I have a 24inch Full HD computer monitor. The Full HD is great as I download and watch all my movies, TV shows, music DVD's etc.

We have an old 32 inch HD TV (not Full HD) and when I connected it to the PC it would lag (mouse pointer would be on a delay).

I read that there's some sort of letter code that shows the level of lag when used as a PC monitor, so you can see how fast it will operate as a monitor - Letters then numbers showing the speed, lowest is the fastest.

Any knowledge on that?

Some people also say that TV's make lousy PC monitors compared to actual monitors.

With 32inch Full HD TV's being so cheap, 8-10k baht, it would be a good upgrade from my 24in Full HD monitor.

But how to know if it will work smoothly and instantly?

(No I don't really want to hike my PC into a TV store and test it in store. )

PC Connected via DVI.

btw.

You can buy 27" full HD IPS monitors for 8-9k baht (AOC brand)

Thinner, more elegant.

Yeah, I saw them on invadeit.com

To be honest, I'd rather a 32in in the long run (more moives/TV shoes, less PC work).

To answer my own question a little bit, the term is 'input lag'.

I believe it's quite untechnical, and it's just recommended that your google the TV model number with 'input lag' written after it.

Was hoping there would be a more technically advanced method.

I would also worry about panel uniformity. Suspect there might be other areas of concern as well.

I particularly liked the article describing the issue from this website:

TV Input Lag Test Database

What Is Input Lag?

This refers to the delay from the moment a display receives a signal from a game controller (for example, by moving the analog stick or pressing a button) to the results manifesting on screen. As modern flat-panel televisions come with more and more features included (motion-compensated frame interpolation, backlight dimming, 3D capabilities, smart functionalities, etc.), more time is required to perform complex video processing, unfortunately contributing to higher input lag.

From our experience, input lag is never made known by TV makers, who instead prefer to advertise a figure called “response time” which measures the time taken for a pixel to switch from either black to white or grey to grey (depending on which is more flattering). As a result, almost all input lag data available on the internet comes from end users rather than manufacturers.

^ I'm also looking at TV's online from places like itcity, powerbuy, homepro, all the TV's that are sub 10k baht are only HD (1366 x 768) not Full HD (1920 x 1080)

Kind of surprising, and certainly rules out one of them for use as Full HD monitor.

Perhaps it's just the ones I looked at, and Full HD ones are also in that price bracket.

If you choose PC mode or set tv to 1:1 pixel mode (just scan, exact scan etc, if it supports) there should be less post processing and less lag. However, expect atleast 40-60 ms lag.

I don't know about sitting a couple of feet away from a 32" TV. I would rather have a decent real 27" monitor. I see them on Lazada for under 8K baht.

I was in the same boat last year when I wanted to get a new 'large' LCD monitor for my computer. So I did a little research and it turns out most do not work well, but some do. Trying to find those that do is not simple as the manufacturers rarely state the models that will. I suppose in part to protect their real monitor sales.

In the end I just bought a real computer monitor. In my case I was looking for a 4K monitor, of which they are few, and I was not prepared to spend 100,000 baht plus for one. I ended up buying a new 28" Samsung model that was a computer monitor and 4K and was capable of operating at 60Hz via a DisplayPort connection. Less than 20,000 baht.

I have been using it now for about 6 months, and I will never go back to a lower resolution display for my desktop. The huge screen real estate is truely wonderful. Great for editing photos and videos as well. Games at 4K resolutions are something to behold.

My next display will be 32" or larger. Maybe next year.

You should get it calibrated if you're editing photos / videos.

I bought spyder4pro for $150 from ebay and it helps even with TN panels.
