A question about TV and resolution

What you mean a 1024x768 TV? There should be no difference because your TV will only display 720 lines, either putting thin black bars at the top and bottom or scaling the image to fit the whole screen. You'd still get "true" 720p provided you've connected the console properly.

What happens with an High-Def image (720p or 1080i/p) if its spanned across a 4:3 screen? Is there loss in quality? Lines have to be added or subtracted to fit the screen itself...hmmm....or is there something else?
The TV is marked "HD Ready" and has 1xDVI and 2xcomponent. I guess am safe then.DemoCoder said:

How is it with plasma and gaming, is burn-in a real problem anymore?
on 4:3 crts, when displaying a widescreen image, usually they just squeeze the output down so there is no loss in the tv's resolution.
on some other types of tv technology, such as FP DLP they do cut the pixels though, so you will lose some resolution.
when 1024x768 (a common Plasma resolution for 42" screens) is used on a 16:9 set, instead of square pixels they use rectangular ones

No, not really since a CRT still has far superior color reproduction and the ability to display multiple resolutions in their "native" format if the Monitor designer chooses to do so
My Philips TV will display 480i/p and 1080i just fine without all of the crap associated with using a fixed resolution display such as a plasma or LCD

I believe the poster above you was talking about specifically burn-in and not the actual quality of Plasma and LCD being comparable to CRT.

If we are talking about a standard 4:3 profile for this 1024x768 "TV" and the "720p game" is in a true widescreen format (16x9), then that image will have to be letterboxed to appear properly on that 4:3 TV. That will incur some loss in vertical resolution, regarding the parts of the screen that are actually occupied by the image. So that 720p image will technically be a "614p" image, as presented on the TV screen. Whether or not that reduction is enough for you to really see a difference is up to personal perceptions. I'm just saying, technically it is a reduction in resolution as a consequence of matching a widescreen profile to a standard profile. (Now if this "TV" you are describing is actually widescreen and 1024x768, then you stand a good chance to achieve the full 720p resolution, but not w/o the sacrifice of some horizontal resolution- 1280 ==> 1024)

I wouldn't touch a display that can't show 1280x720 or more and usually you can get a model that achieves this at the same price as this handicapped model.
Only if the DVI plug offers DVI-I; PC monitors typically do, while (flatpanel) TVs more often seem to offer DVI-D instead: thus digital only.MistaPi said:
All that a DVI-VGA dongle does is take the analog pins present in the DVI-I connector and route them to the correct pins in a VGA plug. It doesn't actually convert a digital image into analog VGA; for that you need a much more advanced setup.
Can't say I agree with this. Compared to fast reaction time 6-bit per channel LCD panels I guess you're right, but these don't seem to be used in TVs anyway. Compared to proper 8-bit per channel panels, CRTs have no advantage at all from what I as a layperson have seen, and that's likely the case with most other people as well.YeuEmMaiMai said:
Plasmas have AFAIK even better colors and certainly much greater contrast than LCDs. I've seen plasmas with advertised contrast ratios of 8000:1 (10x of a good LCD), this should be far greater than any CRT.As they don't have a native format they can show pretty much any res, though due to the analog nature and the fixed, finite resolution of the phosphor dots of the screen, they get blurrier the higher res you show on them. Limited video bandwidth of the analog components also means refresh rate goes down as screen res goes up, with the risk of flicker appearing. I'll take the pin-sharp and flicker-free image of a fixed pixel device at native res any day of the week over that.
All the crap, you say? What about geometry distortion (pincushion, bowing, etc), poor convergence in some corner, bad focus in another, having to manually trim the display so each resolution fits the screen (and having it shift as the unit heats up), moire patterns appearing in certain imagery, etc... It's not as if CRTs are exactly problem free, you know.
Large-screen CRTs also are very heavy, burns a lot of power, are very bulky, and so on. Comes with being based on nineteenth-century tech. I've lived with CRT monitors for 10+ years using various computers and I'm completely fed up with that old shitty technology. CRTs are basically obsolete for 99.9% of the population, if not more.
I am considering a Philips 37PF7320 LCD-TV with 1366x768 resoluton and DVI-I connection. But it has limited connections so I have to get a DVI splitter/switch for my DVD player, Xbox360 and possible PS3 in the future. But this should work fine right, with a VGA to DVI adapter connected to the DVI splitter/switch?Guden Oden said:

Yes it should work, you need VGA to DVI-I adapter to plug in to the DVI Switch and then DVI-I cable from the switch to the tv and it should work.
Well, PERHAPS. If the splitter routes analog signals. Also, x360 doesn't have digital output, so you'd definitely need a splitter that handles analog.MistaPi said:
Also, you don't NEED to get dual-link cables as hardly any consumer equipment is dual-link anyway, but are single-link cables really any cheaper? Btw, do a dual-link cable even FIT in a single-link DVI-I/D connector?
I'm not sure. Just get a DVI-I single-link cable if you're uncertain, that'll work fine.Guden Oden said:Well, PERHAPS. If the splitter routes analog signals. Also, x360 doesn't have digital output, so you'd definitely need a splitter that handles analog.

All I have are dual-link cables and they work fine with whatever I use. There is usually a nominal price difference.
