LCD Monitor success!

[Franko]

I've tried a number of different LCD monitors or LCD TVs from various manufacturers in the past couple of years but always end up going back to my CRT monitors as I can't find one that doesn't suffer from motion blur when scrolling...

Even ones that claim to be 2ms response time and are supposedly not to suffer from motion blur still do. Anybody found one that does actually work without motion blur and if so what's the make/model number...

@Franko

Try changing your perception; call it "movement anti-aliasing" rather than "motion blur" and consider it a feature

You do realise what you have just done don't you Karlos...

Some advertising executive from Sony, Samsung or whichever is going to spot that comment and use it on the box to sell their flawed products under the guise of it being an extra feature...

Gawd, I'll never see an LCD monitor now without motion blur... :cry:

My Iiyama ProLite has a 2ms response time and I can't say I've noticed it being particularly blurry when there's movement.

'Particularly blurry' is a bit like saying, ok it's a 100 watt bulb but it really only gives off 60 watts, doesn't cut it with me Im afraid...

I have an Envision EN-LM500 Professional Series flat-panel monitor attached to my Amiga 3000T. My graphics board is a GVP Spectrum and I am using the P96 driver. My settings are 640 X 400 res, 16-bit color, 60 Hertz. There is no motion blur at all. Great picture and color. The only negative thing I can say is that the picture is not as crisp and clear as a CRT monitor.
 
Make sure that you are not trying to push the monitor beyond what it can handle.  You have to remember that these old Amiga computers are not modern PCs or Macs.  So, I have found that it is best to treat them as vintage computers.  It is best to stick with the lower screen resolutions.  Never go beyond 1024 X 768, you WILL have problems if you do.  At least this has been my experiance.

I've never tried that model, need to check out the specs for it first. I never usually use a screenmode of more than 640X512 (mostly 640x256), I'll dig around and see what I can find out about, but I'd be very surprised if it has no motion blur at all, as even Panasonic with their 600Mhz TV's have had to admit that despite the latest engine they use, motion blur has not been completely eliminated yet...

What about the stationary blur you get on CRTs the entire time you use them? The focussing, mask and fundamentally analogue nature are physically not capable of giving a crisp, neat, square pixel at any resolution. There's always some distortion and diffusion.

At least on LCD displays, native resolution is always pixel perfect.

Stationary blur

As for the focussing if your capable and know what your doing you can easily adjust the flyback to produce a perfect clear sharp picture. Also if your willing and capable to take the time the coil on the neck of tube can be adjusted to get near perfect convergance for all three colour guns. Any convergance problems still left over can be eliminated with the use of small thin magnetic or metallic  strips you carefully place at strategic points on the actual tube itself even under the coil.

I have done this to all the monitors (and TVs)  I own and the picture quality for native resolutions is far superior to any LCD monitor I have tested and of course is free from motion blur not to mention far better contrast & brightness ratios...

My brother in law who is a fully qualified TV engineer has even borrowed some of my monitors on occasion to show his fellow engineers who have all been most surprised and even amazed at the picture quality I have achieved using the above methods. As he and his fellow engineers say "most folk wouldn't know what a good picture looked like if it came up and slapped them on the face" and they speak from years of experience in this field...

[Franko]

Wrong, it is never perfect and that is the point. A pixel that exists conceptually as a discrete rectangular area within your framebuffer is mapped to a diffuse point on a screen by an analogue system that is highly susceptible to electric and magnetic fields. Everything about it, from it's position, shape, brightness and even it's colour are affected by multiple, nonlinear effects. You will never get the same combination of these effects from one day to the next. Your CRT display literally is never the same twice.

Simple answer to that Cobblers...

Contrast this scenario to LCD, where you have well-defined rectangular (usually square) pixels that aren't susceptible to any such effects.

You forgot to mention these lovely square or rectangular pixels have a tendancy to end up stuck or dead...

Basically, what you have described is a trial and error manipulation of the fields around your monitor. If you move your monitor, the necessary placements to counter things like the prevailing magnetic field direction all change too.

I refer you to my first answer given in this post...

[Franko]

I have to admit that CRTs beat LCDs almost every time in terms of picture quality.  

I love the low power consumption, wide screen aspect ratio and thin-ness of LCD monitors.  

But CRTs can handle tons of scan rates and resolutions and they always look great.  You can also view them from any angle without changes in brightness.

The only thing that really sucks about CRTs is how heavy and large they are.

I agree with you 100% on that, apart from the motion blur the viewing angles on this crappy technology is awful...

[Franko]

Don't get me wrong, I prefer many things about a CRT picture, but one has to be realistic.

I am being realistic and the view of TV's engineers I know back me up on this. Most of them still prefer CRT TVs in their homes as they cannot stand the motion blur, ridiculous viewing angles and lack of decent contrast/brightness ratios. I am in full agreement with them.

Nope, it was spot on. You can refuse it all you like, but a digitally driven LCD display is as close to an exact representation of what is in the display memory as you are ever going to get. A CRT can't even come close. Project a perfect grid of lines on your CRT and see how uniform they aren't on close inspection. The whole picture is distorted, which is why any decent CRT has so many geometry adjustment settings.

I don't just use my monitors for computers I also use them for TV/DVD viewing and the SNES and thanks to a box of tricks I built can do so quite easily even on my MicroVitic Multi sync which has separate H & V syncs which few if any TV or DVD boxes give out, and anyone who has viewed them side by side with an LCD, have agreed the CRT picture quality is superior...

Whereas CRTs suffer no degradation issues :lol:

Of course they do over time but this can easily be repaired and if you keep the brightness and contrast at reasonable levels you will get many years of good use from a CRT without the picture becoming soft also they don't suffer from what most LCDs do, that is an uneven backlight...

[Franko]

Hm, have you also tried LED displays?
I got a Samsung Syncmaster BX2235 and I have little to complain about. Granted, it does not have the absolute blackness of the OLED display of my GP2X Wiz, but the picture is awesome, and I haven't noticed any motion blur (unlike on my Samsung LCD tv).

But then again, I haven't used a scandoubler on it and maybe that's exactly what's to blame, the internal scandoubler of LCD tvs being of poor quality.

I've checked out a few Samsung models, though I can't say I've checked that particular model. Trouble is no matter what the manufactures claim on the box or in their ads if you question them on their technical helplines or via email and push them hard enough they will all admit that even the latest TVs/Monitors have a degree of motion blur, it's just that most folk don't notice it except for fussy buggers like me...
