Question: Card seemed fine but monitor could not handle. New monitor the screen goes grey/white. Why is that? Power cord/supply fine. Drivers fine.
Document: I would avoid this product like the plague. I purchased it 6 months ago but about 1 month ago I started getting 'black screens' while playing 3d games. The computer itself would keep functioning but would get no signal from the video card until a reboot. Thinking it might be a power issue I replaced the power supply with a new 750W supply. The issue kept recurring. Over the last month the issue kept happening more and more frequently so I contacted XFX.
I'm not a gamer but needed more ports and graphics power. This unit fits the bill. It runs four monitors and a Sanyo 47&#34; LCD Television. My computer was lacking in power so I had to do a power supply upgrade but I was aware of that going into this project. The card does everything I've asked of . I'm completely satisfied.
Ridiculous, as I had been using the monitor for several years without issue and all power saving features on my motherboard were disabled. I informed them of this and have not received any reply.I understand sometimes graphics cards can sometimes go bad but that's why cards have a warranty. While it was functioning this card was wonderful, but I would strongly suggest buying it from any other vendor besides XFX.
But this card handled it so smoothly that I decided to get a third monitor. This thing can handle BF3 beautifully across 3 monitors. Note: You must run 2 of the monitors via mini display port for Eyefinity to work across more than 2 monitors. If your monitors do not support mini display port you will need 2 mini display port to "active" DVI adapters.
Sometimes my monitor will turn off and on and Windows will make the sound it makes when you plug in a new device and then notify me that there's a problem with the video card driver. It seems like my card is failing and the support representative just told me to try a new bridge and try swapping out the video cards. I tried a new bridge and the problems persisted.In addition to these problems, the XFXForce support site is just very bad. It's poorly designed and hard to navigate.
I purchased this to game on my new 27&#34; 2560x1440 monitor, and I've yet to find a game that makes it stutter. Battlefield 3, Crysis 2, League of Legends, everything runs buttery smooth at max.My only gripe is that AMD cards don't have CUDA support, which means that I haven't been able to use it when editing videos in Premiere / After Effects.So, if you're just gaming, buy this baby and you'll be good for years to come.
It's so fast that I have to turn on VSync to bring the framerate down to match the 60Hz refresh rate on my TV so I don't get so much screen tearing. Probably going to end up getting a monitor/TV with a 120/240Hz refresh rate down the road so I can enjoy the high frame rates.The core edition comes with a huge heat sink and one fan, and it runs at respectable temps in my Cooler Master Storm Scout case.
A fine piece of hardware.
I was looking to upgrade my slightly dated Nvidia graphics card for playing Battlefield 3, SimCity, and several other games. This card is a beast! It'll handle almost anything I throw at it. I am using a 1920x1080 display right now but I am planning on switching to a 2560x1440 soon and it should handle it no problem. My only complaint is the fan. It can get loud, but only when you're gaming. Get this card if you need performance on a budget.
This is for a new system build. It's very fast and quite. I chose the 7870 over the 7900 series because this card can be easily OC'd to reach the same performance of the 7950 and close to the 7970. Installing this card was straight forward, no problems or driver issues to talk about. It runs cool and silent. It never really ramps up the fan to the point I can here it over the case fans plays all new and newer games and max setting with stunning fluidity.
Answer: 1) You can try another DVI cable to your monitor from the PC. Or if your new monitor has HDMI slot, you can try using a HDMI cable instead.2) You can try the card on another PC to see if the card works. (If it doesnt, possibly card faulty, even though fan is running or you need to check the motherboard settings to enable the PCIE settings for graphics.) 3) Also try the new monitor with the old graphic card to see if the monitor itself has any issues. You may never know you might get a "dud" on your new monitor.
