Hey guys, I think im retarded for asking this but can I use this monitor BenQ XL2411Z-3D at 144hz with this old gfx ATI RADEON 4890? I mean can I use this monitor at all? or its not affected.

Thanks for help.

Update:
THIS monitor supports Freesync and is similar to the Benq in price and quality.

(I believe older models had an overdrive issue which was fixable with a firmware update, and that newer models have this fixed by default.)

Both are:
- TN
- 1ms response
- 144Hz
- 24"
- similar price ($250 AOC vs $275 Benq, at least checked at pcpartpicker)

The Benq is 3D, but you can't use that feature without an NVidia card and NVidia 3D goggles.

*On the other hand, Freesync gives you a much, much better experience in gaming than normal, synchronous monitors.

Here's some more info about the latest Freesync driver update to fix the Freesync low-end issue...
well that card is rather old so getting 144 FPS is going to be next to impossible, but if there is a game that does run at 144 FPS then you will get the full 144Hz experience. so yes it will work, but you are not going to see the full benefits with that current card.
 




This is my pc spec:

processor: Intel QUAD CORE Q9400 2.66 ghz
gfx: ati radeon 4890
motherboard: Intel® Desktop Board DG45ID
ram : 8gb

Considering this motherboard Intel® Desktop Board DG45ID and rest of my pc specs, will I be able to upgrade my GFX to this: http://www.gigabyte.com/products/product-page.aspx?pid=5462#ov

will it work? and will my benq work normally then?
 


thanks for the help, lets cross the fingers my motherboard will support the new gfx 😀
 
Hey,
I would find official verification that your HD4890 will work at 1920x1080, at 144Hz.

It WILL may work via the DVI-DL connector, however I don't know if it will work at 144Hz. Possibly only 85Hz but I can't find any solid info from the AMD site, or elsewhere. Not even someone who actually tried that combo.

The monitor site only states a 100Hz min (100/120/144). Perhaps it does work at lower refresh rate but I'd have to check the manual.

You've also chosen a 3D monitor with NVidia 3D support. You may not want to play 3D at all, or maybe you are upgrading to an NVidia setup later but thought you should know.
 


If it has Nvidia 3D support does that mean I need to get NVidia gfx card?
 
More info.

1) You need a POWER SUPPLY that can handle that R9-380. The one you linked needs a 500W with an 8-pin (or 2x6-pin with an adapter to 8-pin).

If you don't have that, you may wish to consider a similar NVidia card if you don't want to buy a new power supply.

2) Your CPU is going to be a pretty big bottleneck, so look at game CPU specs. How much will vary quite a bit. Some games like Tomb Raider are far less CPU intensive.

It scores about 1134 per core so is weaker than a FX-4300 (1411) for reference. Not horrible, and many games with the newer GPU will run fun but keep that in mind.

3) When gaming on a 144Hz monitor you need to be aware of how VSYNC works. You should either:
a) Use Adaptive/Dynamic VSYNC
b) Use the "half" method of the above (to cap at 72FPS), or
c) don't use VSYNC (screen tearing)

Running VSYNC ON but outputting below 144FPS will cause STUTTERING in your game.

I use Adaptive VSync (for AMD can use RadeonPro to force on Dynamic) and tweak game settings for my 60Hz monitor so I rarely drop below 60FPS. It's a balancing act if you want to optimize. If you NEVER drop below you have to drop settings low enough so visually your experience is lower. If you are dropping below too often (VSync is turned off automatically) then you get a lot of screen tearing.

4) Again, you chose a monitor with NVidia 3D support. It will only work in 2D mode with an AMD card, though you'd need the 3D goggles. Unless you got a deal, there may be a better monitor if you don't want 3D.

5) Do you have 64-bit Windows?
I assume you do since I see 8GB of system memory listed but you didn't clarify that. I'd suggest Windows 10 if you don't have it, but if not plan carefully to avoid losing data (if you clean install).

6) FREESYNC:
You might want to investigate Freesync/GSync, though it probably won't make sense at this budget.
 


You would need both a supported NVidia card and the NVidia goggles AFAIK to use 3D in games. However, that's more demanding on your system so I wouldn't recommend it. Adding in the cost of the goggles for example, I'd put that towards a Freesync monitor instead for smoother 2D gaming than a normal synchronous monitor can provide.

If you buy the monitor right now you simply work in 2D mode (I again can't verify 144Hz at 1080p for an HD4890 works though).
 


You don't sound as certain as you did the first time when you said it would work nicely with his HD4890.

Also, as I said before the monitor page states only 100/120/144Hz refresh rates. It may and probably does work lower, but I can't recommend anything without verifying for sure.

