Unhappy To all the 1900x1200 & 1680x1050 LCD monitor owners...

Hi,

This is my 3rd day of researching all over the net for what I'd originally thought was a simple task. I'm so confused as a result and I'm now resorting to asking the experts here. I'd just purchased a new lcd, Acer 2423wdr, and I need an appropriate video card to output 1920x1200. This is what I've gathered thus far:

- some FX5xxx series work OK in this res, but I'm unclear as to how movies play. I read from a few posters that these series have subpar TMDS chips.

- many had success with their 6600GT cards in this res but a few had problems. Someone mentioned that not all 6600GT cards are created equal & recommends leaning toward brands with dual dvi connectors. Could anyone verify this claim? I hear PNY 6600GT can easily output this res via dvi but this model has a fan and I'd really like to have a fanless model, such as the Gigabyte NX66T, which is way out of my price range. Do 6600 models use the same linux driver as 6600GT?

I'm not a gamer. I just need smooth xvid/divx/dvd playback. I don't consider myself a videophile. I've been more than satisfied with the video performance of my old 19" lcd monitor (1280x1024 via analog) from my onboard video (SiS 760, I believe).

What is the minimal graphics card that can output 1920x1200 reliably under linux with acceptable video performance via analog? How about via DVI? I can't help but feel that the 6600GT would be overkill & MX4000 would not be up to the task for my situation. I've been leaning towards the 6 & the 7 Geforce series (PCIe interface, fanless preferred). Any recommendations from you gurus would be greatly appreciated, especially from those of you who already own 1920x1200 native res lcd monitors.

One last favor, I promise: I also need to find a card for my girlfriend who had just purchased an Acer 22" lcd (1680x1050). I haven't had time to research anything yet for her since I've been so consumed with researching cards for my new lcd. If anyone could recommend a minimal AGP card that can output 1680x1050 reliably via analog and/or dvi under linux, I'd really appreciate it. Her needs are like mine: smooth video playback only; no gaming whatsoever.

Thanks for reading my long post,
Sean

as far as i know you should be able to push out a 1920x1200 pixels by an analog connection with about any card out there... even an old MX4000 should be up to the task...
But of course if you want digital output (and i assure you, you do not need to be a videophile to appreciate the quality of dvi) you will need a card that supports dual link dvi. Normal dvi specs only allow a maximum resultion up to 1280x1024. But with a dual link dvi connector you can push that up easily all the way to a 30" lcd apple monitor...
Current dual link dvi cards are : eg: http://www.asus.com.tw/products4.asp...90&modelmenu=1

but if you are happy with just normal analog playback even this 7300 will do...
http://www.asus.com.tw/products4.asp...l1=2&l2=6&l3=0

but i'd recommend the 7600 ... you should be able to find it for about 120 $...
I do recommend to get some decent air circulation in your computer case if you want to go with a fanless videocard... (big fans, low rpm ==> low noise)

The real question is if the linux drivers are up to these specs... but afaik it should not be a problem.

gr,S.


and another one : http://www.xfxforce.com/web/product/...ationId=198678

pny is a workstation graphics card producer in the first place and that is why almost all their cards support dual link dvi ... the problem is that they do not list the specs of the card in a decent way so there is no way to tell if the card will truely support dual dvi... I'd recommend that you stick to brands with decent online listing... if you're not sure just don't buy their stuff

Many 1920x1200 displays are just single-link DVI. They use a 155MHz clock instead of 135MHz.
While this means that many FX5200 cards cannot drive such a monitor because they are limited to 135MHz pixelclock, it does not mean that you need dual-link DVI.

I have a 6600GT card with single-link DVI and my 1920x1200 Dell 2505FPW monitor works OK on it.
Like bugmeplz, I want to use the card mainly for video. I have a HD LCD TV connected as a second monitor (not as a TV).

I too would be interested in a card that emphasizes on video instead of gaming. I would like to have hardware-assisted MPEG decoding and de-interlacing working at 1920x1080, where ideally the system just has to push the MPEG stream to the card and everything else happens on the card. Like in a DVB receiver. That would likely end all the frame-skip trouble that happens when the main CPU is involved in video decoding.
What I don't need is superfast pixel shaders used in 3D gaming. I rarely ever run a game.
What I would prefer is a fanless card that does not use so much power.

