Can computer Led/Lcd monitor upscale lower resolution video to fit in higher resolution screen?

Q. Ok it's probably a noob question.

As far as I know HD led/lcd tvs can upscale lower resolution game video/frames(ps3 xbox 360) to fit the whole screen.

So I need to know can computer monitor with hd resolution support (1920x1080) upscale 1360x768p resolution game video/frames to fit the whole screen?Or I need to play at native 1920x1080p resolution so that the monitor can fill the whole screen?Is there any special type or model of any Lcd/Led monitor that can upscale Pc game's frames from lower resolution to fit the whole screen?Is this any special feature for computer Led/Lcd monitor?If so what is this feature is called/named?Do different manufacturers lcd monitor have different names of this feature?

the reason I am asking is because I play at 1360x768p resolution on 16 inches lcd monitor and now I am thinking about updating to a 1920x1080p monitor.But if I play at 1360x768p resolution will there be blank spaces around the edges of monitor screen or the monitor will upscale the game frames to fit the whole screen ?
ok those blank bars do make me feel the monitor is not used to it's full potential

kind of makes the monitor feel empty and game screen with black bars also feels

quite weird to me.

So what is the aspect ratio of 1360x768 resolution 16:9 or 16:10?Will it upscale and fit to 1920x1080 resolution monitor or leave blank bars outside the game frame?

A. 1360x768 is 1.7708333 ratio. 1920x1080 is 1.777777 ratio. Very close.
16:10 is 1.6 ratio. 16:9 is 1.77777 ratio. As you can see, the 16:9 ratio screen best fits both the resolutions you are trying for.
But there is a cost to upscaling. Since you cannot manufacture greater detail out of a lower resolution signal like 1360x768, what upscaling does is to add in duplicated pixels every so often. Since there are (1920-1360 = 560) more pixels to put into the picture, that means somehow those 560 pixels are added over the spread of 1920 pixels. About every 3.42 pixels another one is added. Actually it goes 3,3,4,3,4,3,3,4,3,4 etc. As you can see, a lot of duplicates are added. The resolution is not any better. It is just expanded to cover greater area of screen. It does get fuzzier if you compare side by side. But you are supposed to view from a greater distance so you will not notice.
And, I think the standard is 1366x768, not 1360x768. That gives a 1.7786 ratio.


How long do LCD monitors typically last?
Q. I bought an Acer X163W LCD monitor from wallmart for $99.99, and i was wondering ho long it will last in a 24/7 media environment. I've already had it on for 4 months 24/7 and don't notice anything changing with image quality and brightness.

A. Typically the backlight is rated 50,000 hours, so do the math to see how many years that is. 50,000/24/365 = 5.7 years. Multiply that by 3 if use averages 8 hrs/day. However, if other electronic components are overrated or substandard, or you physically fatigue a connector or break something, that may shorten its life.

Of all the laptops and LCD monitors/TV's at home or small office at work, I have only seen one failure. A 17" Dell LCD monitor failed at work, but not sure exactly what the issue was, maybe a fatigued VGA connector. At first it would fail to wake from standby unless I jiggled the cable. But eventually it was just a black screen with blinking green power LED (which was usually solid green when on or amber in standby). Same cable works fine with different monitor.

I have a PIII 500 laptop purchased Jan 2000 that still works. And I left it on 24/7 for a couple of years as a wireless terminal for a PC in my basement. Although, the display did go into standby when not in use. I have not fired it up much lately other than to get some data from it (dual boots Win98se and Linux).