Just because a card has DVI-DL doesn't mean it will operate at what DVI-DL is rated for. You absolutely must verify what an HD4890 specifically can handle.

*Single link DVI can handle up to 1920x1080 at 60Hz. So the need for DVI-DL only happens if you need to support a higher resolution, or higher refresh rate. Thus, the card may only support 1080p at 85Hz. I just don't know.
 


Oh I see, maybe I could get that after I upg my pc first hahaha, btw what bottleneck could I experience IF i was to upg my gfx to http://www.gigabyte.com/products/product-page.aspx?pid=5462#ov
 
CPU bottleneck:
The CPU feeds the GPU data, so if it's too slow then the GPU is left waiting.

*The amount of CPU bottleneck varies by the game, and the settings chosen for that game.

So I can't specify exactly but I will attempt to provide examples. Please note it doesn't mean you should get a lower performing GPU. That's a pretty nice upgrade for your system. It means you'll get lower performance than someone with a faster CPU and the same GPU.

So let me just state that then throw in some data but offhand I'd estimate between almost no bottleneck (fairly rare) to 70% bottleneck (worst-case) with perhaps a 40% as the average. That's a very rough guess.
 



Thanks for great explanation. I surely will experience some bottleneck, but I mostly need my pc for fps game COUNTER STRIKE GLOBAL OFFENSIVE, and I really need that 144hz , do you think i could achieve that 144hz with that new gfx upgrade gigabyte ati radeon R 380 4gb that I linked and benQ monitor i linked?
 
THIS is just an example of how CPU scaling affects frame rate:
http://www.gamersnexus.net/game-bench/2182-fallout-4-cpu-benchmark-huge-performance-difference

Here's a game (Tomb Raider) that doesn't need a lot of CPU power:
http://www.techspot.com/review/645-tomb-raider-performance/page5.html

*You can roughly estimate what performance you'd get in a game by looking at "CPU scaling" graphs for whatever game you're interested in. As I said about you get roughly 80% of what an FX-4300 does.

Of course the graph also depends on the GPU as well, but this is just to get you in the ballpark.

So.. summary:

An R9-380 4GB is a nice upgrade to your system. Some future DX12 games will likely make very efficient use of your CPU, possibly eliminating the CPU bottleneck (only for those DX12 titles running under Windows 10).

Meanwhile, just tweak your settings to maintain an optimal frame rate and investigate when and where to use VSYNC, Adaptive/Dynamic or VSync off because that's pretty critical.

In general I don't recommend 3D for people on a budget. For active shutter goggles for example you need to DOUBLE the frame rate which is generally not practical, and of course the money spent for the goggles (and probably higher monitor price) can go elsewhere.

I hope this helps. I have to go soon but I can answer a quick question or two.
 
R9-380 144Hz?

Yes. Absolutely.

That doesn't mean you'll achieve 144FPS in a particular game, but it does mean the GPU supports 144Hz at 1080p. The monitor will update at 144X per second regardless of what the computer side is doing, though the GPU must be capable of supporting 144Hz, 1080p to start with.
 
A lot of CSGO people don't use VSYNC since it's snappier without.

You will get screen tear without (varies from minimal to horrible). I would suggest considering using RadeonPro and experiment with Dynamic VSync to cap to 144FPS (and turn VSYNC OFF below) if screen tear is annoying.

144FPS is probably very achievable with your setup even with that relatively weak CPU but I can't be certain.

Anyway, you might want to review some of my points later on but i have to go.
 


So I can get 144hz refresh no matter of my gfx and pc side? I will still have 144hz refresh rate?
 


thanks for the help, talk to you later :)
 


Um...
1) What I'm saying is that the R9-380 can output 144Hz at 1080p so you're fine there.

2) The actual FPS depends on the game and settings chosen. For example, you might get about 50FPS in a particular game though the monitor will always update 144X per second independent of the computer.

(In which case I'd recommend VSYNC OFF, or try to adjust with Half Dynamic VSync but I don't want to confuse the issue further).

3) Finally, as I said before I do NOT KNOW if the HD4890 is capable of outputting 144Hz at 1080p. I simply could find no info to confirm, and now suspect it is NOT POSSIBLE.

My best guess is 85Hz, and if you read what I said the Benq you ask about says on its site it supports 100Hz/120Hz/144Hz and does not confirm if it supports lower, though feel free to download and read the manual.

*Long story short, I do not know if the HD4890 will work at all with that monitor. I suspect it will, and that the monitor supports below 100Hz however I have no more time to look into this.

I hope that helps. Maybe buy the graphics card first.

That's pretty CONFUSING to most people, so perhaps just watch THIS video from NVidia to understand how asynchronous mode works (update: not the video I thought, but anyway more info can be found online):
