Can 24 inch LCD TV display computer graphics as a 24 inch LCD monitor?

Forum Graphics & Displays : Graphics Cards Can 24 inch LCD TV display computer graphics as a 24 inch LCD monitor?

I am planning to buy this LCD TV which is 24 inches in size:

http://www.letsbuy.com/electronics [...] 11311.html

Now they do write under its tech-pecs, that it has a panel resolution of 1920x1080, but I am not sure whether I can
use my computer on this tv using VGA port at the same resolution. I know that the media from my set top box, ps3, etc will run at that resolution if given,
but will the computer run at that resolution on a TV which also works as a monitor?

Currently I am having an LG LCD Monitor which is also a TV(the other way round), I am having excellent resolution while working on my computer, but I don't think
it has the best picture when I plug in the TV cable or my PS3. I mean its good, but its an LCD monitor first and then a TV, while an LCD TV will be a TV first and then a monitor.

I want to get this doubt cleared about the working resolution on this 24 inch TV, if anyone has experienced or seen. Thanks in advance.

"when I plug in the TV cable or my PS3."

what cable would this be then??
if it is hdmi, there shouldn't be any difference between your current monitor and that new TV... And the ps3 connection shouldn't use the tv tuner part of the screen anyhow in either case, so it should not make any difference......

Its not about the cable, I want to know whether this TV supports 1920x1080 resolution while using PC or not. I know TV and PS3 are not going to be a problem, but while connecting it to PC, I have heard some support only 800x600, some 1280x1024 and these resolutions are going to look real bad on such a large screen. 1920x1080 looks best on my 22 inch LG Monitor which is also a tv. But this philips model is a tv which can also b used as a monitor which makes the difference. It has been prioritised to function as a TV than a computer monitor.

edit and 'prioritizing' doesn't really mean squat, if it has a tuner it can show tv signals and if there is a hdmi it can show whatever you plug into it etc, (though all the extra usability might be different like teletxt, electronic program guide etc on the tv part...)

Plug your computer into it via VGA or HDMI and it should work the same as a monitor with the same resolution.

If it doesn't matter, then I suppose the maximum working resolution on this monitor while using my computer with an HDMI cable, should be 1920x1080? Is that right? But the thing is my computer doesn't have an HDMI or DVI port, it has got the olden VGA port. So will it be possible to have that resolution through this port on this philips tv?

But then I also saw this FAQ :
http://www.p4c.philips.com/cgi-bin [...] &faqview=1

Scroll till the end of the page for resolutions.

Is it in general or specifically for the 24pfl5505?

Too confusing

Reply to wroxtar

I think that faq really is for the 24pfl5505, so maybe it does support it... and frankly those resolutions would make much more sense than the ones I quoted from the manual.

yep it's confusing, mixed info. Guess there is only one way to find out, go to a store that actually has one of these on display and plug one of their laptops into it

Reply to Kari

Right, that's the only option left I guess now. Thank you very much for your time and help Kari.

But do tell me, is it possible that a full HD TV can't output 1920x1080 resolution on a pc? Why would they make such a TV?

Reply to wroxtar

beats me :?

Reply to Kari

I have ordered this TV and am waiting for those people to ship, I'll let you know when I receive it. Thanks for all your help.

Reply to wroxtar

I guess I am quite a novice to understand that. If the tv is capable of displaying 1920x1080 for tv, why not for pc?

You buy a LCD that your gpu can power.
Interlace and Progressive<- that's why there's different resolutions for pc and hdtv.

u do know that hdtv broadcasting is done in both formats depending on channels and countries. And you can setup your pc to output in either one (at least my ati does). So your statement doesn't make any sense. :non:

Yes that's right, we can set it to 1080i or 1080p.

An LCD computer monitor is designed to be just that, a computer monitor. Computer monitors are non interlaced (progressive) displays. HDTV at its best resolution is interlaced. You would get a lot of motion artifacts. Some (a minority) HD broadcasts are at the lesser resolution of 720p (progressive, meaning no interlace).
But displaying the fast motion and high resolution of an HD movie or TV show could cause a great deal of blurring, which would be distracting to say the least.

Viewing distances are a important factor with LCDs. Your going to sit up close to it with a huge screen small resolution. Moving back its going to be better but you won't see much on the screen then due to everything in windows being small. then gaming. Not all gpus can run 1080p.

but TVs can handle them both just fine as should monitors that have built-in tuners.

edit wiki (yay) says this
http://en.wikipedia.org/wiki/1080i

Quote :

1080i is directly compatible with CRT-based HDTV sets and is displayed natively in interlaced form, but must be deinterlaced and often scaled for display on modern progressive-scan LCD and plasma TV sets. Depending on the television's video processor the resulting video quality may vary.

so your lcd TV is also progressive by nature just like your lcd monitor is.

Hdtv comes with big screens in 1080p.
LCD of pcs come with a smaller screen at 1080p normally.
why? Viewing distances that's all. Pc you sit up close. A big screen at 1080p will make certain things harder to see.
A hdtv you sit a distance back where the big screen is better than the smaller one then. That's about it with the two

umm yep if you have a 50'' TV u dont want to sit 2' away from it but he is buying a 24'' TV and that is a very typical size for a monitor as well.

Yes my graphics card can easily output 1920x1080, I am typing this msg down on same resolution. The question is that can that 24 inch lcd tv that outputs 1920x1080 as a tv, can it do the same when used for pc, provided my graphics card can output that resolution?

Reply to wroxtar

Doesn't matter now, that model is out of stocks, and supply has been put on hold indefinitely. Thanks for all your help, but I still didn't get the answer about why a full HD tv cannot output 1920x1080 resolution while being used as a pc.
