x3 Ultrawide and 4K TV

johnnysneds · Nov 30, 2016

Hi All,

I am putting together a PC for trading, its probably a bit over the top but here we go.

I will go with x3 LG ultra wide monitors wall mounted (LG 34UC98-W). The resolution for each monitor is 3440x1440. I would also like to mount an additional 55" OLED Curved 4K Ultra TV above these.

My question is will my build be able to handle this display output. I am not interested in gaming however I am sure it will be quite capable of this if required. I have chosen a GTX1080 graphics card (Zotac GeForce GTX1080 AMP Extreme 8GB GDDR5X (ZT-P10800B-10P)). Is this card going to be sufficient or am I looking at two GTX's in Sli.

My build components are as below:

Case - Corsair Carbide Series Air 740 High Airflow ATX Cube Case Black (CC-9011096-WW)
Motherboard - Asus ROG MAXIMUS VIII EXTREME/ASSEMBLY / Z170
Processor - Intel Core i7-6700K Skylake Processor (8M Cache, up to 4.20 GHz) (BX80662I76700K)
Graphics Card - Zotac GeForce GTX1080 AMP Extreme 8GB GDDR5X (ZT-P10800B-10P)
Hard Drive - Samsung 500GB 2.5" SSD 850 Evo Series (MZ-75E500BW)
Cooling System - Corsair Hydro H110i v2 Extreme Performance All-in-One Liquid Cooler (CW-9060026-WW)
Monitors - LG 34UC98-W (x3)
Memory - Corsair Vengeance LED 32GB 3200MHz DDR4 DIMM CL16 (2x16GB) Red LED (CMU32GX4M2C3200C16R) x2 (total of 64Gb)
Power Supply - Corsair RMi Series RM1000i 1000 Watt 80 PLUS Gold CP-9020084-NA

the ultrawides will hopefully look like something like this-

If you're not gaming then that build with 1 1080 will be perfectly adequate with Nvidia Surround. You're planning on using the 3 LG monitors over Displayport and the TV over HDMI 2.0a right? If you want to game with the 3 ultrawide monitors at high settings you'll want to pick up a second graphics card, but if you're ok with medium settings and less AA you can get away with just 1.

There is only two display outputs from the graphics card so one of the LG ultrawides will have to be HDMI.

I had a reply from EVGA (see below). The card is more than adequate for the x3 LG's, however the concern I have is adding the 4K above.

Hi John,

Thanks for your interest in EVGA products!

The maximum surround resolution supported is 11520x2160. Your monitor configuration will be fine.

Please contact us with any further questions.

EVGA Support

Looks like 3 displayports to me

You could buy a lower end GPU for the 4K HDTV as long as your not gaming on it and run the others on the 1080.

johnnysneds · Nov 30, 2016

ah ok yes you are correct. I notice that it says 4 monitor support, so if i add up my total surround resolution it will be: Just the LG's - 10,320 x 1440 then the 4K TV - 3,840 x 2,160. The cards max surround resolution is 11,520 x 2160. So thats 23,155,200 pixels (my setup) versus the cards max 24,883,200. So i am just inside this using basic arithmetic but I'm not sure this is how it works.

chemmajorp53 · Nov 30, 2016

I honestly haven't heard of anyone doing this setup (it's a **** ton of pixels) so I'm not actually sure if that's a pixel hard limit or not. Like Wildcard said though, worst case scenario if it doesn't end up working, you can just throw a GTX 1050 in or something and run the 4k TV off that. There shouldn't be any situation that you find yourself having to spend more than $100 or so extra to get it all working.

johnnysneds · Nov 30, 2016

ok thanks, i wasn't aware you could put different types of graphics cards in separately. I wrongly thought they had to be the same but i take it this is for Sli. Is there any downsides to using tow different cards, drivers, dragging the rest of the system down etc?

chemmajorp53 · Nov 30, 2016

I wouldn't put an AMD and an Nvidia card in the same system, but any two cards that use the same driver should be perfectly fine.

johnnysneds · Dec 1, 2016

So it seems Zotac are pretty confident their card will handle this:

Hi Sir,

m8 have u tried 4k 40inch. its best ive used for trading

Doggie314 · Dec 22, 2016

johnnysneds :

my own research has me steering away from that card due to fan inconsistency

johnnysneds · Dec 22, 2016

So far so good. I have the 65" mounted above and it's great. No fan issues with the zotac, runs cool.

Doggie314 · Dec 22, 2016

so the tv is a 4k tv at 65 inches? can you tell me what that runs like with the 1080? what fps do you get generally?
Also, when i bought my 4k mons a year or so back, i did so as (i think) 4k tv could not (at the cheapo price point i was working at) do 60 fps/hz games etc, but the bdm4065 uc could. Has this changed now and is using a new 4k tv jsut as viasble as my Philips bdm4065uc setup?

johnnysneds · Dec 22, 2016

Yes it's 4K OLED works great for my needs. Very crisp and detailed picture. I'm not interested in fps.

Doggie314 · Dec 22, 2016

you use it to trade/?

Doggie314 · Feb 8, 2017

HI there, can you update me on the oled performance as a pc monitor? has there been any image retention of windows icons etc? currently weighing up a B or c oled from lg against samsung led ks7000

johnnysneds · Feb 14, 2017

Doggie314 :

Only issue I have with the OLED is there is a noticeable delay with the mouse movement. I adjusted the screen for gaming and it improved slightly. I don't use it for gaming so it is a minor issue for me.
