#DELL C1765 CFW WINDOWS#
I eventually tried taking out the '/3GB' switch and its now working very nicely (apart from windows programs can only use 2GB now rather than 3GB.)
#DELL C1765 CFW DRIVER#
Tried all sorts of different settings (BIOS and windows), forceware driver versions, etc, but nothing worked. With that switch present 9 times out of 10 when I booted the machine the nvidia driver didin't load and I got a bog standard VGA adapter with 1280x1024 res! Took a lot of fiddling round to get it to work though, due to me having 3GB of RAM, and using the '/3GB' switch in boot.ini. Got a new XFX GeForce 6800GT, two DVI outputs (single link on each output) I'd like the Asus but the GPU and memory clock speeds aren't very fast (325 & 700) and its only got single DVI
If I ever get a second TFT monitor I don't want to have to buy another card to drive it using DVI!ĭecent 6800GT card. The new 7xxx GeForce cards supposedly do dual-link on a single DVI socket too.Īnyway, as far as I'm concerned I'm just after a decent 6800GT card, preferably with dual DVI sockets on it. Just using the transmitter chip on a GFX card does help though, the Asus LE9999 6800GE uses this enhanced chip, and they think that the Asus LE9999 6800GT 256MB card does (but not the older 128MB version, just the newer 256MB card), the 6800GE definitely works with the Apple 30" monitor (but one user has reported minor problems). If a transmitter and receiver pair of these are used it'd be perfectly possible to use with absolutely no problem, but no ones heard of the receiver chip being used in any monitors yet. To confuse matters further Silicon Image, one of the companies that makes the chips that encode the DVI link signal, have produced a new version of their chip that raised the 165MHz limit upto 225MHz.
Some 6800 cards have two DVI sockets, each with a single link in them.Ī very few have two DVI sockets, one has a single link, the other has a dual-link, and only those are able to drive monitors like the Apple 30" monster. Normal 6800 cards have one socket, which has a single DVI link in it. By tweeking the timing settings this can be pushed upto but the DVI chips operating absolutely flat out at this rate. So if the manufacturer wanted they could give you two physical sockets, with two DVI links in each one, allowing you to drive two very high res monitors.Įach link can drive upto 165MHz pixel clock, or approx max res. Each DVI socket can have one or two 'links' in it. I've been reading up a lot about high res and GeForce 6800 cards and DVI monitors. Could be a faulty card of course but too late now, its not something I would have ever found out had I not got this nice DVI monitor. I'm just assuming its cause its an old very card, and maybe a cheap brand (Inno3D) so when its operating at very close to its maximum specs its just pushed too far. The card I have automatically sets up the reduced blanking so the signal is within the 165MHz bandwidth limit, but it still has problems.
I'm going to have a play with powerstrip and see if that can improve things, but there's so many timing settings it could take me ages :-(Īnyone close by got a GeForce (or ATI) card with DVI output I could borrow for half a day or so? I'm aware that 1920x1200 is actually beyond the spec of a single DVI-D link, and they need to tweek the timing settings, etc, to fit the extra res in, but could this be down to a cheapo graphics card? Poor quality DVI cable? Monitor problem? Graphics card problem? The effect seems to be triggered when there's a solid horizontal line that is a different colour to the rest of the back ground, to the right of this line its as if the pixel clock looses lock and the line is shifting right/left fast.
#DELL C1765 CFW TV#
The tearing sparkles all the time too, like TV static, weather you're doing nothing or not.Īnother way this problem shows is when you have slight changes in colour in an image, say you've got the standard Microsoft "TellyTubbies" hill wallpaper set, open a window and move it around and you can see bright cyan 'lines' coming and going and sparkling in the sky and clouds of the wallpaper. If you move another dialog box around ontop of the first one the "tearing" moves round. On say a dark grey background with a dialog box, the right (and sometimes left) sides of the dialog box will slightly "tear" by maybe 5 pixels. *But* there's a really annoying problem, which is hard to describe.
#DELL C1765 CFW PC#
Graphics card in the PC is an Inno3D GeForce FX 5900 XT which has VGA and DVI outputs.Ĭonnecting with VGA and there's no problems, everything works great, apart from text isn't as sharp/clean as DVI.Ĭonnecting with DVI and there's a very nice improvement in the quality. I've just got one of Dells 24" TFT monitors, 1920x1200 res.
