Custom Resolution Utility

[Goliathus73]

Hi can you you help! My Monitor will overclock to 75Hz so I make a custom res of 75Hz and restart my PC. Without selecting 75Hz and leaving it on default 60Hz when I play Sleeping Dogs its only showing 1920x1080@75Hz no 60Hz option? Browsing windows and checking monitors refresh rate it is 60Hz.

That's a game-specific problem. Sleeping Dogs will only use the highest refresh rate for a given resolution. I don't know any way around that except to create a different resolution like 1919x1080.

Newbie here - sorry to jump into this thread but;

I have a Win 8 PC with a Syncmaster SA850 monitor which has a native resolution of 2560x1440 and an Nvidia GT635 card until recently all was well. THEN - I did a windows update to 8.1 and from that point on I cannot get the monitor to run at native resolution.

Samsung and Microsoft were no help at all - I have called them many many times. The only solution they came up with was to downgrade back to Win 8 which I have done with a completely clean install from the OEM disks.

I know that this video card and monitor combination can work because it was working for months before the win 8.1 upgrade!

I can set up a custom resolution in the nvidia panel but the monitor remains at 1920x1080 although the video card is clearly sending 2560x1440 because all the icons etc shrink. But because of the monitors setting the display is really fuzzy.

Odd thing is - this monitor as a 'dual screen' facility where you can have 1/2 the screen allocated to one input and the other half to another input. If I select that, with only one cable attached, I get a great 1280x1440 but of course only 1/2 the screen.

I tried the CRU but that did not seem to work.

Desperate........any ideas!

Is the monitor connected via dual-link DVI? If the video card is actually sending 2560x1440, then the monitor can't be at 1920x1080. Check the monitor's menu in the information section to see what resolution the monitor is actually receiving from the video card.

If you see 1280x1440 with dual-link DVI, then the monitor is only receiving a signal from one of the DVI links, which would explain the fuzzy picture. Usually that only happens if you're using the wrong type of cable, but even if that were the case, 2560x1440 should still be selectable without a custom resolution.

If that's happening with a dual-link DVI cable, then it's likely an NVIDIA driver bug. It's like the driver is treating the dual-link DVI port as a single-link DVI port, which is why 2560x1440 isn't available, but then when you try to add a custom resolution, it still tries to split the output into two links but only sends out one link.

If you see 1920x1080 when trying the custom resolution, then the video card is scaling the resolution down. In that case, select the "CVT reduced blank" timing standard and make sure the active pixels matches the resolution you're trying to set.

1280x1440 @ 60 Hz doesn't require dual-link DVI, so it wouldn't be affected by this problem.

What did you try with CRU? 2560x1440 should have already been there if the monitor was reporting itself correctly.

The problem is the Radeon 9200 is too old and not officially supported in Windows 7. Supposedly there are ways to get it working, but some of the old links are broken.

You might be able to get it working with this driver:
