Problem with the resolution of a TV

post #1 of 14
Thread Starter 
Hello, everyone!

My monitor (Philips 230C) went for RMA and now I'm using my TV (32" 1080р Toshiba REGZA 32LV733G) as a monitor, otherwise I have to stay without a computer for a couple of weeks. I don't have a spare HDMI cable and I'm using a VGA one temporary. I have a problem with the resolution on the TV. The maximum resolution on that TV is 1920x1080, but I'm only able to set 1360x768 in Display settings in Windows. I was trying to fix the problem through the AMD drivers(Catalyst 11.5), but it didn't help. Here are the settings, which I made, but unfortunately without a result -


I've made an experiment and a strange thing happened. When I moved the VGA Cable and the VGA to DVI converter to the other DVI port on my card (Asus EAH4850) the maximum resolution became 1600x900, but still the native resolution couldn't be set.

Here is a screenshot from Display Settings in Windows -


Is the problem in the drivers or the VGA cable itself is causing this? I'll be very grateful, if anyone helps, because it's awful to work on that big screen with so small resolution.

PS. Excuse me for any grammar or spelling mistakes in my post.

I could very well be your TV's VGA port that maxes out at 1360x768, I beleive this is common. You would have to look at your TV's user manual and check the VGA port specifications.

Most TV don't expect a high resolution device to be connected via VGA, I beleive they invest more $$ in the HDMI controler on the TV itself.

try switching cables, also try using an HDMI cable.

But I'm curious to know... HDTV's don't use a 75hz refresh rate. Either 60, or 120 (or all the way up to 600 something if you count subdriving which I don't)

So if yours is 60hz, drop the refresh to 60hz.

Actually the refresh rate is 60Hz, I dunno why the Catalyst is showing 75. I think I have another VGA cable, I'll try switching them.

As thestef said, they make VGA obsolete by choice.
VGA cables have enough bandwidth to get 1920*1440 and even 2560*1600.

I have a 42" Toshiba Regza connected to my HTPC, and if I remember right, it doesn't support 1080 resolution with VGA.... get a DVI to HDMI cable and you'll be set.

So the problem is in the cable, right? I can use another one, but I can't find it at the moment, I think I'll have to wait till tomorrow.

EDIT: @eazy, thanks for your input. I think I'll have to buy a HDMI cable.

Gee, thanks for that

What I meant was since you don't have a SPARE HDMI cable, use an EXISTING HDMI cable from one of his OTHER components to see if that gives him better results. And if he doesn't have one at all.... GO BUY ONE!

OK, man, just calm down.
I can't go buy one at the moment, because it's 11 p.m. in my country. Tomorrow it will be done and I will update the thread with the results. Thanks everyone!
