Monitors that do 2048 x 1536?

[dhopton]

Hello.

I'm in the market for a new monitor. I'm looking for a 19" (or a 21" if the price is right) that will do 2048x1536 @ 60hz. I know the Viewsonic 795 does this, but it's not available anymore. Does the iiyama 450 Pro do this res?

If you have a 19" monitor, you could be really kind and have a go to see if it does, esp if it's an iiyama 450 Pro. Just faf around with the mointor database, and see what happens...

THANKS!

Are you sure you want to run at 60hz? It's going to flicker something awful.

As a test, at 1600x1200 on Nokia 445XiPlus from my normal refresh of 75hz down to 60hz. It looked terrible and had a very disconcerting flicker.

I'm currently running my iiyama Vision Master 17" (from 1996 I might add) @ 1600x1200 @ 65hz. I used to run it at 60, but I discoverd the 65hz option the other day. It will do 1792x1344 @ 60hz and also 1856x 1392 @ 60hz. These are not mentioned any where in the docs for the monitor.

I'm just trying to see if I can push current monitors as much. And I cant see the flicker on this monitor... It maybe just be me...

Hi!

I run at 2048X1536 @ 75hz.
I have a 21" Viewsonic P817.
My graphic board is Matrox Millennium G200 SE.

Bye!

I also have a ViewSonic P817, paired with a G400 MAX. I run 2048x1536x32@75Hz regularly in Windows 98 SE and Solaris x86 with no problems. It's a bit tiny, but it's flicker-free and you can't beat the desktop real estate! The image is crisp and sharp and the colors are great, plus the P817 includes USB-based software to control all the geometry settings directly from Windows (in addition to the usual front panel buttons). I highly recommend it! At this resolution it is probably worth getting a VGA-to-BNC cable so you can use the BNC inputs on the P817.

Hi!

I got my P817 10 months ago.
I run at 2048X1536X16@75hz.
It's flicker-free.
According to Viewsonic documentation, I am supposed to get 85hz at 2048X1536 but I not able to get 85 hz at 2048X1536.
Do you know why?

But, during the last 4 weeks, it is no longer flicker-free.

I have "flicker" at the left and at the right of the screen.
It is no longer workable at 2048X1536 because I have too much "flicker".
I have the same problem with 1800X1440.

Could you explain why it was flicker-free during 8 months?
I have a Millennium G200 SE.
Do I have to get Millennium G400 to get back flicker-free?

Now, I must use 1600X1200 to get flicker-free.

Thank you very much! Roger

Hi Roger,

I have no idea why your P817 has developed flicker at the edges of the screen. It doesn't make sense that the monitor is going bad after only 10 months, or that there are any problems with your G200. Have you changed the position of any electronic devices or peripherals around your computer and monitor? Perhaps there is something that is causing electronic or magnetic interference. Sometimes a degauss or adjusting the horizontal and/or vertical moire settings on the monitor will cure this. Also, some types of interference are specific to a particular refresh rate. If you move from 75 Hz to something slightly different like 73 or 77, you might eliminate the interference.

The reason you can't get 85 Hz at 2048x1536 is most likely because you are using the G200 SE. I believe that the G200 SE has a max pixel clock of 320 MHz. The G400 MAX has a max of 360 MHz, and this is necessary to get 85 Hz vertical refresh. The P817 max input clock is also 360 MHz, making the G400 MAX and P817 perfect companions. I don't recommend running at 85 Hz however, because this is really pushing the limits of both the video card and monitor. When I tried this, I couldn't expand the picture to reach edge-to-edge on the monitor, and the edges also seemed to show some aliasing.

I highly recommend that anyone who is interested in pixel clocks and refresh rates and resolutions and all that jazz read the Linux/XFree86 video timing HowTo (sorry I don't have a link, but a quick web search will find this). This explains how all the different frequencies and resolutions of your monitor and video card are related, and will also tell you what all the options in the advanced Powerdesk monitor settings dialog mean (like front porch and back porch). Most of the information is very useful even if you have no intention of ever running Linux or XFree86 on your machine.

As a general rule, just about any monitor with a maximum horizontal scan frequency of at least 96kHz can reach 2048x1536 at 60Hz.

The Eye-Q 777 that I use here at work maxes out at 2048x1536x32bpp@77Hz, but that would require a MAX (RAMDAC wise), thus I'm stuck with only 66Hz ...

Hi,

My F400 can do it, but I do notice the
flicker. At 1600x1200@85Hz the image is
great and the text is very clear.


Regards,
Ricardo

The iiyama pro450 goes up to 1800x1440 @ 77Hz, you will have to get the pro510 for 2048x1536 @ 75Hz.

Hi Mark!

First, thank you very very much for your answer.
I appreciate.

You are right! I have effectively a new electronic device around and it is the Microsoft Intellimouse explorer. So, I will return back to my old mouse for some weeks.

You are right! G200 SE has a max pixel clock of 320 MHz. So, next monday, I will order a G400 MAX to get 85 Hz at 2048X1536. I love this resolution.

Thank you again! Roger

Hi Mark!

You said :

I also have a ViewSonic P817, paired with a G400 MAX. I run 2048x1536x32@75Hz regularly in Windows 98 SE.

Are you able to get 85Hz at 2048X1536?

I'm about to buy a G400 MAX to get 85Hz at 2040X1536 and I want to be sure I will get 85Hz at 2048X1536.

Thank you very much! Roger
