Hi community ,

I bought R9 270x toxic a few days ago and the screed is flickering in games,this happens only in games when I'm on windows desktop there are no flickers, I'm using DVI-I VGA adapter on HDMI this thing doesn't happens ,the rare thing is this happens only when I playing games .

Need some help here.

It happens quite frequently. Just reinstall your drivers and it should solve your problems.

Can you just use digital only (HDMI, DVI-D, Displayport)? If VGA doesn't work well, you can safely ignore it if you can use digital ... since it is always best to use digital anyways.

I reinstalled windows too I tried with windows 7 and windows 8 too that doesn't work .

I can't use HDMI because my TV resolution sucks is 720p not 1080p .

So this is a TV?
In that case you definitely want to use HDMI. VGA on a TV is just going to look aweful.
The resolution on the TV doesn't matter, since all you do it set your computer to the exact same resolution as the TV (but to do that, you need to find out the real resolution of the TV, which may not be true 720p either).

Not only that, but configuring at TV to look halfway decent for computer use is VERY complicated. TVs add tons of additional image processing that mess up the way a computer looks. (In contrast,
computer monitors do not add any processing; they display pixel for pixel exactly what the computer tells it to; there are some minor exceptions to this.)

Here's two threads where I've dealt with this topic before:
http://www.tomshardware.com/answers/id-1996671/hitachi-...
http://www.tomshardware.com/answers/id-1988910/hdtv-qua...

Long story, short:
The key is to disable all the processing features that TVs adds to the picture. By default, the TV adds lots of processing that is bad for computer use. However, after you disable all this, the quality is almost as good as a monitor.

How to setup your LCD TV:
* Use DVI or HDMI (not analog).
* Always run at the native LCD resolution. You must match the resolution EXACTLY (many older "720p" TVs are not really 720p, but slightly different)
* You need to disable ALL image processing features that you can find, such as: image scaling, image sharpening, dynamic contrast, fake 120hz or 240hz frame addition, mpeg/video processing, and maybe others.



* If you would like help configuring the TV for computer use, then I need to know the exact model TV you have (both the brand name and the model number). Each brand and/or model has a range of features that need to be disabled -- often under different names.

The TV is TCL 26A12H 32" and my monitor is LG E2211 both are old .

LG E2211
* Connect using a DVI-D cable (HDMI to DVI or Displayport to DVI is also acceptible; no VGA though)
* Always run at the native resolution of: 1366x768 (unless you temporarily need to lower it to get better performance in a game)
Produce page: http://www.lg.com/ca_en/support-product/lg-E2211T-BN#
Manual: file:///C:/Users/Kevin/Downloads/ENG_E11T_S.PDF

If the native resolution bothers you, then you can change the scaling of windows (the DPI I think?): http://nvidia.custhelp.com/app/answers/detail/a_id/3153
However, always try to stick with the native resolution; computer won't output a good (or correct) picture if you don't stick with the native resolution.

TCL 26A12H

... need to see if I can find a manual that lists all the configuration options in the TVs menu...
What I do know so far:
* Use HDMI
* Run at 1366x768 (that is the TV's real resolution)
* Need a manual to know which processing features it has....

Which country is this in? EU? US? Philippines? Australia?

Can't find a manual for that model, so here's based on a newer model:
https://tcl-django.s3.amazonaws.com/medialibrary/2013/0...

[Picture] section
* Picture Mode -- "Natural" -- I don't know what this means, but maybe choose "Natural" as that seems like it might have the least processing added
* Brightness -- your choice; won't affect pixel quality
* Contrast -- your choice; won't affect pixel quality (up to a point)
* Saturation -- try to adjust it so colors look rather normal like your monitor
* Sharpness -- 0 -- turn all the way off. I am guessing that 0 means off, but it is possible that 10 may mean off and anything below that means blur the image. (TVs are weird) You want no sharpening added; try 0 to see if that removes it correctly.
* Tint -- try to adjust it so colors look rather normal like your monitor; I don't know what number means normal colors.
* Color Mode -- your choice; this will pick the base color for "white" ... where white will appear redder (warm), neutral, or bluish. Try "Normal" and "Cool"
* Backlight - your choice; won't affect pixel quality
* Dynamic Backlight -- off -- turn off because this will constantly change the screen brightness based on how much of the screen is dark or bright, which is not good for computer use (it means your greyscale levels are always changing and sometimes the change can be annoying if you see it happen). Although, depending on how you use the TV, you might want this on. This will not affect pixel quality as much... so if you like it on for movies or games, then it's probably ok.
* Dyanamic Light Sensor -- off or your choice -- this changes the brightness based on the room; so it changes less than dynamic brightness, but it means your tv is changing greyscale levels yet again.
* Geometry -- (this option might not affect you; I don't know what it's options are, but disable any processing features that would change the pixels; you can list all the options in a reply if you aren't sure.)
* Advanced > Zoom Mode -- don't know what the options are, but you want a 1:1 or no zoom or something like that; This is actually a pretty important setting to get right. If you want to list the options, maybe I can recommend which one, but basically you want the one that does not stretch or distort the signal from the computer to fit the screen in any way; you want it to show pixel for pixel perfect.
* Advanced > 3DNR (Noise Reduction) -- Off -- this could ruin pixel perfect images, mess up antialiasing on text, and cause other issues, if on
* Advanced > Film Mode -- Off -- yet more image processing; might be ok if it is guaranteed to ONLY work if you are playing a video, but it might kick in during other use that you don't want it to, thus, might be better to keep off

If you see any other settings on your model, let me know.

Also, let me add again that you should:
* Use ONLY HDMI
* Run ONLY at 1366x768 resolution.
for this TV to look fairly decent.

Your welcome. .... and, I hope you can see the difference. Be sure to check out things like text, or anything with sharp edges or that requires pixel precision. Those should be more accurate with these settings.
To be fair, the way TVs are setup is not bad. It's just they only work well for things like video or pictures where you don't care about the details being very accurate. But when you use a computer, you usually want all those little details to be very precise and accurate.

I have this problem too, I am using Sapphire 2GB R9 290X Dual-X though with my ACER P205H LCD monitor

Driver : AMD Catalyst 13.12, using DVI-VGA link ( I do not know if this is the problem because the flickering only happens in some games. )

Try a DVI-D cable; if you don't have one, order one:
http://www.monoprice.com/Category?c_id=102&cp_id=10209&...

If that doesn't help, try to take some pictures with a camera and upload them to imgur.com.
Then start a new thread and post the pictures and try to describe the problem. You can put a reply in this thread linking to your new thread, if you want.
