LCD Screen buying advises

Juergen-BY

Hi Guys,

I`m on the way to rebuild my Racing PC. Therefore i have also planed to buy a new LCD Screen. At the moment i`m using a 27" Ilyama Screen (PLB2712HDS) with 1920x1080 px. The point why i`m thinking about to buy a new one, is the resolution. I believe with a better resolution (3840x2160) i could see ingame the mirror on the right side too? Is that something complete wrong or not? Just to telll you, Triple isn`t possible because of missing space. Budget could be around 500-600 EUR.

This is the hardware i`m using:

Core i7-5820K, Asus RAMPAGE V EXTREME, EVGA GTX 980 Superclocked, PS Dark Power Pro 10 1000W, RAM 16 GB DDR4-2133, 2 Samsung SDD`s, Win8Pro 64Bit

At the moment i`m looking for a ProLite B2888UHSU-B1 but it would be nice to get some advises & informations. TN Panel is fine for me, i`m sitting in front of the screen ;-)
 
The resolution you quoted is still 16.9 but 4k.
You will not see the mirrors any better than you do now. 4k is very hard to run also, you would need at least another 980
 
At the moment i`m running a 27" with 1920x1080 px. If i replace the Screen with a LCD with 3840x2160 resolution, i got the double resolution in the width, right? If i have the double resolution, there are double px to show of the games content, right? If so, why i can`t see the mirrors ont the right side? Please help ;-)

Well the resolution in x and y direction is going to be doubled and therefore the aspect ratio is the same 16:9. If you trying to get a wider screen to see more from the side mirrors you either need to go to a multiple monitor setup or 21:9.

This in fact would increase the x resolution relativ to the y resolution.

Beeing x the width of the screen and y the heightšŸ˜‰

Both screens are from LG (34" monitors). A quick comparison on the LG website shows that the 34UM95 has higher resolution, higher color depth (more colors) and higher dynamic contrast.

If the price is o.k and your graphics card can do the high resolution 3.440 x 1.440 @ 60 Hz with at least 60 FPS i would go for the 34UM95.

If you buy one of them It would be great if you provide your first hand experience.

Thats the problem, i`m afraid my graphics card (GTX980) can`t handle the 4k with proper (60+) FPS...

@oHOWEo: did you tried some other e.g. GT Cars? Could you see the right hand mirror?
 
I could definitely see out of one side window with 35ish fov. Much better than my 16:10 monitor. Im having issues with the monitor turning on with the pc, sometimes it's fine other it say no signal. Really annoying
 
By any chance, did you installed the latest Nvidia Update (344.80)?

You could use the DSR feature in the Nvidia Control Panel to gauge how your card can handle higher resolutions like 4K. I imagine your 980 should handle the 2560x1080 monitor just fine but for the 3440x1440 the DSR scalers fall inbetween, 2.25x not being quite enough and 3.00x being too many.

As for the view these 21:9 monitors give you could use windowed mode and a custom resolution in your 'config.ini' that fits your current monitor, say 1680x720. Obviously it's a bit low-res but will give you an idea of how much extra you could see.

+1

Thought this was made obvious in discussion we had, although no one wanted to carry one with it so maybe we had, there would be more references about the forum to see.


Really 4K I have seen tested in any game do the testers say it is great, maybe good or okay and half their games probably average to unplayable .

And the thing is console ports and shooters are usually smoother to play at lower fps.

Like say at 4K in a shooter you could spin a round a bit slower to limit stutter and stuff.
............. but in a sim you can't just slow down or turn the wheel slower. :)


The thing that bugs me about Hi end gear / monitors is what is the use if you don't run capped at 120Hz or 144Hz with inspector hex edit ( or whatever) with lightboost gsync .......and all that stuff and the best latency ?


We are talking about rF2 ain't we not BF4. ;)

I would think 5GHz extreme processor and dual or triple GTX980Ti would be the "4K order of the day"

Even then you would need to run 3D to get good scaling ........probably.

lG 34UM95 it appears from other experience that the supplied display port cable might not be up to snuff, Im hoping this is whats causing the wake issue. I've ordered a display port certified cable, finger's crossed. Really want to keep this monitor. It's like having a really good looking girlfriend, you let a lot of s*it slide lol

At the moment I`m using a DVI Cable, but i want to change this to DP. Wich cable i should buy? There are so many different Cables, with very big differents pricewise. It goes from 7 EUR up to 170 EUR....Any advises?
 
Ive been messing with the display port cable all day, In the end I thought **** it and connected via HDMI, well guess what.... full native resolution at 60hz 32 bit colour.... what the hell! All problems solved!!!!!
 
Just go to the displayport site and get an authorized one. They are on Amazon, I bought 3 and have used them on triple screens with all 3 monitors @ 144 Hz (AMD 7970 Matrix) and Nvidia triples @ 144 Hz and 120 Hz 3D.

Are you sure you're getting native resolution (3440x1440) @ 60Hz via HDMI? That shouldn't be possible as HDMI doesn't have the required bandwidth. Could it be that you have DSR enabled and the 3440x1440 is actually being rendered at lower resolution? That's the only way I can think you could have it set up for 3440x1440 via HDMI.
 