Right now, it seems that faster cards that can drive monitors at somewhat higher resolution invariably are positioned in the gaming market. Video capabilities are advertised as well, but part of them are in the Windows drivers and not available on Linux. Indeed, the 6600GT probably is overkill for video, but on the other hand it (together with its Linux driver) lacks some capabilities that would be very useful.

El_Angelo, thanks for all the suggestions & links. You've got me curious again about how dvi may possibly look better than analog so I'm finally going to test for any noticeable differences between the two for myself.

pe1chl - Ya, I wish such a card-&-linux-driver exists for us non-gamer-only-video-on-linux users. I'd justify paying $$ for it. What make is your 6600GT? Does it have dual dvi connectors?

I just bought a 6200 for my gf's lcd so I'll test how my movies look within xine for both 1680x1050 & 1920x1200 via dvi. Then I'll decide if I need to spend the extra cash for a better, more $ card.

My 6600GT is from XFX. It has 2 DVI connectors. I think single-link.
(but I am not sure. my monitor is a Dell 2405FPW and it is single-link, maybe the card would turn out to be dual-link when I connected another monitor)

pe1chl, El_Angelo,
Thanks for providing your cards' info. You both helped me a lot in my search.

sidSAS,
Thanks for the configuration details - the info will really help me out once my ordered 6200 arrives soon. I'm really impressed by the Acer 22". I hope you're enjoying it. Do you have it connected to your card's vga or dvi connector? Do dvd and xvid/divx movies play smoothly on it within xine?

You do not need dual-link DVI to run 1920x1200 as long as you don't want too high refresh rates.

I am posting this from a Dell2405 1920x1200 which used the following entry in both a 5900XT and a 6200 something. Works like a charm:

Modeline "1920x1200dell3" 154.128 1920 1968 2000 2080 1200 1203 1209 1235 -hsync -vsync

This one exceeds the capabilities of my 6200:
Modeline "1920x1200dell2" 161.75 1920 2020 2052 2184 1200 1202 1208 1235 -hsync -vsync


Also, there are 6600GT cards that do dual-link, among other things at least the newer eVGA I have. It is clearly marked as "30" Apple Cinema display ready" or something like that on newegg.

I can get my FX5200 PCI card (it's fanless, I don't want to take crap about my choice) to support 1920x1200 (as advertised), but the nVidia drivers cap the dot clock to make that impossible on DVI. I used to force it with some interlace trickery, but a driver upgrade caused that modeline to start being rejected. Analogue output at that resolution is OK, but slightly noisy on the pathological case of the default X11 backdrop. I generally don't have a problem with it.

I also used to have problems with display glitches when using xvideo acceleration at that resolution, on both analogue and digital. The solution, as it turned out, was to enable twinview (not proper dualhead, but the nVidia kludge) and run another display that I never use on the TV-out port. Simply having that enabled makes the xvideo problems go away. It's counter-intuitive, because it was clearly a bandwidth problem that caused the interference, and adding another display should increase the load. It just works, though, and I don't care to know why.

Martin, Gumboot,
Thanks for your input. It's great to hear that other Nvidia series can drive these high rez monitors.

Anyone reading this thread who just needs a fanless Nvidia card to drive these resolutions via dvi in linux with acceptable divx/xvid/dvd performance, I recommend the 6200 with the latest driver from Nvidia. The install-script configured my xorg.conf automatically and I didn't even need to insert any modeline numbers. Not bad for a $40 card. I don't think this card from PNY can be used for a dual-monitor setup though.

Now I'm looking for my own card in PCIe so I just need to decide between a $50 6200TC (turbocache) or a $90 7300GT, both from Gigabyte. I guess the 6200TC will be similar to the 6200 in terms of the ease of linux install and video performance. I realize that the 7300GT is a much better card but I don't think I'd notice any difference when the 6200 can meet the needs of a basic video viewer and a non-gamer. The 6200TC seems to be the right card for me unless someone convines me otherwise.
