1280x1024@120Hz vertical refresh rate monitors? only 4 options?

[blahij]

Looking to see if anyone is able to help me with a list of fairly recent( last 4 or 5 years ) monitors capable of doing 1280x1024@120Hz. I have been searching awhile and seems hard to find the max refresh at certain resolutions (especially with sony), but from what I've found so far:

NEC DP2070SB-BK 22" 1280x1024@127Hz

NEC/MITSU FP2141SB-BK 22" 1280x1024@127Hz

Sony F520 GDM-F520 21" 1280x1024@129Hz

Sony G520 CPD-G520 21" 1280x1024@123Hz

It also seems the earlier models of the 2070 the 2060/2040 aren't capable, but I'm not sure. I can only compare there max res/refresh 2048 x 1536@75 Hz with others within that range and it seems there isn't enough 'bandwidth'( not sure if thats the right term, but have seen it on some spec sheets) to pull off the 1280x1024@120Hz. The same goes for all earlier sony monitors also, it seems impossible to find data on them.

Much appreciated if anyone is able to help.

Indeed, most monitors don't have enough bandwidth to display these settings -- but then again, neither do most video cards.

1280 * 1024 = 1,310,720 pixels/frame
1,310,720 * 3 (three color channels) * 120 (frames/sec) = 471,859,200 samples/sec.

Most new video cards only have 400Mhz RAMDACs (so they can output roughly 400 million samples/sec.), and will likely not be able to output this (or, if they try, there could be considerable noise in the signal). Likewise, few monitors support such high resolutions AND refresh rates simultaneously -- it's tough to find ones that will go over 100Hz at 1280x1024 or 72-75Hz at 1600x1200 due to the 400Mhz restrictions that most video cards impose (1280x1024@127Hz is almost exactly 500 million samples/sec., so the monitors you quoted probably support that, and should in theory run 1600x1200@85Hz). Except for 'professional' CRT monitors (designed for graphics artists and other people who run at super-high resolutions), it makes no sense to provide more that 400Mhz bandwidth on the monitor side, as it will be wasted by all but a handful of users.

Edit: a monitor capable of 2048x1536@75Hz must be able to read at least 700 million samples/sec. from the PC, and should easily be capable of doing 1280x1024@120Hz (although there could be other restrictions within the monitor that prevent such operation -- maybe, for instance, the vertical refresh is limited to 100Hz regardless of resolution).

it can do 1600 dots × 1200 lines @ 104hz, so i can imagine it should do 120hz at 1280x1024.
max refresh is 2048 dots × 1536 lines @ 80hz.

My question is, why would you want to run a 5:4 resolution on a 4:3 monitor? Enjoy distortion?

Even on CRT's, I've never been a fan of >100Hz refresh rates. It's all personal preference, but I prefer 75-85 Hz on nice Trinitron/Diamondtron screen to anything higher.

Maybe he's not running games with a fixed FOV and this isn't a problem.

Hmmmm that doesnt really make sense. Why would anyone prefer a lower refresh rate?
