Windows 10: GPU Advice needed
GPU Advice needed
My dual 27" full HD (1980x1200) Dell monitors are now ten years old. They still work OK, but I'm thinking it's time to replace them. Can anybody tell me what kind of GPU(s) and cables I'll need to replace them with a pair of 34" monitors instead? (Find them online at Dell UltraSharp 34 Curved Ultrawide Monitor - U3415W | Dell) Can I drive both from a single graphics card (each is 3440x1440 in resolution)? Will a single graphics card support two dual cables, one for each monitor? Should I use HDMI or DisplayPort as my link-up? I've never had to think about driving so many pixels before, and I'm not sure I understand all the ins and outs. Perhaps I do need two GPUs. If so, can I run them independently without having to use SLI?
Please help me find my way into the world of dual high-res monitors, and the graphics card(s) that drive them.
Thanks in advance for your information and suggestions.
I was just curiously reading and would ask about "two dual cables". Isn't that kinda redundant? There are dual/Y cables available for running 2 monitors from the same socket on the video adapter. Or maybe I'm missing something? If I were building a computer for using dual monitors I'd get a video card with 2 DVI ports and use DVI cables. The bigger monitors seem to have more choices, early this year I was given a 27" ACER monitor that has 4 inputs, DisplayPort, VGA, DVI and HDMI [lady was moving a couple thousand miles away and didn't want to ship it].
Thanks Berton: a single-link DVI connector can handle 1920x1200, so a dual-link is 2560x1600. These monitors are 3440x1440 so even a single dual-link DVI cable won't cut it for even one of them. Now we're making progress, because I now understand that I must use either HDMI or DisplayPort. According to this story I just found: http://www.digitaltrends.com/buying-...ayport-vs-vga/, HDMI 2.0 can handle up to 3820x2160 so one each HDMI should work. Even more progress? DisplayPort is just about the same: 3840x2160. So it looks like I can go with a single HDMI 2.0 or DisplayPort cable per monitor. That's what I needed to know, so thanks a bunch!
An Nvidia 1080 graphics card offers max resolution of 7680x4320@60Hz. Let's do some math: the Dells are 3440x2160 so if we double the width, we get 6880. Height stays the same, so yep, I can drive both of them with a relatively new technology GPU. Cool!
PS: most configurations of the 1080 have 1 HDMI 2.0b, 1 dual-link DVI and 3 DisplayPort connectors on the back. Looks like I'd need to use 2xDisplayPort for the 2 monitors to get the best overall experience. According to what I read on the Nvidia site, DisplayPort will even ferry audio, so I can use the built-in speakers on those monitors if I am so inclined.
Yes, displayport is the way to go
I have a single UHD (3840X2160) monitor. I use a DisplayPort connection because, at the time I bought the monitor, it was the only standard that supported UHD at 60 Hz.
HDMI 2.0 added UHD support at 60 Hz. HDMI 2.0a adds HDR (10 bits per color). I'm curious about HDMI 2.0b claims: in the TV universe, I think that's for dynamic HDR metadata. As far as I know, no monitors exist that use that.
I think I'd stay with DP if only because it's specific to monitors (rather than TVs). My only dislike for DP is that the connections don't seem all that robust. I guess I miss the VGA and DVI connectors with tie-down screws.
With your i6700 CPu & GTX 750 Ti the bottlenecker web site says you GPU is 50% too weak for your CPU, when you buy a new GPU use the chart guide to keep the bottleneck in the green percentage for best efficiency of your system.
The theory has suggested a GTX 780

Hi Ed, I have a single Dell 34" monitor and I use the display port connector. I'm very satisfied with it. I cannot imagine having two of these on my desktop. I think that you should be able to daisy chain two of the monitors together with display port. You'll definite need to be sure that you graphics card can pump out enough pixels for two of these monsters. There is an well known issue with the sound setup but that can be addressed with the setup on the monitor control panel.
Thanks to all for their suggestions so far. I was planning to try daisy chaining, so thanks Bob for that affirmation.
Hi Ed, it's me again !
I just did a re-think for your system & thought of the following:
Use 2 X 1050Ti's with your i7 6700(K)??? or is it a different model
These will work great with your setup, you will get the resolution you want & you will save money ?
Good suggestion RB: I'm not a gamer anyway, so high performance is not an issue for me. I've never felt hampered by my 750Ti with the twin Dell 2707WFPs I've got right now. Thanks!
He is what I have, three computer's on home network,they are hardwired to a Linksys Router. I can share files between them without problems. Have no cable where I live,use a Verizon Hotspot from my phone for internet. I use a Netgear WNDA3100...
I am running Windows 10. I currently attach a hdmi cable from laptop to tv. Is it possible to stream one thing from laptop onto tv screen and simultaneously surf the net using laptop monitor?
Since I'm going to install a new SSD in my lappy, I want to increase the memory also.
I want to install 16GB, it has two slots. One has 8GB in it now.
I looked on Crucial and there are four choices for 16GB kits.
Which would be the best...
Hi guys please have paitence with me on the installation of Win10 on the go environment!
I've been reading alot and have not yet put it into practice yet.
Waiting for a USB3.0 Scandisk Extreme 32GB to be delivered I want to use on win10.
i need to backup my complete pc as i am going to install the windows 10 preview. the trouble is that i havent got a usb hard drive. so how do i do this and what software do i use to do this?
