Please note that I have a 30 inch monitor (Dell wpxxxx). I have a
nVidia 7900 gtx video card and I am using the latest drivers.
When I am trying to change my screen resolution to 1920x1080 or 1280x720, I am getting a black screen.

I don't have any trouble to change my resolution to 1280x768. Would I
also benefit from hd when I play 1080p content over 768p (1280x768).

What could be the problem?

[compucv621]

I don't believe that monitor goes up to that high of a resolution, can you please post the entire model number? Also, try downloading the nVidia control panel to see if there's a setting in there. Personally I have an ATi card that shows HD modes you can display, but I'm not sure if nVidia has a similar system. You may also want to try a DVI cable if you aren't already. Most 30" monitors are QXGA or WQXGA, but it looks like yours isn't if it can't show that resolution.

[mjd420nova]

I think that resolution is only available if you have a widescreen monitor.

[crazy4laptops]

the monitor is probably being forced out of it's native resolution.

I've played 720p content on my computers it looks fantastic, I've tried 1080p and my computer can't handle it. 1080 causes a big system resource hit vs 720.
make sure your color/white balance is set right for optimal picture viewing, and the better black level and higher contrast ratio, the more amazing the movie/video will be.

but you aren't missing much by staying at 720. (it's only a 312 line difference, which makes the total picture size about 3 inches bigger/smaller) At the best viewing distance you wont be able to see the difference.

My monitor supports up to 2560x1600, it's a Dell 3007WFP

I am able to run the nVidia Control panel, from there I can see the option to "change the signal or HD format (1080p hdtv, 720p hdtv).

In Vista I didn't have any problems to enable hd resolutions, I believe Windows XP doesn't natively support hd resolutions (I have SP3).

I am already using a high-end dual link dvi cable.

[alexdemaet76]

I believe I am not even looking at 720p content when my monitor is running 2560x1600 resolution, by default I believe it's only 480p!

I have some movies with hd content and Cyberlink Powerdvd can do some kind of dvd upscaling. So it should be really useful for me to enable a hd resolution.

I don't want to install Vista again, maybe I will have to if there's no other sollution for hd playback

[compucv621]

To be honest I've never even seen a PC to 1080i. I didn't think it was possible unless you had the latest and greatest graphics cards.

[alexdemaet76]

You don't need an expensive video card to be able to run 1080p, some video cards do the hd rendering on board which saves the cpu.

[alexdemaet76]

Has anyone tried to change the resolution to 1280x1080 (720p) or 1600x1080 (1080p) in Windows XP?
Do you also get a black screen? Please report.

I am sure my monitor is capable of running those resolutions.

Are you basing the quoted statement on fact or opinion? Have you actually checked the owner's manual of the monitor to confirm that the two resolutions in question are supported by this monitor?

I have a 40" monitor and two 30" monitors and all of them support the resolutions you list with no problem. I am not at home right now to confirm the full range of my monitors' resolutions but I know all of them support the two resolutions you need. That being said, I would say that all 30" monitors should be able to support the resolutions you need; however, it is best to confirm that by either looking through the manual, going to the monitor's specification page on Dell's website, or contacting Dell directly.

[alexdemaet76]

I haven't checked the manual, but as I stated before that I was able to run the 720p and 1080p resolutions (while playing hd content in Cyberlink Powerdvd) in Windows VISTA (this os has native hd support). I would love to run those resolutions in Windows XP because I don't want to install Vista anymore (at the moment).

[mphenterprises]

Okay, well here is what I will do. I have a Dual Boot system (Windows XP & Windows Vista). As mentioned, I am not home right now to confirm this but if no one can assist with your situation by the time I get back home (Friday night...sorry, I know that is a ways away) I will confirm that I can use that resolution in both Windows Vista and Windows XP.

[alexdemaet76]

I have contacted Dell support and I hope they will provide a useful sollution.

[rtfire1]

xp will run in hd vista just runs easyer. I think you might want to see what your video card can do under xp. I have found some drivers for xp are lacking do to more new systems running xp in my case my laptop can not play sound when using xp or xp 64

OK, first of all, 1080p is a resolution of 1920x1080, not 1600x1080 and 720p has a resolution of 1280x720, not 1280x1080.



The second thing to note is that 1080i, 1080p, 720p, 480p, 480i, etc are generally used in terms of HDTVs. They both describe a resolution (the number part) and how that resolution is achieve...through progressive scan or interlacing (the letter part). It should be noted that to my knowledge ALL computer displays when used as a computer monitor are progressive scan. Thus, one does NOT usually worry about ps and is when talking about computers....you tend to strictly talk in terms of resolutions, which are specified by the two numbers...horizontal and vertical lines of resolution.



