I have a problem connecting my PC with my LED TV, it's a Vivax 24le20, connecting with VGA gives a nice clear picture, while with HDMI it's all blurry. I have an R9 270x 2gb gddr5.
I think it's because the TV doesn't a "PC mode" and I wonder if it could be fixed.

That is your answer. I have a Samsung 32" tv as my PC monitor and at first I thought that the tv was crap. Luckily it has a "PC mode" and it's quite sharp with it turned on.

I don't think it can be "fixed" if the mode is not implemented on the tv.

To be honest, I would much rather use a dedicated PC monitor over a tv. PC monitor have sharper picture. Why I went with a tv? It was the cheapest way I could get 32".

A 32" monitor would run me $400 while the "tv" was only $180 (at the time of purchase).

Ah, I guess that's what I expected. Though I'd like to know, would an hdmi to vga adapter work to fix my issue? I think it would since the "PC" option from sources defaults to VGA

I'm curious as to why you want to use the hdmi input instead of vga. You really won't gain anything. In fact going vga to hdmi, I don't think you will get sound. Besides, most tv's today have garbage speakers.

If the picture is super sharp with vga, I'd stick with it.

If your reasoning is different, I'd like to know what it is.

Hi,
The reason HDMI isn't sharp is because you don't have it setup properly in the video control panel.

There is an HDTV section, so you'd be choosing 1080p_NTSC@60Hz or whatever the connection is called. You do NOT try to set it up by choosing a resolution from the desktop like "1920x1080".

"PC MODE" simply means there is a scaler to take in a video input and make the HDTV work like a TV monitor. HDMI isn't connected to this path.

As said, if the picture in VGA works well, there's not much reason to use HDMI.

In fact, on my older HDTV I can get 60Hz via the VGA input, but only 30Hz via HDMI input. So I can game at 1366x768 at 60FPS via VGA, but same res at only 30FPS via HDMI.

Summary:
- HDMI is the optimal solution if setup correctly (also don't need an additional audio cable)
- VGA can look about the same (arguably)
- some older HDTV's may not support full Hz (FPS) on certain inputs

Excellent point. There are a few games that will only play at 24fps if connected to a tv.
To get around it I have to create a custom resolution. Instead of 1920*1080, I would set it to like 1919*1079 in order for it to show up.

Oh, I'm doing a dual monitor set up, my old 4:3 sync master 1280x1024 monitor (I love it because it's overclocked on 75hz), and this TV. I want to use it because of the 1080p with certain games that don't support 4:3 aspect ratio and because hd hello.
Seems as though my TV doesn't support the scaling well, guess I'll just use it for my PS2 and get a real DVI PC monitor, would save me the headache.

I picked up a 22" 1080p LG monitor with vga/dvi for $79. Back light bleeds out a bit but he doesn't seem to care. The viewing angle is terrible, very narrow. As long as you sit in front of it you're fine.