It works with hdmi 2.0 it has enough bandwidth for 4k at 60 hz. All I can think of is when the monitor was first introduced hdmi 2.0 wasn't commonplace

I had one on order spin until hdmi saved the day
 
I'm going to check it's not dsr wizardry, techade has planted a seed of doubt, pretty sure its not though. Strange thing is I have been told the monitor hdmi port is only 1.4a also the hdmi lead is a good 3 years old, not sure I buy the theory that the cables themselves differ unless there is a pin change.

According to the manual HDMI supports up to 3440x1440 @ 50Hz but not at 60Hz.

So I was kinda right (3440x1440 @ 60Hz not available via HDMI), though I was also kinda wrong because I didn't expect it to support anything over 1080p60 via HDMI.

It looks like the improved HDMI specs are making their way into consumer items at last! :)
 
Ok so I'm still confused, I have the monitors driver installed and when I choose "native resolution 3440x1440 it does only give me the option for 50hz or 60hz with 16bit colour.
I have a custom resolution that is 3440x1440 60hz and 32bit colour, DSR isn't selected in the Nvidia controll panel, am I getting what I think I am?

Interesting, did you set up a custom resolution for 3440x1440@60Hz?
 
If HDMI 1.4 runs 4k at 30hz, that makes 3840 * 2160 = 8,294,400 pixels per frame * 30hz refresh rate = 248,832,000 pixel refreshes per second at maximum bandwidth

The LG screen is 3440 x 1440 = 4,953,600 pixels per frame

248,832,000 pixel refreshes per second @ 4k / 4,953,600 pixels on the LG = 50.23hz maximum refresh rate

According to the bandwidth spec it should be able to handle 50hz then.

According to the last post there, you seem to be really pushing current HDMI v1.4 bandwidth. Surprised you're getting away with it.

Do you have a real short, and real thick guage HDMI cable? Maybe this is what's letting you achieve so much bandwidth over the standard rating, since the ratings are probably worst-case scenario minimums.
 
The manual also suggests that 3440x1440 @ 50Hz is the max via HDMI.

Notice that in oHOWEo's shots 60Hz is listed as a Custom resolution. If it were a standard resolution the monitor reported via EDID then I don't think it would be listed as a custom resolution. Unfortunately I don't have one to test it myself, wish I did! :)
 
Yup, seems about right since 4k (3840x2160) @ 30Hz is about the same as 3440x1440 @ 50Hz. I have a feeling that the HDMI cable of his is just allowing the bandwidth through since the specs of HDMI standards are just bare minimum specs, there's nothing disallowing the data/bandwidth to flow through higher than the "standard-rated" HDMI v1.3/v1.4 advertised specs of 10.2 Gbps (8.16 Gbps video) as long as the particular cable itself happens to be able to handle it...however once passed those specs it's obviously not a guarantee and if problems come about then the user can't blame the cable as it's being run above spec.

Displayport v1.2 offers double the bandwidth of HDMI v1.3/v1.4, and even more than HDMI's new v2.0 (really, HDMI? Sad). DP v1.2 is therefore easily capable of fully powering 1920x1080 @ 144Hz which is about 20% more "intense" than 3440 x 1440 @ 50Hz ("intensity" calculated from total pixels * refresh rate). Furthermore, DP v1.3 just came out (Sept. 2014) and offers even more bandwidth (8K, anyone?).

Interface
Bandwidth
Video Data Rate
DisplayPort 1.3
32.4 Gbps
25.92 Gbps
DisplayPort 1.2
21.6 Gbps
17.29 Gbps
HDMI 2.0
18.0 Gbps
14.40 Gbps
DisplayPort 1.1
10.8 Gbps
 8.64 Gbps
HDMI 1.4 / 1.3
10.2 Gbps
 8.16 Gbps

Getting a little off-topic, lol :) Bottom line, oHOWEo, you may happen to have a good quality HDMI cable that allows you to pass beyond the standard-advertised bandwidth specs of HDMI v1.4/v1.3 without issues (screen blanking out, sparkles, etc.). If you want to play it safe, though, rest assured you have options.

One thing to note is hdmi audio is currently disabled, using a dedicated sound card, maybe that's helped on the bandwidth. Having said that I did test the monitor speakers last night via hdmi.
 
Enable vsync, and see if the in-game framerate is at 60 fps (and perfectly smooth), this will surely be all the proof you need to make sure everything is working just fine at true 60 Hz.
 
Its a 2 meter cable I've had since the first xbox! Its quite chunky

Originally in device manager the display showed as generic PnP, I managed to install the driver off the cd after some faffing, it now displays lg 34um95.
In the native options the monitor does tell windows/nvidia 50hz or 60hz with 16bit colour.

I'm sure I didn't set the custom profile up though, it just selected that after switching from that dam dp cable to hdmi.

I'm really hoping it's right because I'm left tainted by display port, it was hanging my computer on bootup, messed up resolution after screen saver etc, real headache. I must of hard reset my pc 40 times over the weekend. I even pulled pin 20 out of the dp cable after reading it could be supplying 3.3v back into my gpu.
A friend of mine has bought his daughter a rabbit, it keeps chewing through his Ethernet cable. Ive donated my dp cable to the rabbit
