Anyone who has a 6200 can confirm it outputs 1920x1200 over DVI without issues? Thanks.

I would assume so? Should say right on the box, if not, in the manual. Unless there's some known issue I don't see why it wouldn't. =)

be careful about what's claimed for max res on the specs. once read a post by an angry guy because the max spec claimed for his card was for vga only, not for dvi. just ask around.

The only 6200 board manufacturer I have found that even provides specs on the DVI port is Club3D. They claim a curious 1900x1200 resolution (not 1920x1200). Having read the articles at Extremetech about DVI problems I thought I asked here for reallife experiences.

Unless the card vendor really fatfingered something it does 2048x1538.

Only the analog VGA port will do 2048x1536. Not the DVI port.

The DVI port with do 2048x1536.

Mine does, anyway :)

Incorrect, the DVi port can do a maximum of 1600x1200 and in some cases 1920x1200 with reduced blanking (monitor support required). However, with a DVI to VGA adaptor it can output the same resolutions as a normal vga port.

DVI-I ports are spec'd to run 1600x1200 @ 60Hz Digital resolution and 2048x1536 @ 85Hz Analog resolution.

Most NVIDIA cards if made to NVIDIA Spec (BOM & AVL), have at most times been able to display 1920x1200 @ 60Hz Digital. This can be achieved by simply setting this as a custom resolution in the driver control panel. In essence you are overclocking the single link TMDS.

:D

My FX5200 won't output 1920x1200 over DVI in Windows XP. When I try to add the custum 1920x1200 resolution, it is rejected. 1920x1200 is possible in Linux and works mostly well, except when using video overlay to play movies which results in ugly tearing.

That is why I want to upgrade to a newer card, possibly without fan and since I don't play games I had hoped to settle for a 6200. All I need is a confirmation from some kind 6200 user that 1920x1200 DVI output works without problems :)

Since most board manufacturers don't spec their DVI outputs, it would be a problem to return the card when 1920x1200 proves not to work after purchase.

My 5900XT does 1920x1200 just fine, in DVI with a Dell 2405FPW.

I play DVDs and other videos all day (have to go through TS:Voyager before I re-marry :)) and there are no issues with tearing, stuttering or any other synchronization problems.

Now, one problem is that the 5900XT can obviously not put the XVideo controls (for brightness etc.) on the DVI port, even if you make that one the first screen. However, I observe no picture quality problems from that either. I just have to use the X11 controls. I have to try my 6800 Ultra to see whether that one can put the controls on one DVI port.

Koef (is that name based on the Diesellok?), in Linux we need a custom modelines for 1920x1200 to keep the overall clock below 165 MHz. The default figured by the binary driver NVidia provides does not work (the one from the OpenSource drivers) works. You need something simialar in Windoze.

Hm, what the above said may be the case. However, what is the monitor your trying to use. Old ones have some funky edid (or whatever its called) crap and dont work. Espically sun ones.

I use the modeline posted by alex31 (http://www.nvnews.net/vbulletin/showpost.php?p=624263&postcount=17) and it works really well except with video overlay (tearing).

You need something simialar in Windoze.
I don't know how to do that. The Nvidia drivers offer "custom resolutions" to be entered, but when I try to add 1920x1200 it is rejected for my FX5200. I also tried powerstrip, no joy.

I have a Dell 2405FPW, and I have my config set to ignore EDID data.

The GeForce FX fan is a joke. I replaced it with a passive cooler, Aerocool VM-101. Works great now at low temperatures but before you jump on it there was some bitchingwhiningcomplaining involved. I'd rather get the Zalman.

My modelines is
Modeline "1920x1200dell2" 161.75 1920 2020 2052 2184 1200 1202 1208 1235 -hsync -vsync

This also works:
Modeline "1920x1200dell3" 154.128 1920 1968 2000 2080 1200 1203 1209 1235 -hsync -vsync

I don't know how to do this stuff in Windoze. The key factor here is not to supply the resolution but to keep the overall clockspeed below 165 MHz.

I have a 5200 but I didn't try it with the widescreen display yet. I don't think I can get that done before I leave for vacation tomorrow, I would certainly have liked to help with that. It is possible that the 5200 DVI is not as capable as the 5900XT one.

I just went ahead and got a MSI NX6200AX. Everything is working fine now. 1920x1200 over DVI and no more tearing with video overlay. As an added bonus the 6200's heatsink stays much cooler than the FX5200's. Thanks all for your support!
