and amending these keeps it turned on

    It has the effect of automatically increasing the contrast in dark scenes and decreasing it during light scenes.

    Problem is that you can often see the change happen and it is offputting.

    Corty - I've not had time to set up with VE yet - only received it earlier this week, but I do have it connected by component so I'll let you know.

    Paul - I tried my setting on Picture Mode 2 and it was dreadful. The now and next banner on NTL has white text on a translucent green background and the text was way to bright it was hardly readable.

    I played with the settings and had to bring the contrast down to below 50 but I didn't get the picture how I like it. I put my settings in on Pic Mode 3 and hey presto, it was back.

    Interestingly, I've been dying to have a go at the VE disk but haven't had time so I just stuck in Chapter 10 (can't remeber whether it was Contrast or Brightness test) but it has 2 blacky grey bars on screen where one should be invisible against the background but the other should remain in view and mine appeared perfect! I'll know better when I get the time to set it up properly with the VEdisk, but then there's nothing to say that that will produce the result that 'I' like!

    Cheers<br />OG

    I tried out pm3 and the picture seemed a little blurry to me, particularly text on screen. Maybe this is just with Sky Digital.<br />I went back to pm1 and con 51, bri 64, col 54, sharpness -40 and it seemed clearer again.<br />Anyone else tried picmode3 settings on sky digital?<br />P.S Seems a while back O.G since we started these Toshiba discussions!!

    Frightening how quickly time passes Pauleylad (god that makes me sound like and old fart).

    Wonder when we'll sit back and start enjoying the tele rather than tweaking it (probably when we start talking about the Plasma we're replacing it with - should be about the right price in a couple of years)!

    I use skyD on pic 3 amended settings.

    I have modified my settings slightly since earlier in the thread and they are now:

    Contrast 35<br />Brightness 42<br />Colour 33<br />Tint 0<br />Sharpness -45<br />scan natural<br />DNR off

    Picture is first rate via RGB scart, although i needed an improved scart lead to reduce shadowing that occured on the standard sky scart lead

    Thanks Double - think I'll keep mine based on PM3 settings.

    Played a little more with VE last night and ended up with Bri & Cont around late 50's. I'll post settings when I've gone thorugh it all properly although early signs are that my eye wants a bit more on the Bri & Cont front than VE suggests.

    Cheers<br />OG

    This set should look perfect out of the box. There are a few tweaks that can be made via the service and desinger menu to improve things further but you would only do these if you want absolute perfection.

    I guess you should arrange a visit by a service repairman.

    Ive just received my second Toshiba 32ZP18P, however it seems worse in some respects than the first.<br />Old problems that still exist:-<br />The vertical black bands being different sizes on left compared to right, also sometimes they are concave, and the screen being slightly clockwise (ie a full length banner at the bottom is higher by about half a cm on the left). Can these problems be fixed by an engineer?<br />New problems:-<br />The picture is more grainy than the last one, and there are slight red outlines round things when there is high contrast (eg a persons outline against a light sky)<br />Can anyone shed any light on these problems before I get an engineer out who may try and fob me off with technical explanations!<br />All replies greatly appreciated.<br />Cheers<br />Steve.

    Regarding my questions a couple of posts ago, why exactly are high contrast outlines slightly red and blurry? Is it a problem that can be fixed? Im scared to ask for a third tv!!

    Sounds like a fault. As i said earlier, this set should have a perfect picture out-of-the-box.
