OT: TV as monitor
So, I'm in the market for a new monitor. I don't do much video or image editing.

I'm thinking of getting a TV and using it as a monitor. I like the idea because I feel it is a better bang for the buck given the connectivity (I also don't own a TV). The quality of TVs now seem to be adequate for what I do (which is mostly work inside Reason). I've been pretty satisfied hooking up to friends' TVs when collaborating.

The one I am looking at is a 32" Samsung Class LED 1080p 60 Hz HDTV.
I'm familiar with Samsung TVs and feel I would be satisfied.

Thoughts? Anybody else doing this?

Don't beat me up =)

I've used my Samsung 40" led tv as a monitor for a while. It rocked. But it was just too big lol.

LOL nice. I'm thinking 32" will do just fine. Most of the monitors in the same price range are 27"

just remember to splash some colour around and animations etc or the tv itself to stop the dreaded pixel burn in ;).
other than that hd tvs are what i got set up to mine superb picture and crispness.
i use the hd rather than the computer input port, seems much better.

LCD or LED tvs don't get any pixel burn. At least not permanently. LCDs are also what almost all monitors use anyway, so they're practically the same.

my lcd does show shadow after leaving on with static picture for hours on end . it does clear after running colours or animations for a few minutes.
but my big 42 inch i connect to when im messing around in other room is a plasma screen they keep burn in and its a lot harder to rid .

heres some handy info for you to digest :).

What is Image Sticking in LCD Display Panels?

Many are aware that if you leave a static image for a prolonged period of time on a plasma TV, you risk phosphor burn-in. The result is that once you remove the static image, you would still be able to see a faint outlineor ghostingof the original image, even when you change the picture content.
CCFL and LED LCD TVs do not suffer from burn-in, yet they may still suffer from image retention when a static or semi-static image is displayed on the screen for too long. The intensity of image retention depends on various factors, not just the duration the image remains on the screen. Issues such as image makeup, operating temperature, and the LCD panel brand itself, should also be factored in.
Image retention in LCD panels is often referred to in the LCD industry as 'image sticking'. As with burn-in, image retention is a phenomenon where a faint outline of a previously displayed fixed or semi-fixed image remains visible on the screen even when the image is changed.
Note that though burn-in in plasma TVs and image sticking in LCD displays both result in image retention or ghosting, yet burn-in and image sticking are two different phenomena.

What Causes Image Retention in LCD Displays?

Image sticking is an intrinsic behavior of TFT LCD panels. It is the result of their susceptibility to polarization of the liquid crystals inside the LCD display panel when a static image remains displayed on the screen for too long.
This results in parasitic charge (polarization) build-upwithin individual pixels and sub-pixels at the liquid crystal level in the LCD panel; it affects the display optical properties as it prevents the crystals from returning fully to their normal 'relaxed' state upon deactivation.
More specifically, the result is a 'retained pixel charge'. This can affect the crystal alignment at the bottom or top of a liquid crystal cell, or even migration to the edges of a cell, depending on the resultant polarity of the parasitic charge buildup. These conditions may cause image sticking over an entire area of the screen, and in particular over those boundaries where there are distinct color changes.

The severity of the resultant image retention would as pointed out above, vary among different brands, and depends on several factors including:

- An operating temperature that is out of the recommended operating temperature range,
- time the static image remained onthe longer the static image is on the worst the image sticking effect, and
- image build up—including the image pattern itself as well as image contrast and brightness levels.
Is Image-Retention in LCDs Reversible?

Unlike permanent burn-in in phosphor-based displays, which is the result of a premature and permanent aging of the phosphors of individual pixels, and thus, is irreversible, image sticking in LCD panels can often be reversed to a point of total invisibility.
However, the extent to which image retention can be reversed depends on the severity of the causes that led to image retention; top in the list is the environmental temperature at which image sticking took place.
A way to remove a retained retention on an LCD panel is to run an all-white screen saver for several hours. It would generally help to run this image sticking reversal operation at an elevated temperature of around 100 deg. Fahrenheit or 40 deg. Celsius. This should help speed up the reversal process.
Some manufactures recommend using an all-black or dark gray pattern screen saver instead of an all-white screen. Whichever method you choose, make sure the LCD TV or monitor energy savings settings will not turn the backlight off after some time of inactivity. Other manufacturers recommend turning off the LCD display for a longer period than the time it took for the static image to cause image retention.
While all three methods can help remove image sticking, our best advice is to follow the manufacturer's instructions when available.
Manufacturers' Warranties against Screen Burn-in and Image-Retention

Generally, manufactures do not warrant an LCD display device against the occurrence of image retention. Both burn-in in plasma displays and image retention in LCD panels are considered by display manufactures as phenomena that are inherent to the respective phosphor-based (CRT and Plasma TVs) and LCD display technologies. Furthermore, their occurrence is tied up to their end-use and as such, the possibility of an LCD display developing image retention is end-user dependent.
Avoiding Image-Retention: Simple ways you can take to protect your LCD display

The best way to avoid image sticking in the first place is to prevent the prolonged presentation of static images on the screen.
Try not to display the same static image on an LCD panel for more than 2 hours when working at normal ambient temperature. However, some manufactures recommend reducing this to as little as 30 minutes when working in an elevated temperature environment (above 95 deg. Fahrenheit or 35 deg. Celsius). Make use of a dynamically changing screen saver and adjust its settings accordingly.
In home entertainment applications, many do not realize that prolonged presentation of those vertical or horizontal gray or black bars, say when viewing 4:3 program content over a wide-screen LCD panel, is also a form of static image. These should be avoided by choosing an aspect ratio or zoom setting that expands the image to fill the whole screen area.
Similarly, avoid pausing a picture on your LCD TV screen for too long, nor allow station logos, program menus, etc., to remain still on the screen for an extended period. If for some reason, you need to pause a film or a show to do something else, it is better to turn off your LCD TV set. It is true that a few minutes in this state would not do any harm, but what if you forget about your TV after say having answered a phone call?
Finally, you should always power down the display panel during periods of extended inactivity.

Good info.

In any case, I am looking at LED LCDs TVs and I never have a static image on my screen. When my screen is on, I'm working (moving stuff around), or watching shows online. When not in use, it is off.

I'm not too worried about it. But I really appreciate the heads up =)

I think I've come to my senses and will be getting something smaller. Maybe 24"
The best resolution I can find in my price range is 1080p and at 32" that close to me isn't going to be as nice... In which case, monitors are cheap enough. Silly me.

You can set the resolution of your computer to 720p.
