ATI HD5770 1GB with Sony KDL-32EX01 = colour problem

I bought new LCD which is Sony KDL-32EX301 which supports full HD i.e. 1080p. I got XFX ATI Radeon HD 5770 1GB graphic card which use to work absolutely fine with old monitor ( which was 22" LCD).

Since I've installed Sony TV with computer with HDMI cable, desktop keep changing colour. I'm using driver from XFX, version is: 8.741.0.0

Does upgrading driver will resolve the problem?

Specs of computer are:

• ASUS P5E3
• Intel Q6600 @ 2.4 GHz
• XFX ATi HD 5770 1GB
• 4 GB (4x1) DDR3 - Dual Channel Linear Mode
• Windows 7 Ultimate - 64 bit

Your problem is more than likely not the 5770, if you can't test it on another monitor the read some of the Sony info on updates. Sony eSupport - KDL-32EX301 - Software Updates & Drivers

I found if a TV has the ability to connect to a PC as a monitor the HDMI is best for audio and the VGA port for video, your 5770 should have supplied a DVI-HDMI adapter and a DVI-VGA adapter, good luck.

yeah but I don't want to compromise video quality. One of the reasons to get 1080p LCD was to run computer games on 1080p which I don't think is possible with DVI connector?

Ummm, I run a Vizio 37" 1080p at full HDTV 1920x1200 with a 5870, the 4870 I upgraded from did it as well and I use a DVI-VGA adapter to do it with. The GPU manufacturers have these adapters to ensure the GPU can put the signal out to the TV/Monitor as it is expected. Your TV manufacturer has the ideal setup listed in the manual so that you'll get what you expect from it. I run Blu-Ray movies and HD Video all the time.

so your advice is to use DVI-VGA cable for video, will it resolve the problem?

Based on what the Sony Manual says it should, most TV's are using the HDMI for the audio side if the GPU has audio, which the 5770 does, and either DVI or DVI-VGA for the PC, the TV manufacturer sets the standard on how a PC is connected not the video card manufacturer. IF the VGA is the component set you won't lose any capability, just be sure to check your manual to see if there are settings you need to setup in the TV's menu, I quickly breezed through the PC section of your Sony's manual in .pdf on the net.

I just updated video card driver to 8.753.0. Also updated firmware of LCD tv, hopefully it should resolve the issue of colour flickering, if not I'll try to connect with DVI cable (if I can find it)

Keep us up to date, I think once it's doing what you want of it you'll be most satisfied.

Just to let you know, I am running it on 1920x1080 pixels and it keep changing colours. Just changed it to 1360x768 and it hasn't changed colour yet, I guess problem is running on high resolution with HDMI cable. I'll try the same with DVI cable tomorrow

Also be sure of what Hertz Freq it will need, some TV's will run at 59MHz only others at 60MHz only and others have no care either way. Some HDMI cables can't cope either, I'm sure you spec'd out the requirement which is probably HDMI v 1.3 some cables are 1.1 or 1.2 and often can be problematic.
