LED vs Plasma

Maverick Jester - I've seen a lot of videos for Samsung ones showing this menu: http://puu.sh/2rQzz

If the blur looks "normal" and so many people were used to it before, what's the point of CMP and such tech?

I understand it is to counter-act display motion blur. But the problem is manufacturers taking a theory and over expanding on it for no real reason except as a marketing gimmick, IMO.
 
PostmanPot - Precisely. That's why I was so keen on getting a plasma. It's just unfortunate that I will be using it as a PC monitor, which means increased chance of IR, and perhaps even burn-in from a vast number of things - desktop icons, Windows taskbar, Chrome, game HUDs, etc.

Also, the reflections are worrying. I watched a video recently where someone had a window facing the screen and during the day it glared off the screen as if the latter was a mirror.

This was why I earlier asked what your ambient lighting conditions within the room the display would be located in would be. :)

Bl1zz4rd- the problems you will face in getting a plasma for PC work would be the ones you have mentioned (higher risk of image retention and burn in), as well as a rather poor looking graphical presentation, since the HDR plasma's are not natively HD and as such, your pixel mapping from your PC will be way off.

This is why I recommended an LED- you have a better chance of finding a Full HD LED display for the price of an HDR plasma. For PC use, you will need subpixel rendering and a 1:1 pixel mapping for clear text.

The problem is that LED-LCDs are about 90%+ as glossy as plasma these days.

Picture the glossy screen factor as per your laptop thread, LED-LCDs are like that now. Gone are matte finishes. In the name of competition, and quest to be the brightest on the showroom floor, if you know what I mean.

But yes, if you are using it as a PC monitor to do work on, I would not go with 1024x768.

Image burn is a non issue, plenty use their plasmas as PC screens. It seems you may need to up your budget to R9,000 - 51" FHD plasma territory.
 
Roman4604 - There are a lot more types than I was originally aware of.

Maverick Jester - The thing is... surely most rooms have windows and some sort of artificial light source. Is the solution to plasma to install and draw blinds and turn off all lights while watching the TV, thereby completely darkening the room, even during daytime? Seems a bit crazy to me.

Just so I can understand, what will the picture look like if I;

1. Output a resolution of 1024x768 from my GPU to a plasma with that resolution?
2. Output a resolution of 1920x1080 to the same plasma?

+1 if plasma is the preferred choice.

See my post about LED-LCDs with glossy fronts. Curtains/blinds are a must have, regardless of the tech, especially if you plan on doing a lot of viewing in the day. I'd imagine though, most people do their viewing at night.

Just so I can understand, what will the picture look like if I;

1. Less real estate, large Start bar/icons/text etc.
2. Plasma will down scale to 1024x768, IIRC you will get more real estate, but it won't be sharp. Think a really bad case of text needing Cleartype enabled/configured, but you can't.

Does it even make sense to have 120Hz and 240Hz refresh rates?
Click to expand...
As mention above it depends on what the vendor designed the monitor to do during those higher Hz. Interpolation is not necessary off a progressive 60Hz source, but the image blanking is helpful in smoothing perceived motion.

The main motion issue with lower end Plasmas is judder. Pan the screen around very quickly and you'll probably perceive some choppiness in screen updates (content/model dependant). Its because the pixels are so highly responsive and introduce no blur. But if the frame rate is too low for the motion, it will looks unrealistic since there is no blur or frame blanking mechanism to compensate.

Burn-in is rare these days, but you could get some temporary IR especially since the protection function (pixel shifter/orbiter) will be disabled in 1:1 pixel mode.

Another issue you may hit with PC usage is ABL (Auto Brightness Limiter). To maintain energy compliance, many Plasmas will dull the brightness of whites if too much of the screen is composed of whites/brights.

Not completely, but ensuring that direct (sun)light does not shine onto the screen, it should not be an issue. As PostmanPot pointed out (LOL), reflectivity is similar across the spectrum (LCD-LED-Plasma). But for higher ambient light, LED will be better than plasma due to their natural higher brightness levels.

With 1:1 pixel mapping set on your GPU, clear but still very strange. Such a low resolution on a large monitor is ultimately wasted.

2. Output a resolution of 1920x1080 to the same plasma?

[-]Well, for one, you would lose quite a bit of your screen vertically (displaying a 16:9 image on a 4:3 display) so it would be smaller[/-] ignore my idiocy there. Of course the display will downconvert the resolution to fit.

You would also lose detail the greater the overscan percentage is (this is an example).

I see. But is going above the 60Hz source not a bit overkill to combat judder? Or do manufacturers need to take into account display motion blur and increase the refresh rate? Just trying to wrap my head around why they double and quadruple the refresh rate.

Agreed, another problem is that 1024x768 would appear stretched due to the rectangular pixels.

If budget is R7,000, and PC work is important, then FHD LCD is a must.

I would just go with 46" Samsung 5 Series LED-LCD, overall very good PQ I've found and decent black levels (S-PVA). Do check the LGs though, you might like the colours IPS gives (poorer black levels, but better colours, generally).

OP, also avoid testing in bright conditions.

Probably for most this is going to (financial) extremes, but if you want the absolute best (large screen) motion, then a high CMR LED (with interpolation turned off) or FFD Plasma is what you want.
 
Holy hell in a hand basket.. PP is recommending a LED/LCD screen?!?!?!?! :wtf:

:p
