Windows 7 - Force DVI/HDMI resolutions and refresh rates

ok, this is a bit beyond my capabilities, but i think its my only option at this point. i have a syncmaster 2343bwx and cant get it to display its native resolution, either with the dvi OR the vga cables. seems as though windows 7 doesnt recognise the monitors capabilities properly. the native resolution should be 2048 x 1152 but all i can get is- dvi: 1280 x 720 and vga: 1920 x 1080 any help would be GREATLY appreciated

Hi everyone,

Got the same CRT limitations (60hz at any resolution) like many of you (windows 7 an XP). I read your article and tried to extract EDID with Phoenix but the list is empty. Seems that my monitor is too old to be detected (dunno).
It's a Iiyama 19" 1451. Is there a way to make a driver another way or any tricks that may help. I'm desperated and dont know what to do to make it work.

This worked great!!!! An online MMO I play only allows me to set resolutions based on native resolutions for my display. When I upgraded to windows 7 from vista, I lost all my 1280x### resolutions. This work around gave me back my favorite game and solved a MAJOR annoyance.

Thanks so much.

Argh... I had a similar problem to ESElrond a few pages back - I couldn't get the EDID out of the monitor at all (Samsung 1200NF), although it's supposed to support it. The short version is, the problem was I was using a VGA->5BNC cable.

Once I hooked up VGA->VGA (via DVI adapter), I got the EDID fine and none of this hackery was even necessary for me (but I appreciate the effort put into the tutorials regardless!). So, I just thought I'd post this just in case someone else is in the same situation - try a different cable first!

The weird/frustrating part was even in Windows 7 it worked fine with the VGA->5BNC cable, with no EDID info, as long as it was connected to the on-board graphics (HD 3300), which has a VGA port. Then I bought a HD5770 which is DVI only so I had to use an adapter, and was unable to go above 60Hz in any mode. With the on-board I could get all the same modes I always had in XP (1600x1200 @85 is my normal mode). I could not get EDID via the on-board adapter either - it showed up as "Generic non-PnP". Installing the Samsung INF (which I had to hack) made no difference. Overall a very frustrating night but I'm glad it's working now.

Hello!

I have a problem with my Iiyama visionmaster pro 454 (ref : HM903DT)

I have made a .inf with, I think, the right values but ATI catalyst just allow me to do 1024*768 at 120htz, instead of 1280*1024... I have a 5870 .

can you help me?

I've got the same monitor. The monitor doesn't allow 120hz at 1280x1024. Only up to 1280x960. After that you'll gonna have to use 100hz.

can't do more than 85htz on 1280*1024 :'(

Hi!

Red thread from beginning and done my own monitor.inf by Monitor Asset Manager. Windows 7 said that it have already best driver to non PnP monitor etc.

My display monitor is 22" Sony G500 and I have nVidia GTX 275 graphic card with newest WHQL drivers 196.21. Windows 7 is RTM 64-bit edition (Ultimate). My target is resolution 1280 x 960 @ 100 Hz. I cat get it easy to Desktop, but at games refreash rate drops back to 85 Hz.

SoftMCCS couldn't read EDID or DDC/CI. Maybe becouse I use DVI-VGA dongle. Phonenix EDID Designer shows only blanko screen.

So I download the "PED_HELPER (macros free version 0.2).xls" file and done my own EDID.dat file and red it by Monitor Asset Manager and created new monitor.inf file. But when trying to update monitor driver, Windows 7 said that it have already best driver for it. Is there way to force this driver loading?

I have tryed RivaTuner, PowerStrip and Refresh Rate Patcher 1.0.1 and some early refrash force programs from WinXP. No help. By default nVidia 196.21 drivers let me choose right refresh rate to Desktop, like 100 Hz to resolution 1280 x 960, but when I start game, max. refresh rate is still 85 Hz.
Becouse my English is what is it, I attach some pictures here. How you see, all settings seems to be OK, but at games highest refresh is still 85 Hz. I think I need to find way how to force monitor.inf or I didn't make it right.

EDIT:

I got it work!! There is one place where to **** up, when offering new own monitor.inf driver to your monitor. Control Panel/ System/ Device Manager/ Monitor, Generic Non-PnP monitor, right click "Upgrade device driver". Choose "Find driver from your own computer". Here is the place where I sucks and waste my time and hairs. Don't start browse here and offer your driver here, becouse Windows 7 say that it have already best driver etc. Choose below link "Choose device driver from this computer". No you see box, where is Generic Non-PnP Monitor and Generic PnP Monitor. Now you see button "Disk...". Press it browse to your own monitor.inf. Windows 7 pop up warning box etc. Now just reboot and you have your refresh rates on your games too.

Damn it I am happy now. I have wasted about this since first Windows 7 beta versions and therefore still used WinXP.

Thank you!!!

It was really pissing me off that Windows 7 wouldn't let me set anything other than 75Hz for my Sylvania F89 CRT. This was especially annoying because Battlefield 2 would not start at all unless the monitor supported 60Hz mode!

Following your guide to the letter, I was able to (rather easily) enable 1600x1200@60Hz mode for my display. I also unlocked resolutions up to 2048x1536@60Hz, since I knew from Windows XP that my monitor could handle them.

By the way, if anyone gets an obnoxious error in Phoenix on page 1 of Detailed Timings about how "Pixel Clock must be between 1000 and 655000", just ignore it. You can safely leave that value at 0, set to read-only mode, pick a different page, and go back to edit mode.

Thanks. After all the research I did to come up with this guide I got mostly complaints. As a result I left this site and have only recently come back. I've also seen many of my techniques used for driver issues and such so I'm happy to have helped. I think Windows 7 is off and on it's way so thanks for all the fish!
