are there any technical or quality advantages in rendering (native) 1080p over 720p upscaled to 1080p? Technical comments would be mostly appreciated
I guess you wouldn't notice much of a difference with the upscaling with quality TV or monitor (I'm guessing since I don't know first hand...still use a TV for my PS3 for the time being and my 19" CRT monitor for the 360).
1080p native is pixel perfect, 1 pixel rendered = 1 pixel on the monitor. 720p upscaled finds fancy ways to enlarge the 720p image
It entirely depends on your level of detail perception, the application and the hardware you are using. If you look at the pure numbers: 1920 x 1080 = 2,073,600 pixels 1280 x 720 = 921,600 pixels While the aspect ratio is identical, you lose 44% of the total pixels going from 1080p to 720p. The biggest problem is the scaling itself, since each pixel rendered in 720p becomes 1.5 pixels when scaled up to 1080p. Obviously, you cannot render half a pixel, so there must be some form of interpolation done on the pixels. An additional problem is the native resolution of the display device. Some displays which take in a 1080p signal may actually have a native 720p output. In that case you would be up- then downscaling the image, losing detail each time. A lot of people say that they do not see a difference between the two resolutions, but everyone is different. Personally, I see a huge difference between the resolutions when I work on something that I can control the original resolution. Of course, the 60" TV exacerbates the "problem". :icon_bigg
Supposedly the 360's scaler is really good, so 720p>1080p is still good looking or something. I don't have 1080p so I dunno.
I m curious, since most if not all 360 software is natively rendered at 720p yet the ps3 can render 1080p natively for some games.
Basically if your TV does 1080p then use 1080p, but make sure it has a 1080p resolution and doesn't just support 1080p. My TV does 720p natively but supports 1080i and 1080p, but although looks fine on anything moving it does look odd on things that are static like the PS3 menus.
This is slightly off topic but what am I after here? How can one distinguish what sets support 1080p and what sets actually "do" 1080p in between the lines of all the marketing jargon? I understand that "real" 1080p sets have 1920x1080 actual pixels on the set whereas the rest just downscale it to fit their 1280x720 actual dot matrix.
Thats the big thing to look for, the actual resolution. Lots of LCDs arent even 720p, they have extra pixels and such so even they arent truly native 720p. Look for one thats 1920x1080 though, that should do the trick ;P
Also be careful of the oddball displays that actually have a 1080 vertical resolution, but only a 14xx - 16xx horizontal resolution. I have only seen a couple, and usually this is a problem on low end high def camcorders, but it is still a problem. The best bet is to just find a decent review on the display as this is an item that usually is covered.
¿Nobody talks about the gaming lag? it's a really big problem, especially if you want to play technical games of past generations, or even, of this gen. I wanted to buy a Pioneer Kuro plasma, and it has lag even with game mode activated.
ah yes, what's with the lag btw? i noticed it when i put my 360 in 1080p on a Phillips! game mode fixed the issue though fully
The display lag is generally not going to be affected as much by scaling the image (in my experience) as it is by DSP's processing the image for the display technology itself (e.g. analog->digital conversion, digital->DLP/LCD). Though a very poorly implemented/underpowered scaler could be a problem.
I was really worried about lag but I dont even notice it (though i know its there) with my Wii on my 19" Samsung TFT.. even on Smash Bros Brawl it doesnt affect us.
The lag is also related to the resolution, check these links: http://en.wikipedia.org/wiki/Input_lag http://forums.shoryuken.com/showthread.php?t=94426 Barcode, the only tvs without lag, or very low (less than 30 milliseconds, which is almost 2 frames), that i've found until now are Sony KDL40W4000, Panasonic TH50PZ81 and Samsung LE32A656. you can check the reviews here: http://www.hdtvtest.co.uk/ And If you want to check the lag: http://tft.vanity.dk/inputlag.html You have to connect your laptop to the screen, or have a PC with two video outputs; if you can connect one to a CRT monitor you'll get better results, because it will not have lag. You need the main screen on mirror mode, start the clock, and then, make a photo of the two screens; one of them will be slower, so you'll only have to check the difference between, and you'll get the lag of your screen.
Hey Barc0de. I sort of recently got a 47 In. Phillips that supports 1080i and 1080p. =] But I was wondering where you select this game mode at? I have heard about it... but maybe only some models have it? :crying:
well it's in the smart settings thing i think. The one i m talking about has ambilight and is quite recent..
That must be it... because I searched everywhere for that damn Game Mode. Ahhh well, I have actually gotten used to the Lag. :lol: Thanks anyway! :nod:
