This is a two-parter, and I have no idea if they're related or not.

I recently built this computer (about a month old). It's running an

GPU: NVIDIA GeForce GTX 650 Ti
CPU: AMD FX 6300
RAM: 8 Gb (G.Skill Ripjaws X (9-9-9-24))
OS: Windows 7 Ult 64 bit
Monitors: 1x Acer x213H @ 1920X1080 (DVI), 1x Dell IN1910N @ 1366X766 (VGA)

Question 1): Ever since I first turned on the machine, before having updated any drivers, and before running a multi-monitor setup, I've noticed faint, flickering horizontal lines that slowly move from the bottom of the display to the top. After making sure everything was updated to the latest drivers, and making sure all the settings were correct (AFAIK, anyway), it's still there.

It's completely unnoticeable on lighter backgrounds, only when on a dark backdrop, like my DT wallpaper. It has become less noticeable, but has been replaced with more of a solid flicker, as opposed to lines moving up the display. The monitor's max refresh rate is 60 Hz, so that's what everything is set to, across the board.

This is all only on the Acer monitor; the Dell doesn't have any of these issues, and never has.

Question 2): I notice, in some games, some significant horizontal tearing. HL2, Mirror's Edge, Skyrim and Oblivion, War Thunder, Rust, etc. all display this. I've found that turning on VSync in-game solves this, but is there any sort of a more elegant workaround? If not, oh well.

Again, AFAIK, this is only an issue on the Acer, not the Dell.

Thanks for any help and insight.

1 question - it sounds like your monitor is running at 59 Hz. I notice the same thing when windows is in the loading screen (even though for just a second). Check your nVidia control panel again when connected to that monitor.

2 question - that is perfectly normal. And you don't have any workarounds without buying new hardware.

Cheers.

As far as I can tell, every place where I can set settings, it's set to 60 Hz ref. rate. In NVIDIA control panel, in the Asus GPU Tweak, in DisplayFusion's settings, and even in Windows' settings, they're all set to 60 Hz.

Thanks for your quick response. Any other ideas?

What cable are you using? VGA? Or DVI or HDMI?

VGA on the Dell, DVI-D on the Acer.

What brand is the 650 TI? Have you tried plugging the DVI in other port (if your card has one)? Have you plugged the Acer to another machine? Did you try another cable?

It's NVIDIA. I have not tried another port, I think that's something worth trying. It was originally plugged into the VGA port, as when I bought it, it only had a VGA cable with it. I've since bought a DVI-D cable. I'll post back once I've tried it in another port.

Your video card brand should be something like Asus, Gigabyte, MSI, EVGA, etc. nVidia is the designer of the board, but it is manufactured by someone else. Who is the manufacturer? My 650 TI is manufactured by Asus for example.

My bad. Mine's also manufactured by Asus, the same folks who made my mobo.

I tried swapping out the output port, to no avail (also took the opportunity to clean out the case, as it'd been a couple weeks and I live with animals who shed).

Over time (and I have no idea when this might've happened, could very well have been when I switched from VGA to DVI input) the flicker has changed from a series of faint lines moving up the display to a faint pulsing. I tried to catch a video of it, but my iPhone was just getting a bad moire pattern, and wouldn't pick up on the pulse.

Dunno if any of that helps. Thanks again for making the attempt!
