In a total dilema at the moment about which new/additional monitor to purchase.

Toss up between the VX2025wm to go with my existing VX912B or stretch a little and go for the 2407WFP.

I've read a few posts saying that the Viewsonic (with whom I've had NO problems ever) doesn't support 1:1 pixel mapping - what does this, in laymans terms, mean?

Does it mean that the screen is incapable of showing a picture of a native resolution of 1280x1024 but stretches it to the proportions of the widescreen?

Bit miffed off 'cos OcUK have the offer on at the mo for the 2407WFP but won't be buying until Friday, so gonna miss out on that one, but likewise, heard on an independent review board that the 2407WFP is a good monitor, but there are reports of inconsistancy in it's quality (even over the A02 range).

Ideally I'll be making a purchase that will last a few years. The Dell offers a good future proof system, especially seeing as I'll also be using it as an additional console monitor so those additional inputs will be more than welcome, but I really fancy the idea of using 2 monitors for work at home, but can't see how the hell I'll fit my existing 912B AND the Dell on the same desk!!

But back to the main question, how is 1:1 easily defined?
 
Re: 1:1 scaling; 800x600 would be shown 800x600 pixels, i.e each pixel fed into the monitor is output on one pixel on the monitor, with no scaling done.

For example, a 1920x1200 monitor would display an tiny 800x600 image in the middle, with (1920-800)/2 'unlit' pixels to the left and the right of the image, and (1200-600)/2 unlit pixels above and below the image.

It is fairly pointless, aspect scaling (filling the screen without distorting the image) is what you really want with widescreen monitors, an 800x600 image would be scaled (effectively) to 1600x1200 (i.e. remaining at 4:3) with (1920-1600)/2 blank pixels either side of the screen but the entire vertical plane in use. However, I guess a monitor without aspect scaling but with 1:1 mapping would be more usable in that you could run 1600x1200 1:1 and experience full screen viewing with no aspect distortion - a screen with neither option will always stretch the input image to fill the screen, causing 'normal' (4:3) images to be stretched.
 
I just bought a pair of Dell 2407's Rev 02's from OcUK and there is no ghosting, or banding on either panel while running the screen in 'desktop' mode. Some banding is present if you enable the Multimedia, or Gaming mode, but while actually playing games I've yet to notice it. Although to be honest I think it looks great just leaving it in Desktop mode all the time, and lowering the brightness from the default 50 down to 40.

One screen is flawless, the other has a single stuck off 'red', but its not in a vital part of the screen and to be honest unless your searching for it, its pretty hard to find even though I know where it is.

The Dell screen has 3 modes of operation 1:1 pixel mapping, forced 4:3 and stretched. So its really nice for running older games which dont support 16:10.
 
Well that's a damn good explanation so thanks for that.

So regards the XV2025wm (which I'm edging more and more towards), does that support aspect-scaling as I can't seem to see whether it does or doesn't
 
My VX2025 arrived this afternoon.

Just hooked it up and I am using it now, first impressions, I am struggling to get used to Widescreen! But im sure I will in a couple of hours/days! LOL

For me, there was no other choice, Viewsonic was the only option I considered! :)
 
I have one...and the 2025 is a lovely piece of kit. The colour in the viewsonic are among the best I have seen on any TFT. My mate has a dell 2007FP and withough a doubt, the colours on the viewsonic is best.
 
my vx2025 arrived this morning, i haven't opened it because i can't decide wether to RMA and get the 2007, will take about a week to get the money back on the viewsonic, i really dunno what to do

i will be mainly gaming on this screen but also a lot of surfing and movies

:confused: :confused: :confused: :confused:

Really? I thought otherwise, but then I wasn't that impressed with either one and plumped for the NEC in the end.

No.
 
It doesn't do the aspect-scaling? O heck. So that means some of the images are gonna be stretched then?

Does the VX2025 come with a DVI cable?

The VX2025 CAN do aspect scaling.

See the pictures I posted of mine in this thread here.

Now some people HAVE had problems but it works for me with an Nvidia graphics card which supports it through the drivers. I think ATI cards might need more tweakage with Rivatuner if what I have read is correct, as apparently the drivers don't have the same options.
 
thanks for those pics. This was one of the main models which people were having problems with with the software aspect scaling. I'm beginning to think it's possible through software on nearly all monitors, perhaps even on all of them when done correctly. Might need other software besides the NVidia drivers like perhaps Rivatuner but interesting to see anyway.
 
Well, I'm about to order the VX2025wm.

As much as I'd like the Dell, I've got to think with my head and the reason for the two monitors is work related so gone for the more sensible option.

Never had a days bother with a Viewsonic, they're not the most expensive but they've never let me down, so, guess it makes sense.

Thanks for the clear up regarding the aspect-scaling MacX, thankfully I'm using an Nvidia 6800GT so if there are any issues regarding hardware compatibility, I should be in the good-camp.

Right, off I go to order...

Thanks again for all the feedback folks, really appreciate it.
 
I can't do the scaling through the drivers :( But im not alone... It seems to be a problem with Nvidia drivers & the latest 7x00 cards... I have a 7900GTX.

Will be fixed in a driver update I hope as the options are there.


I only play one game that I need to scale, thats Red Alert 2 Yuri's Revenge, as if I manually change the ini to 1680x1050 it works single player, but I can't quickmatch with that :(

Cmon Nvidia! :D

I am beginning to agree with this. I was up late night testing a 7900 with the VX2025 and couldn't get it to work even though it was fine with an older 7800GT. Probably get it to work with a 6800. Might try it later this week.

Someone on another thread mentioned the EDID table for the monitors. Maybe it is something to do with the way that is interpreted by the card and drivers. I wonder if that's a problem for the card or monitor manufacturers?

*Baddass*
Do you have any industry contacts who might know? :)
 
Well I'm not technical in this at all, but ordered mine and should be here tomorrow so will see how to confirm the issue (on a 6800GT) and post back in baddass's section.

Might need some help on what to do though! :p