As such, the resolution you can achieve will be dictated by what you monitor can achieve in combination with what your graphics card is capable of displaying. Now, technically, most computer monitors will struggle with a "true" HDTV 720p or 1080i/p...but this is due to the TV variants being a different aspect ratio than what is typically used in computers. Computer wide screens tend to be 16:10 or something closers to 16:10, while HDTV screens (and their associated aspect ratios) tend to be 16:9. As a result, while 1280x720 is the "official" 720p (it gives you nice square pixels), 1200x800 and 1280x768 (both "computer" resolutions) can also be classified as 720p and will display 720p content. In the computer world, you generally have either 4:3 screens (the old variety of more "squarish" screens) or 16:10 screens, which are the new "widescreen" versions.



Now, it would appear that your monitor is more that capable of handling 1080p/i type resolutions, but it is not clear if your graphics card can. It would appear that the card itself can handle the resolutions, but it is possible that the XP driver for the card might limit the resolution. In reality, my guess is that you can achieve the needed resolution in XP, but rather that XP does not have built in functions to output in specific HDTV format (i.e. specifically for output meant to be displayed as a TV signal on an HDTV rather than as a computer video signal on an HDTV...this is likely the "bit" you see in the nVidia control panel about 720p and 1080p when running in Vista...Vista has the associated HDTV "stuff", which includes things like HDCP, copy protection for HDTV signals). I am guessing that you will be able to set Windows XP to a resolution that is at least 1920x1080 or better.



This leads me to the question of what are you specifically trying to display? Is it a BluRay disk? Something else? Keep in mind that computer resolutions are generally higher than that of TV, even HDTV. In computer terms, 720p is a rather average to low resolution. 1080i/p is an average to slightly high resolution generally in computer terms. Computers have been "high definition" for quite a while...when compared to traditiona TV (480i/p, which is 640x480 or what is commonly referred to as VGA).

[alexdemaet76]

>>This leads me to the question of what are you specifically trying to display? Is it a BluRay disk?
Yes, I am trying to display hd content.
I believe the 1920x1080 resolution and the 1280x720 resolution are not supported in Windows XP (in Vista however, I had no
troulbe at all to display those resolutions; Dell is telling me that those resolutions can't be displayed as well in Vista - see below).
This means I will set up my resolution at 1680x1050 in Windows XP for displaying HD content.

I have received a Dell support reply: "

This are the resolutions in which the display can be used.

In the video driver settings you may change the settings acording
the display optimal resolutions to get the best few.

720p and 1080p are not supported by graghical card nor by the
display.

I am responding to your question on a 24" HP w2408h monitor connected to a custom built (by me) computer with an Nvidia 8600GT graphics card and on the HD with XP SP2. The monitor is displaying at 1920x1200, it's native resolution. (I normally use either 1440x900 or 1680x1050 as it is easier on the eyes).
It is not your monitor, it is not Windows XP, I believe it is a limitation of the graphics card. The 7xxx series came out before the push to the large wide monitors and the HD content.
If you want to use the 720p/1080i/1080p resolution, you will probably have to get a card with HDTV output as well as DVI. While some 8xxx cards can be found with both VGA and DVI as well as HDTV, most come with two DVI connections and either one or two DVI to VGA adapters.

My point is that you should be able to set a resolution that will allow you to display HD content just fine. You might not be able to do it "full screen" and get optimal results, but if you say have a BluRay drive, you should be able to play it in a window and get the full resolution IF you set Windows to an appropriate resolution (and assuming that you have drivers and software that is capable of playing back the full HD content...I don't know how XP deals with HDCP...it might not be able to do so, and thus you might get "downscaled" resolution from a BluRay HD disk in XP). 1280x800 is basically equivalent in resolution to 720p, it is just a different aspect ratio. As such, it can display 720p, but it might be a little "warped" due to about 80 lines of resolution of the monitor NOT being used in play back mode of 720p...which will make things look a little warped as the pixels will NOT be square, but a little "squished". 2560x1600 is a higher resolution that 1080i/p, which means it should easier be able to play back 1080i/p content in a Window with the FULL resolution of the 1080p/i signal...assuming you have software and drivers to handle such playback ability with BluRay HD disks in a BluRay drive.



The point of me asking the question is that depending on what you are trying to do, Windows XP might not be capable. In order to play back HD content from commercial BluRay disks, you generally have to have all HDCP compliant hardware and software. In Vista's case, if you don't it will not play back at all or at high resolution since Vista has HDCP included. With XP, you might be spared that problem, but you still need software and drivers that can deal with such stuff effectively. Beyond that, Windows XP CAN handle that level of resolution...but they might not be able to handle the actual 1080i/p or 720p stuff such that BOTH resolution AND aspect ratio are replicated.

smax I have now read up and found that I i need to kick up my out put to my screen on my laptop I also found out xp has a lotof issues with 1080 and 720 unless its media center 2005 in that case it works fine most of the time for play back.

Again, my point is that is not technically a "resolution" issue, but more likely a TV format vs. computer format issue. XP has ZERO trouble getting resolutions at the same level or better than 1080p, but 1080p is not technically JUST a resolution...it is also an aspect ratio AND an implied TV "format". Thus, you need to deal with more than just whether or not it has the appropriate level of resolution, but also the aspect ratio and all the other "stuff" that comes with HDTV content such as HDCP, etc.
